The increased interest in organic tomatoes production demands breeders to develop new cultivars, which besides suitability in low-input production system and marketable quality, have to exhibit high nutritional value, including health-promoting compounds. In this respect, this paper aimed to assess and compare the nutritional value of four Romanian tomato cultivars, two with determinate growth (‘Arge7 11’ and ‘Arge7 123’) and two with indeterminate growth (‘Costate 21’ and ‘:tefane7ti 22’), created and recommended for organic production in open field and protected cultivation. The tomato cultivars were laid out in a high plastic tunnel crop and the tomato fruits were evaluated as chemical composition, being determined the following parameters: moisture, ash, soluble solids, pH, acidity and content in some antioxidant compounds, such as vitamin C,polyphenols, flavonoids, anthocyanins, lycopene and =-carotene. Considering some chemical parameters important in revealing tomato flavor, such as soluble solids, pH and acidity, ‘:tefane7ti 22’ cultivar showed the best ratio among them. The differences in antioxidant composition among cultivars were not statistically significant (P>0.05) for most of the analyzed parameters, with the exception of lycopene content which showed significant variation. Thus, ‘Costate 21’ showed the highestamount of lycopene within indeterminate cultivars (17.49 mg 100 g-1 FW), while ‘Arge7 11’ showed the highest amount of lycopene within determinate cultivars (13.92 mg 100 g-1 FW). According to the nutritional value of cultivars assessed in this study, ‘Costate 21’ is the best recommendation for greenhouse cultivation while ‘Arge7 11’ is the best recommendation foropen field cultivation.

The walnut leaves and the green walnut husk are been widely used in folk medicine. These vegetal materials have been reported as a source of bioactive molecules such as the phenolic compounds. In this research, there were analysed different quality parameters afferent to several walnut varieties, harvested from the germplasm collection located at S.C.D.P. Vâlcea, Romania. Romanian cultivars ‘Jupâneşti’, ‘Valrex’ and ‘Valmit’ and French one ‘Franquette’ were analyzed. The variation in bioactive compounds content from the walnut leaves and walnut husk at different developmental stages (from June to September) was investigated. The results showed that the content in polyphenols, flavonoids and tannins has significantly increased until the ripening stage, after that a decrease of the values of these parameters follows. Greater values of the three parameters were also observed at walnut leaves and green walnut husk of cultivars attacked by walnut blight, caused by the bacterium Xanthomonas arboricola pv. juglandis (Xaj). The findings of this study reveal the mode of variation in the content of polyphenols, flavonoids and tannins during the growing season of the walnut leaves and green walnut husk, emphasizing also the influence of Xaj. The results obtained demonstrated the potential of the walnut leaves and the green walnut husk as an economical source of antioxidant and antimicrobial agents. ********* In press - Online First.

The research was carried out on 23 host plants and the attack of 32 fungal pathogens was identified. The identified pathogens were classified by attack incidence value (F%) into main pathogens, secondary pathogens and potential pests. The host plants that were attacked by key pathogens were chrysanthemum, snapdragon, marigold, yarrow, yucca and rose. The host plants that were attacked by pathogens from the secondary group were peony, sedge, oxeye, hydrangea, hyacinth, queen of the night, sage and cloves. Attack of potential harmful pathogens has been recorded on gladioli, tulips, snapdragons, chrysanthemums, marigolds, pansies, dahlias, hydrangea, petunia, cock's crest and primroses. The species in which the simultaneous attack of three key pathogens was registered was the rose.

The pathogens Alternaria solani and Fusarium oxysporum f. sp. lycopersici are of significant interest from a pathogenic perspective in the context of tomato cultivation. This study focuses on evaluating the fungicidal and fungistatic effects of different synthetic substances and natural compounds on the development of these two investigated pathogens. The fungicidal agents employed comprised fosetyl aluminum at a concentration of 0.3%, azoxystrobin at 0.2%, and metiram at 0.3%, while the natural extracts investigated included those derived from European birthwort, celandine and sage, each tested at concentrations of 0.5%, 2%, 9%, and 15%. The assessment of mycelial growth inhibition was conducted utilizing Vincent’s formula. Additionally, the total polyphenol content (TPC) within the extracts was determined via the Folin-Ciocalteu spectrophotometric method in accordance with Frum et al. (2022). Furthermore, the antioxidant capacity of the extracts was evaluated using the DPPH radical scavenging method (2,2-diphenyl-1-picrylhydrazyl) and high-performance liquid chromatography (HPLC). Our research findings yielded noteworthy results, specifically, extracts derived from sage and celandine, particularly when present at a concentration of 15%, exhibited a fungistatic effect. This effect was particularly remarkable when compared to the performance of the synthetic fungicide azoxystrobin at a concentration of 0.2% when challenged with the Alternaria pathogen. These results suggest the potential utility of sage and celandine extracts as eco-friendly alternatives for mitigating fungal pathogens in tomato crops, warranting further investigation and consideration within agricultural practices.

The research was carried out on 10 varieties of roses grown in the "Alexandru Buia" Botanical Garden. During the growing season, field ratings were made on the frequency (F%) and intensity (I) of attack in order to calculate the degree of attack (GA%). The determinations were made at three different times, namely in June, September and October.Depending on the average values of the degree of attack at the three determinations, it was found that two varieties behaved as sensitive with attack degree values of 8.06% and (Ajsa) and 10% (Terracotta), respectively, and eight varieties as very sensitive with values between 15.83% (Velvet Fragance) and 35% (Melina).The quantification of the effect of the attack of the pathogen Diplocarpon rosae Wolf on the monitored rose varieties revealed changes in some biological characteristics related to the ratio of foliole length and width to the same parameters in the case of unattacked organs. The most severe loss was due to their response to attack by the pathogen Diplocarpon rosae Wolf
