The recovery of inaperturate pollen from functionally female flowers in archaeological layers opens the question of a possible pollen-based discrimination between wild and domesticated Vitis vinifera in prehistoric times. Pollen analysis applied to archaeology has not routinely considered the existence of pollen dimorphism in Vitis, a well-known trait in the field of agrarian studies. Therefore, the inaperturate shape of grapevine pollen is ignored by studies on the archaeobotanical history of viticulture. In this paper we investigate pollen morphology of the domesticated and wild subspecies of V. vinifera, and report the first evidence of inaperturate Vitis pollen from an archaeological site. We studied exemplar cases of plants with hermaphroditic flowers, belonging to the subspecies vinifera with fully developed male and female organs, cases of dioecious plants with male or female flowers, belonging to the wild subspecies sylvestris and cases of V. vinifera subsp. vinifera with morphologically hermaphroditic but functionally female flowers. The pollen produced by hermaphroditic and male flowers is usually trizonocolporate; the pollen produced by female flowers is inaperturate. This paper reports on the inaperturate pollen of Vitis found in an archeological site of the Po Plain, Northern Italy. The site dated to the Bronze Age, which is known to have been a critical age for the use of this plant with a transition from wild to domesticated Vitis in central Mediterranean. Can the inaperturate Vitis pollen be a marker of wild Vitis vinifera in prehistoric times? Palynology suggests a possible new investigation strategy on the ancient history of the wild and cultivated grapevine. The pollen dimorphism also implies a different production and dispersal of pollen of the wild and the domesticated subspecies. Grapevine plants are palynologically different from the other Mediterranean “cultural trees”. In fact, Olea, Juglans and Castanea, which are included in the OJC index, have the same pollen morphology and the same pollen dispersal, in wild and domesticated plants. In contrast, the signal of Vitis pollen in past records may be different depending on the hermaphroditic or dioecious subspecies.

A liquid chromatography coupled-tandem mass spectrometry method was developed and validated for the determination of free soluble phenolic compounds in eight ancient varieties of wheat (Triticum sp. pl.), notably Autonomia, Gentil rosso, Inallettabile, Leone aristato, Mentana, Poulard di Ciano, Risciola and Terminillo. Trace compounds such as two conjugated flavones, vitexin (17.13-34.32 µg/kg) and isovitexin (9.76-30.01 µg/kg), were also determined. Poulard di Ciano, presumably an autochthonous wheat of the Reggio Emilia province (Northern Italy), showed a peculiar quali-quantitative phenolic profile (7097.03 µg/kg total phenolic sum and 1.97 hydroxycinnamic acids sum to hydroxybenzoic acids sum ratio) along with a tetraploid genome. Terminillo, Risciola, Gentil rosso, Mentana, and Leone aristato showed a hexaploid genome and high concentrations of phenolic compounds (ranged from 6796.12 to 7605.78 µg/kg), also in comparison with two modern varieties of bread wheat, Bolero and Blasco. The targeted metabolomic approach proved to be effective to determine some secondary metabolites of wheat. The richness in phenolic compounds combined with high rusticity and adaptability to marginal soils showed by ancient wheat varieties make them suitable for sustainable agricultural and organic cultivation.

The properties of building materials relevant to their thermal or aesthetical performance can be seriously influenced by the colonization of external surfaces by microorganisms. Deterioration phenomena due to biological aggression cause the loss of energy performance of solar reflective materials because of the decrease of solar reflectance. Bio-deterioration also affects cultural heritage, damaging the aesthetic appearance and thus the historic value. In order to investigate the consequences of biological aggression in short times, an accelerated test method based on a laboratory-reproducible set-up is proposed. Specific and controlled environmental conditions are chosen to accelerate as much as possible biological growth on building materials. In this regard, a reproducible bio-ageing protocol has been outlined and it allows a set of materials to reach an advanced bio-aged level in a short time (8 weeks or less). This test method is aimed to comparatively evaluate different materials under a given set of ageing conditions. Through surface, microstructural and chemical analysis, the evolution of the materials’ properties after ageing is investigated. Attention is also paid to bacterial and algal growth rate by analysing time-progressive images.

Among the main issues concerning building materials, in particular outdoor ones, one can identify the colonization by microorganisms referred to as biological aggression. This can affect not only the aesthetical aspect but also the thermal performance of solar reflective materials. In order to improve the reliability of tests aimed to assess the resistance to biological aggression and contextually reduce the test duration, an accelerated test method has been developed. It is based on a lab reproducible setup where specific and controlled environmental and boundary conditions are imposed to accelerate as much as possible biological growth on building materials. Due to their widespread use, polymeric materials have been selected for the present analysis, in the aim of reaching an advanced bio-aged level in a relatively short time (8 weeks or less) and at the same time comparatively evaluate different materials under a given set of ageing conditions. Surface properties before, during and after ageing have been investigated by surface, microstructural and chemical analyses, as well as by examination of time progressive images to assess bacterial and algal growth rate.

Quercus robur L. was micropropagated by axillary bud proliferation testing two different shoot culture systems: (i) on gelled medium in Microbox (plastic vessel with a strip for ventilation) and (ii) in liquid culture in PlantformTM bioreactor (a temporary immersion system). Two different conditions of temporary immersion were assessed: 12 min/8 h (Plantform 1) and 8 min/16 h (Plantform 2). The effect of the two culture systems was evaluated also during subsequent rooting phase, carried out on gelled medium. Finally, the influence of the different culture conditions on leaf structure was considered, taking also into consideration the micromorphological characters of young leaves from in-field-grown oaks. Nodal segments, excised from established in vitro shoots and cultured on modified Woody Plant Medium, showed a higher Relative Growth Rate in Plantform than in Microbox, but culture conditions provided in Plantform 1 favored shoot and leaf hyperhydricity. Shoots cultured in Microbox or Plantform 2 presented the same percentage of rooting after their transfer on gelled rooting medium. Leaves developed in the two different microenvironments had large stomata with elliptical shape, which indicates good functionality, and formed hairs, and epicuticolar waxes. These leaf features are considered to provide a good adaptability to ex vitro conditions.

Self-pollination conditions have been recorded frequently in local populations of the genus Epipactis, and structural modifications have sometimes been reported, supporting taxonomic recognition of new species. As part of a survey of gynostemium micromorphology of Italian Epipactis populations, we studied an Apennine population of Epipactis microphylla (Ehrh.) Sw. a species listed as autogamous but with residual allogamous characters. In this population we observed the tendency to perform pre-anthesis cleistogamy. However, self-pollination was not a consequence of modification in column morphology. Cryptic pollen germination occurred in anther thecae or in the clinandrium, bypassing any contact with the receptive stigma. Pollen germination started from the distal pool of the pollinium, close to the rostellum-viscidium, suggesting that the rostellum-viscidium may have a function in promoting pollen-tube growth. Germinated pollen was exposed at the anthesis.

Eggplant (Solanum melongena L. cv. Violetta lunga 2) cotyledon expiants grown on hormone-free medium (controls) or on medium containing either naphthaleneacetic acid alone (root forming) or in combination with zeatin riboside (shoot forming) showed minor differences in free polyamine titres during culture. In contrast, conjugated polyamines (particularly those in the trichloroacetic acid-soluble fraction) accumulated only in hormonetreated explants, but not in controls. The extent and the temporal changes in soluble-conjugate levels differed between root-forming and shoot-forming expiants; in the former, accumulation began earlier (within 1 day of culture) and reached the highest levels. In both organogenic programmes, maximum conjugate accumulation occurred just before and during organ emergence. Adventitious roots and shoots were formed along the cut surfaces. The regions closest to these (“borders”) displayed a significantly higher ratio of conjugated to free spermidine and/or putrescine than the nonorganogenic regions (“centres”) of the explant. Ornithine decarboxylase activity was higher than arginine decarboxylase activity both in control and hormone-treated explants. However, both activities increased markedly on day 2 of culture in the presence of hormones. Thereafter ornithine decarboxylase activity remained high in shoot-forming explants, but not in root-forming ones. Putrescine oxidising activity was also enhanced by exogenously supplied hormones starting from day 4 of culture. This activity remained high up to day 12 in the presence of auxin plus cytokinin, whereas it peaked on day 6 in auxin-treated explants. Spermidine oxidising activity was the only enzyme activity which was consistently higher in controls than in hormone-treated tissue. Differences between the two organogenic programmes with respect to temporal changes in polyamine content, and putrescine biosynthetic and oxidative activities are discussed in relation to the timing of organ formation. The latter was monitored both histologically and macroscopically.
