Disappearance of old cultivars, including dry and snap bean (Phaseolus
vulgaris L.) has been accelerated in last five to six decades, which mainly
led to great genetic impoverishment. For all the humanity and its future,
particularly is important the maintenance and evaluation of old cultivar?s
seeds. The research presented in this paper has been conducted on the
territory of southwestern Fruska gora Mt. Of the collected samples of field
and vegetables crops, as well as wild plants on the mountain, 13 accessions
of snap bean and 21 accessions of dry bean have been analyzed in this paper.
Seed color, seed shape, 1000-seed mass and phaseolin type was determined for
all the accessions. Seeds of collected bean and snap bean accessions were
predominantly white and cylindrical in shape. Mass of 1000 seeds ranged
between 104,90 g and 634,96 g. T phaseolin type dominated, while S type of
phaseolin was present in six bean and in two snap bean accessions. [Projekat

Eight different Serbian genotypes were analysed for their polyphenol, carotenoid, vitamin C content and evaluated for their antioxidant properties. The highest content of biologically important carotenoids such as lutein (4.58 mg/10 g), lycopene (160.64 mg/10 g) and b-carotene (189.64 mg/ 10 g) were detected in the genotype S606. Rutin was the most abundant phenolic compound in all tastes samples, but its content is highest in the genotype S615 (1424.30 mg/100 g dw). All tomato samples were the great source of vitamin C, where the sample S615 stood out (68.54 mg AA g À1 of dw). Their content of antioxidant compounds suggested that genotypes S606 and S615 showed the best antioxidant potential. Principal component analysis (PCA) and Partial least squares (PLS) were applied to analyse results. The results obtained in the present study could be of considerable interest for breeding programmes wishing to select tomato genotypes with high biological and nutritional properties.
Garlic was examined in field experiments conducted in central Serbia (Belgrade). Spring garlic was examined. The objective was to examine the effect of plant density on photosynthesis productivity (LAR-Leaf Area Ratio, NAR- Net Assimilation Rate) and the yield of garlic. The analysis involved the following plant densities: 300 (G1), 450 (G2), 600 (G3), 750 (G4) and 900 (G5) thousand plants ha-1. The garlic exhibited better results in denser crop establishment. It is clearly indicated by the yield of garlic attained in the experiments. Average yield rates range from 5.6 (G1) to 12.5 t ha-1 (G5). The results demonstrate that the garlic should be grown in high density establishment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
