Mesmo considerando os avanços nos estudos de micropropagação em Hevea spp., a compreensão dos estímulos e condições necessárias para o estabelecimento do cultivo in vitro ainda são limitadas. Uma das razões para isto acontecer é devido à falta de um protocolo eficiente para a propagação de clones elites de seringueira em larga escala. Neste sentido, investigamos o efeito do ácido 2,4-diclorofenoxiacético na indução de calos em segmentos foliares de Hevea spp., bem como o uso do PPM® (Plant Preservative Mixture) na inibição de contaminações. Folhas juvenis de seringueira foram inoculadas em meio de cultura MS (Murashig Skoog) suplementado com 2,4-D (0; 0,25; 0,5; 1,0; 2,0 e 4,0 mg L-1) com biocida PPM® (0 e 1,0 mL L-1). Após 60 dias foi possível observar maior porcentagem de sobrevivência e expressiva oxidação fenólica na presença do PPM®. As concentrações de 2,4-D (2,0 e 4,0 mg L-1) combinadas com PPM® (1 mL L-1) foram eficientes na inibição de contaminações microbianas. A indução de calo ocorreu no tratamento contendo 1 mg L-1 de 2,4-D e 1 mL L-1 de PPM® e formou um calo compacto com coloração branca. O protocolo utilizado neste trabalho foi eficiente para desinfestação dos explantes foliares de Hevea spp.

Soil fertility management and N-fixing species can support the ecosystem-level restoration of disrupted biogeochemical cycles in tropical degraded environments. However, the effectiveness of N-fixers during tropical forest restoration remains unclear. We hypothesized that tree legumes adjust growth, nonstructural carbohydrate allocation and foliar nutrients under different fertilization regimes. We compared the following six tree legume species: three native nonfixers (Cenostigma, Senna and Dipteryx), two native N-fixers (Clitoria and Inga) and an introduced N-fixer (Acacia). Twenty-four months after the experiment was established, fertilized plants increased growth rates and starch allocation to leaves, whereas unfertilized plants primarily increased their biomass and starch allocation to roots. The greater tolerance to nutrient deficiency of the Acacia than other native tree legumes was due to Acacia’s ability to adjust carbohydrate pools. N-fixers adjusted the shoot-to-root ratio and soluble sugar allocation to leaves, increasing biomass growth. The three N-fixing species were especially suitable for restoration because Acacia had tolerance of nutrient deficiencies, Clitoria and Inga had fast growth and biomass production. Hence, fertilization management and N-fixing species may have a considerable impact on C stocks in different plant compartments. Overall non-structural carbohydrate adjustments influence growth responses of species, especially the ratio between leaf and root tissues. Our findings suggest that this aspect should be considered as a tree species selection criterion for forest restoration programs in the Amazon region.

Objectives Tree legume species play an important role in forest restoration in the tropics. Understanding how different species adjust carbohydrate allocation and growth under distinct nutrient availability will enhance the success of restoring degraded areas. Data description A 2-year tropical forest plantation of the Forest Restoration Program of the Balbina Hydropower Dam was evaluated. Three non-N-fixing (Cenostigma tocantinum, Dipteryx odorata and Senna reticulata) and three N-fixing (Clitoria fairchildiana, Inga edulis and Acacia spp.) tree legume species were either fertilized or not fertilized. Growth rates and biomass allocation were calculated, and carbon (C) fractions and nitrogen (N), phosphorus (P) and nonstructural carbohydrate (NSC) concentrations were determined. Multiple nutrient additions increased the growth rates and aboveground biomass production of fertilized plants. According to the results presented, different species and N- fixers respond differently to fertilization regimes. The authors encourage the use of the presented data in meta-analysis studies that consider the fertilization or nutrient deficiency effects on growth, carbohydrate and nutrient responses. N-fixing species with high biomass growth and foliar N are important for restoring N and C cycles in nutrient-limited soils. Fertilization treatments are fundamental during the early stages of forest plantation development.

Aniba parviflora (Meisn.) Mez (Lauraceae) is an aromatic plant of the Amazon rainforest, which has a tremendous commercial value in the perfumery industry; it is popularly used as flavoring sachets and aromatic baths. In Brazilian folk medicine, A. parviflora is used to treat victims of snakebites. Herein, we analyzed the chemical composition of A. parviflora bark essential oil (EO) and its effect on the growth of human hepatocellular carcinoma HepG2 cells in vitro and in vivo. EO was obtained by hydrodistillation and characterized by GC‐MS and GC‐FID. The main constituents of EO were linalool (16.3±3.15), α‐humulene (14.5±2.41 %), δ‐cadinene (10.2±1.09 %), α‐copaene (9.51±1.12 %) and germacrene B (7.58±2.15 %). Initially, EO's cytotoxic effect was evaluated against five cancer cell lines (HepG2, MCF‐7, HCT116, HL‐60 and B16‐F10) and one non‐cancerous one (MRC‐5), using the Alamar blue method after 72 h of treatment. The calculated IC50 values were 9.05, 22.04, >50, 15.36, 17.57, and 30.46 μg/mL, respectively. The best selectivity was for HepG2 cells with a selective index of 3.4. DNA Fragmentation and cell cycle distribution were quantified in HepG2 cells by flow cytometry after a treatment period of 24 and 48 h. The effect of EO on tumor development in vivo was evaluated in a xenograft model using C.B‐17 SCID mice engrafted with HepG2 cells. In vivo tumor growth inhibition of HepG2 xenograft at the doses of 40 and 80 mg/kg were 12.1 and 62.4 %, respectively.

The balance between efficiency of absorption and use of light energy is fundamental for plant metabolism and to avoid photoinhibition. Here, we investigated the effects of light environments on the photosynthetic apparatus of tropical tree species of three successional groups (pioneer, mid-, and late successional) subjected to different light conditions: full sunlight (FS), moderate shade (MS), and deep shade (DS). Twenty-nine ecophysiological parameters were correlated with each other. The pioneer species exhibited better photochemical performance and a more efficient antioxidant enzymatic system in comparison with the other successional groups. Plants in FS showed higher intensity of lipid peroxidation, with superoxide dismutase having a prominent role in the antioxidant system. At lower irradiance the enzymatic activity was reduced, and the photochemical efficiency was the preferred way to reduce oxidative damages. P was highly related to photochemical yield, and the N modulation amplified the light harvesting complex in DS to the detriment of the antioxidant system. Despite evidence of cell damage, most species exhibited the ability to adjust to high irradiance. Contrary to expectations, Hymenea courbaril (late-successional) exhibited higher plasticity to fluorescence, nutritional, and antioxidant parameters. Only Carapa guianensis (late-successional) displayed photoinhibitory damage in FS, and Ochroma pyramidale (pioneer) did not survive in DS, suggesting that acclimation to shade is more challenging than to high irradiance.

The Amazonian Aniba species are world-renowned for their essential oils (EOs). The molecules derived from EOs have been intensively investigated in regards to their potential for disease control in plants. The aim of this study was to investigate the antifungal properties of Aniba canelilla EO (ACEO) and Aniba parviflora EO (APEO) when used against eight phytopathogenic fungi. Gas chromatography-mass spectrometry (GC–MS) analysis of oils showed that 1-nitro-2-phenylethane (∼80%) and linalool (∼40%) are the major compounds in ACEO and APEO, respectively. The ACEO and APEO treatments displayed remarkable antifungal effects against Aspergillus flavus, Aspergillus niger, Fusarium oxysporum, Fusarium solani, Alternaria alternata, Colletotrichum gloeosporioides, Colletotrichum musae and Colletotrichum guaranicola, for which the IC50 values ranged from 0.05 to 0.28 μL mL−1 and 0.17 to 0.63 μL mL−1, respectively. Furthermore, the oil caused the inhibition of conidial germination by at least 83% for ACEO and 78% for APEO. The ACEO and APEO at 5 μL mL−1 induced leakage of nucleic acids and protein, suggesting that inhibition could be linked to the breakdown of membrane integrity of the conidia. In addition, the detection of fluorescent dye propidium iodide (PI) on F. solani conidia treated with ACEO and APEO indicates damage on the conidia cytoplasmic membrane. The findings of this study may be of biotechnological interest for the development of new plant protection products, with the advantage of being less harmful than the agrochemicals currently available.

A deficiência hídrica é considerada um fator que produz danos significativos durante o período de estabelecimento e de crescimento dos plantios. O objetivo deste estudo foi investigar características morfofisiológicas e bioquímicas de folhas de mudas de seringueira em resposta à deficiência hídrica e, posterior, reidratação. Plantas jovens de Hevea brasiliensis do clone RRIM 600 - Rubber Research Institute of Malaysia foram divididas em dois tratamentos, tratamento 1 = plantas irrigadas (IR) e tratamento 2 = plantas não irrigadas (NI). Nestas plantas, a fotossíntese (A) foi acompanhada durante todo o período experimental (0, 10, 25, 32, 48, 52 e 68 dias). O potencial hídrico foliar (ψw) foi determinado usando-se uma câmara de pressão do tipo Scholander, a fotossíntese (A), condutância estomática (gs) e transpiração (E) foram determinadas usando-se um analisador de gás infravermelho (LI-6400XT, LI-COR, Lincoln, Nebraska, USA) e o conteúdo de carboidratos foliares e de prolina foram determinados por espectrofotometria (Amersham Biosciences Ultrospec 3100 pro). O ψw, A, gs, E e o conteúdo de amido foliar no tratamento NI foram reduzidos durante os primeiros 32 dias, em que A atingiu valores próximos a 0 μmol m-2s-1.Porém, houve aumento da concentração de açúcar solúvel total e de prolina (tratamento NI) neste mesmo período. A recuperação da fotossíntese (NI) ocorreu após 22 dias depois da reidratação, quando comparado ao tratamento (IR). Portanto, pode-se concluir que o clone RRIM 600 possui tolerância ao estresse hídrico em termos de como lidar com o estresse hídrico progressivo, mas a recuperação ao estresse foi relativamente lenta.

Isoprene (C5H8) is a hydrocarbon gas emitted by many tree species and has been shown to protect photosynthesis under abiotic stress. Under optimal conditions for photosynthesis, ~70%–90% of carbon used for isoprene biosynthesis is produced from recently assimilated atmospheric CO2. While the contribution of alternative carbon sources that increase with leaf temperature and other stresses have been demonstrated, uncertainties remain regarding the biochemical source(s) of isoprene carbon. In this study, we investigated leaf isoprene emissions (Is) from neotropical species Inga edulis Mart. as a function of light and temperature under ambient (450 µmol m−2 s−1) and CO2-free (0 µmol m−2 s−1) atmosphere. Is under CO2-free atmosphere showed light-dependent emission patterns similar to those observed under ambient CO2, but with lower light saturation point. Leaves treated with the photosynthesis inhibitor DCMU (3-(3,4-dichlorophenyl)-1,1-dimethylurea) failed to produce detectable Is in normal light under a CO2-free atmosphere. While strong temperature-dependent Is were observed under CO2-free atmosphere in the light, dark conditions failed to produce detectable Is even at the highest temperatures studied (40 °C). Treatment of leaves with 13C-labeled sodium bicarbonate under CO2-free atmosphere resulted in Is with over 50% containing at least one 13C atom. Is under CO2-free atmosphere and standard conditions of light and leaf temperature represented 19% ± 7% of emissions under ambient CO2. The results show that the reassimilation of leaf internal CO2 contributes to Is in the neotropical species I. edulis. Through the consumption of excess photosynthetic energy, our results support a role of isoprene biosynthesis, together with photorespiration, as a key tolerance mechanism against high temperature and high light in the tropics.

We conducted this study to understand the dynamics of revegetation by examining the levels of mineral nitrogen (NO3− and NH4+) in soil and the capacity of nitrogen use by the principal species growing in secondary forest in central Amazonia. For this, we measured the nitrate and ammonium content of soil, leaves and xylem sap, nitrate reductase activity of the leaves and free amino acid contents of the xylem sap in five tree species (Vismia cayennensis, Vismia japurensis, Bellucia dichotoma, Laetia procera and Goupia glabra) over a chronosequence during recovery after pasture abandonment at two seasons. Soil ammonium was higher in the dry season and nitrate higher in the wet season and increased these with pasture abandonment age. V. japurensis, B. dichotoma and G. glabra decreased foliar ammonium due to pasture abandonment in the dry season and foliar ammonium increased in L. procera in the wet season. V. japurensis and V. cayennensis showed a decrease in nitrate reductase activity, while B. dichotoma and L. procera showed an increase. Xylem nitrate decreased in L. procera and B. dichotoma in the dry and wet seasons, respectively, and ammonium increased only in V. japurensis and V. cayennensis in the wet. Xylem arginine increased in all plant species after a period of pasture abandonment (except B. dichotoma). Tree species growing in pasture abandoned areas didn’t show the same pattern of use of nitrogen, and this can be important in order to understand the nitrogen metabolism of trees in the Amazon region during forest restoration.

The Brazil nut tree (Bertholletia excelsa Bonpl.) is widely distributed in the Amazon region. It is subject to different rainfall regimes, particularly in El Niño years. Here, we demonstrate how biomass growth, gas exchange and biochemical traits of young B. excelsa plants were affected by imposed drought stress and subsequent rehydration. Four-month-old young plants were acclimated in a greenhouse for 15 days and received daily irrigation, after this period they were separated into two treatment: well-watered (control plants, WW) and water deficit (drought-stressed plants, DS). After 58 days of water deficit, the net photosynthetic rate (Pn) of the plants in the DS treatment regime reached values close to zero, water use efficiency significantly increased, and midday leaf water potential (Ѱleaf) reached a mean value of −4.7 MPa. The recovery of Pn and Ѱleaf to control levels was re-established after 16 days of rehydration. The DS treatment regime led to lower level of biomass (37%) when compared to plants in the WW treatment regime. The DS treatment plants had higher leaf concentrations of total soluble sugars, whereas the starch content was higher in the WW treatment regime. Our results suggest that (i) B. excelsa has a high physiological plasticity with respect to drought stress and (ii) the recovery of physiological traits was followed by the recovery of the absolute growth rates of the DS plants in the short term. These ecophysiological responses demonstrate the strong potential of this species for establishment in forest plantations in the Amazon region and its resilience during drought events.

The oils of species from the genus Carapa are widely used for the control of diseases and the production of cosmetics. In this study, the lipidomic profiles of the oil from Carapa guianensis and C. vasquezii seed were characterized with an emphasis on the major compounds and their synergistic implications for the inhibition of phytopathogenic fungi (Aspergillus flavus, A. niger and Fusarium oxysporum). C. guianensis oil contained 42.3% methyl oleate, 26.0% methyl palmitate and 12.5% oleic acid as their principal compounds. C. vasquezii oil contained 38.6% methyl oleate, 20.5% methyl palmitate and 14.5% oleic acid. The presence of myristic acid compounds (0.1%), methyl 11-eicosanoate (0.1%), scalene (0.1%) and β-sitosterol (0.1%) was the special feature of the oil from C. guianensis. On the other hand, arachidic acid (0.15%) was found specifically in C. vasquezii. The C. vasquezii and C. guianensis oils showed a deleterious effect against the three phytopathogenic fungi, with IC 50 values ranging from 6.5 to 47.8 μL mL−1 and 19.7 to 71.2 μL mL−1, respectively. The oils from Carapa seeds had inhibitory effects on the conidial germination of A. flavus, A. niger and F. oxysporum. The oils from C. guianensis and C. vasquezii had similar lipidomic profiles for the major compounds, but C. vasquezii oil had a greater per-centage of saturated fatty acids when compared to C. guianensis and its inhibition of A. flavus, A. niger and F. oxysporum suggested synergistic actions of the substances in the control of phytopathogenic fungi.

Finding new applications for the essential oils (EOs) of the branches and leaves of Aniba species represents a valuable strategy for the adoption of correct management of the crown and to help make Aniba plantations economically valuable. We report here the antifungal activity of the EO from Aniba rosaeodora Ducke against plant pathogenic fungi. The present study investigated the chemical variability and antifungal effect of EO from A. rosaeodora harvested during the wet and dry seasons in the Amazon region. The volatile content obtained from the aerial parts by hydro-distillation was analyzed for its chemical composition by gas chromatography–mass spectrometry (GC–MS). Furthermore, a broth and agar dilution method was used to determine the antifungal activity against phytopathogens. Quantitative and qualitative variations in composition among the EOs were detected. Linalool was a major component in the oil of leaves and branches from both periods. Quantification using an external standard showed a higher concentration of linalool in the wet season (74.4 ± 3.9% in leaves and 81.8 ± 5.7% in branches) than in the dry season (47.5 ± 2.2 in leaves and 49.2 ± 1.6% in branches). The EOs were toxic to all phytopathogens analyzed, displaying superior inhibitory activity toward Colletotrichum guaranicola, with inhibition zone diameters ranging from 15.2 ± 1.2 to 21.3 ± 1.7 mm and IC50 values of 0.578 to 2.094 μL mL−1. Interestingly, the EOs collected during the wet season were effective in reducing the vegetative growth of phytopathogens, providing evidence for the involvement of linalool in the inhibitory effect.

Isoprene and other plastidial isoprenoids are produced primarily from recently assimilated photosynthates via the 2-C-methyl-D-erythritol 4-phosphate (MEP) pathway. However, when environmental conditions limit photosynthesis, a fraction of carbon for MEP pathway can come from extrachloroplastic sources. The flow of extrachloroplastic carbon depends on the species and on leaf developmental and environmental conditions. The exchange of common phosphorylated intermediates between the MEP pathway and other metabolic pathways can occur via plastidic phosphate translocators. C1 and C2 carbon intermediates can contribute to chloroplastic metabolism, including photosynthesis and isoprenoid synthesis. Integration of these metabolic processes provide an example of metabolic flexibility, and results in the synthesis of primary metabolites for plant growth and secondary metabolites for plant defense, allowing effective use of environmental resources under multiple stresses.

Background: Choosing the correct species and fertilization treatments is a determining factor in the success of forest restoration. Methods: A field study was conducted in a degraded area near the Balbina hydroelectric dam in Amazonas State (AM), Brazil, to evaluate two hypotheses: (i) leguminous tree species exhibit differences in growth, leaf nutrient content, and photosynthetic nutrient use efficiencies; and (ii) differences in these characteristics depend on the fertilization treatments to which the species have been subjected. Dipteryx odorata, Inga edulis and Schizolobium amazonicum were subjected to the following treatments: (T1) unfertilized control; (T2) post-planting chemical fertilization; (T3) post-planting organic fertilization and (T4) combined chemical and organic post-planting fertilization. Results: In general, I. edulis had the highest absolute growth rate of biomass under all of the fertilization treatments. I. edulis and S. amazonicum showed the highest growth rates under the T4 treatment. D. odorata showed the greatest responses under the T2 and T4 treatments. Native leguminous trees with higher photosynthetic performance and better nutrient use efficiency exhibited greater growth and biomass production. Conclusion: The results suggest that an adequate balance between leguminous species selection and fertilization will aid in the success of forest restoration in Amazonia.

Brazil plans to construct many new hydroelectric dams in the Amazon region. The new conditions of flooding promoted by reservoirs can alter photosynthetic processes, and the study of physiological responses of trees can be used for selected suitable species to reforest these altered areas. The present study analyzed changes in pigment content and photosynthetic performance in flood-tolerant and flood-intolerant species that are common in the floodplains along the Uatumã River and on islands in the reservoir of the Balbina Hydroelectric Dam. Their photosynthetic responses were tested using chloroplast pigment content and chlorophyll a fluorescence. Flooding caused a significant reduction in pigment content in all of the three flood-intolerant species and in one of the seven flood-tolerant species studied. Flood-tolerant species were unaffected and neither a change in their chlorophyll contents nor a decrease in the efficiency of energy use in the photosynthetic process was observed. From chlorophyll a fluorescence transients (OJIP transients) was calculated the performance index (PIABS), a parameter derived from the OJIP transient by means of the JIP-test (translation of original fluorescence measurements into biophysical expressions quantifying the stepwise flow of energy through photosystem II). This parameter was a very sensitive indicator of the physiological status of trees under field and was shown to be a particularly sensitive indicator of stress tolerance in flood-intolerant species during inundation, whereas flood-tolerant species had only minor reductions in their photosynthetic performance. We suggest that tree species selection for reforestation around reservoirs can benefit from species-specific measurements of photosynthetic response using the JIP-test.

Increasing areas of Amazonian forest are coming under flood stress due to dam construction and greater variability in river flood levels due to climate change. The physiological responses of Amazonian trees subjected to flooding are important to understand the consequences of these changes. Irradiance response curves for photosynthesis obtained from ten tropical tree species growing in flooded areas were used to fit three empirical models. The study was done in floodplains along the Uatumã River, both upstream and downstream of the Balbina Hydroelectric Dam in Brazil’s state of Amazonas (01°55′S; 59°28′W). Ten species were studied. Models compared were: non-rectangular hyperbola, rectangular hyperbola, and exponential. All models were quantitatively adequate for fitting the response of measured data on photosynthesis to irradiance for all ten species in the non-flooding and flooding periods. Considerable variation was found among the model estimates of maximum photosynthesis (P nmax), dark respiration (R d) and apparent quantum yield of photosynthesis (α). For photosynthesis, the two hyperbolas overestimated P nmax while EXP presented more realistic values. For estimating R d, RH presented the most realistic values. To avoid unrealistic value estimates of R d, we recommend adding measured R d values to the regressions. The results suggest that the EXP model presented the most realistic P nmax and α values, and, in spite of less accuracy in fitting photosynthetic irradiance curves than the RH model, it can be recommended for accessing the information used in photosynthetic irradiance curves for the leaves of tropical trees growing in Amazonian floodplains or in areas that are artificially flooded by dams.

Pasture soils in the Amazon become unsustainable after a short period of use, typically being replaced by emergent secondary vegetation (capoeira). The aim of this research was to investigate the photosynthetic capacity and water use in the most common tree species (Vismia japurensis, Vismia cayennensis, Bellucia grossularioides, Laetia procera, and Goupia glabra) in successional chronosequence. This study was carried out in secondary vegetation area with ages that vary between 1 and 19 years. Responses of gas exchange were determined during different periods of precipitation. The gas exchange decreased with advancing age of the vegetation (1–19 years), except for G. glabra. Negative relationships of P Nmax as a function of aging observed for V. japurensis, V. cayennensis, B. grossularioides, and L. procera exhibited r 2 equal to 0.59, 0.42, 0.33, and 0.58, respectively. The species of Vismia showed higher values for photosynthetic parameters in relation to other species across the chronosequence. Overall, there were differences in gas exchange only for some species between the different periods of precipitation. Therefore, our results suggest a distinct pattern of photosynthetic responses to species in early succession. Light decrease can exert a decisive role to reduce the photosynthetic rates in secondary succession species. On the other hand, the results of WUE showed weak evidence of changes for the species during dry and rainy periods in the abandoned pasture in central Amazonia.

In an experimental site for reforestation of degraded area, three-year-old plants of Bertholletia excelsa Humb. & Bonpl. were subjected to different fertilization treatments: T0 = unfertilized control, T1 = green fertilization (branches and leaves) and T2 = chemical fertilization. Higher net photosynthetic rates (P N) were observed in T1 [13.2±1.0 μmol(CO2) m−2 s−1] compared to T2 [8.0±1.8 μmol(CO2) m−2 s−1] and T0 [4.8±1.3 μmol(CO2) m−2 s−1]. Stomatal conductance (g s), transpiration rate (E) and water use efficiency (WUE) of individuals of T1 and T2 did not differ significantly, however, they were by 88, 55 and 63%, respectively, higher in T1 than in the control. The mean values of variable fluorescence (Fv), performance index (P.I.) and total chlorophyll [Chl (a+b)] were higher in T1. Our results indicate that green fertilization improves photosynthetic structure and function in plants of B. excelsa in young phase.

The success of initial tree seedling establishment is related to the capture and use of primary resources such as light and nutrients. The selection of tree species with a greater potential to assimilate carbon and capacity to efficiently utilize nutrients and light would facilitate the revegetation of degraded areas, primarily where irradiance is high and soil nutrient availability low. We analyzed soil physical and chemical characteristics, survival, growth, photosynthesis, chlorophyll a fluorescence, leaf macro- and micro-nutrient content and photosynthetic nutrient use efficiency in young tropical tree species planted in degraded areas in central Amazonia. The species studied were: Bellucia grossularioides, Bombacopsis macrocalyx, Cecropia ficifolia, Cecropia sciadophylla, Chrysophyllum sanguinolentum, Eugenia cumini, Inga edulis and Iryanthera macrophyla. C. sanguinolentum, a late secondary species, exhibited the lowest survival rates, except when compared with B. grossularioides and C. sciadophylla. Photosynthesis varied between 34 and 264 nmol g−1 s−1 for the eight species; species of Cecropia had photosynthetic values eight times greater than C. sanguinolentum. For the photochemical efficiency of photosystem II, C. sanguinolentum presented the highest degree of photoinhibition as a result of an inefficient use of excess irradiance. Leaf macronutrient concentrations varied from 16 to 29, 0.4 to 1.0, 6 to 13, 7 to 22, 1.6 to 3.4 g kg−1 for N, P, K, Ca and Mg, respectively. For photosynthetic nutrient use efficiency, in general, the two species of Cecropia exhibited the highest values, while C. sanguinolentum presented the lowest macronutrient use efficiency. The two species of Cecropia had photosynthetic nitrogen use efficiency seven times greater than C. sanguinolentum. On these highly degraded soils we found that pioneer trees (Cecropia) are better able to colonize than species from other successional stages. Trees on these degraded soils are primarily limited by P or micronutrients. Despite the remove of the O horizon, N does not appear to limit photosynthetic activity. From this we conclude that species of Cecropia possess ecophysiological mechanisms associated with carbon assimilation and nutrient use that determines success in early establishment and has potential to recuperate degraded areas, especially when compared to C. sanguinolentum. Early secondary species such as I. edulis and E. cumini could also be used with success in forest plantings to recuperate degraded areas when selecting for species, (1) efficient in the utilization of excess energy for photosynthesis, (2) efficient in the use of limited soil nutrients and (3) with high survival and growth rates.
