The grape berries due to containing organic acids, sugars, aromatic compounds, phenolic compounds (including anthocyanins, flavanols, flavonols, stilbenes (resveratrol)), tannins, and oil in the pulp, skin, and seed have numerous health benefits for human health. In this study, we investigated genetic and phytochemical characteristics of four famous grapevine cultivars (Shiraz, Sirch, Panje Aro...

meiotic study was performed in 11 brassica napus cultivars considering chiasma frequency anddistribution, chromosome pairing, as well as the occurrence of b-chromosomes and their effects on chiasmafrequency. such cytogenetic pairing, along with agronomic characteristics, may be used in planninghybridization among the b. napus cultivars. all the cultivars studied possessed n=19 chromosome number...

The chemical composition and radical-scavenging activity of wood samples from 10 main Spanish olive cultivars were studied. The wood samples were collected during the pruning works from trees growing under the same agronomical and environmental conditions. The 10 ethyl acetate extracts were submitted to HPLC-DAD/ESI-MS analysis to determine the phenolic constituents. Seventeen compounds were id...

The pistachio green stink-bug, Brachynema germari Kolenati (Hem.: Pentatomidae), is an important pest of pistachio in Iran. In this research, the effects of four commercial pistachio cultivars that are commonly grown in Iran including Kaleghochi, Ahmadaghaii, Ohadi and Akbari were evaluated on the biology (developmental time, mortality rate, longevity) and demographic parameters of <em...

The genetic diversity among Tunisian pomegranate cultivars has been investigated. Using universal primers, the random amplified polymorphic DNA (RAPD) method was used to generate banding profiles from a set of twelve cultivars. Data was then computed with appropriate programs to construct a dendrogram illustrating the relationships between the studied cultivars. Our data proved the efficiency o...

knowledge of environmental and ecological factors as well as growth and development pattern of fruit trees is an important task in orchard management and fruit industry. in addition, determination of growth pattern is an important aspect in the orchard management system. in this research, the total photosynthesis rate and growth pattern was measured in nine asian pear cultivars. experiment was ...

The contents of kaempherol, quercetin and L-ascorbic acid in sea buckthorn berries were measured at different maturation stages using High Performance Liquid Chromatography (HPLC) methods. The content of ascorbic acid decreased over time with significant differences between sampling dates for the five cultivars studied. The mean decrease was 25% in 19 days, from 1.48 to 1.10 g kg. Quercetin dec...

in order to study of genetic diversity and similarity among four native olive cultivars including ‘mari’, ‘zard’, ‘shengeh’ and ‘rowghani’, these cultivars were evaluated in five regions including ali abad, gilvan, tarom, manjil and jamal abad at 2012-2013. there was a significant difference among studied individuals. the correlation coefficient analysis among studied traits showed that there w...
