The health and yield of grapes are affected by the microorganisms associated with grapevine. diversity present on wine grape varieties is well defined whereas, information table remains scarce. In study, culture-dependent method was used to isolate microbes surface commercial white seedless cultivar, Thompson Seedless at different stages berry development. microbial load increased as progressed...

Downy mildew ( Plasmopara viticola ) and powdery Erysiphe necator are the most common economically significant fungal diseases in vineyards. The task of this work is to study genotypes new promising hybrid forms table grapes for presence resistance genes downy Rpv10 Rpv3 Ren9 using DNA-markers. was carried out on grape hybrids under working names Agat dubovskiy, Akelo, Arabella, Artek, Dubovski...

Morphological evaluation of large progenies is a problem in plant breeding programs, because the need for skilled labor capable characterizing various descriptors number individuals ripening simultaneously. In addition, maintenance field involves an unsustainable consumption resources that could be reduced. Marker-assisted selection (MAS) offers possibility accelerating process with consequent ...

The aim of this study is to optimize extraction parameters of phenolic compounds from one variety of Algerian table grapes. The effect of different solvents: distilled water, acetone (20, 40, 60 and 80%), methanol (20, 40, 60 and 80%) and ethanol (20, 40, 60 and 80%), temperature (25, 40, 50, 60 and 70°C), time (30, 60, 90 and 120 min) and four successive extractions were tested. It was found t...

Humic acids are the most active components of soil organic matter and have been shown to have an hormone-like activity thus stimulating plant growth. The objective of this work was to verify the quantitative and qualitative yield responses of the table grape cv. Italia after the application of a humic acid at various phenological stages. The humic acid used in this study has been extracted from...
