comparison and grouping of 32 grape cultivars and genotypes by using 61 traits including; 5 phenological and vegetative characters, 41 traits related to fruit and amount of resveratrol in 15 parts of plant was done according to grape descriptor and related methods. according to the results some traits such as spikelet weight, berry color, length of peduncle, length of berry tail, weight and len...

to evaluate effects of gibberllic acid, gridling, berry and bunch thining and their combination on fruit maturity, berry and bunch characteristics of grape cv. yaqooti an experiment was carried out using randomized complete block design with three replications in kavar, shiraz, iran, in 2010-2011 growing season. each experimental plot consisted of three vines. treatments included: t1: gibberlli...

a number of grapevine cultivars have female flowers and for better fruit set, they need pollinizer. single planting of these cultivars leads to severe decrease in fruit set. this research was carried out to investigate the effect of cross pollination with four grape cultivars (askari, rish baba, bidane sefid and tabarze sefid) on fruit set, bunch weight, berry per cluster, average weight of 20 ...

every year large amounts of grapes are stores in normal and cold rooms to offer off-season of grapes to the market which based on several reasons their quality and weight greatly decreases. therefore, in order to decrease the post harvest losses of grapes and selection of suitable cultivars for long time storage, this study was conducted in two experiments, one in a factorial experiment based o...

Forecasting the grape yield of vineyards is of critical importance in the wine industry, as it allows grape growers to more accurately and confidently invests in capital equipment, negotiate pricing, schedule labour and develop marketing strategies. Currently, industry standard forecasts are generated by manual sampling of bunch weights, grape size, grape numbers and seasonal predictions which ...

The influence of GA3 application on the fruit quality and productivity of cane pruned Thompson seedless was evaluated. Four treatments applied were: GA3, Girdle, GA3 + Girdle and control with no GA3 and no girdle were used. GA3 or GA3 + Girdle berries resulted in heavier berries, hastened berry diameter, and produced larger berries in comparison to the control grapevine trees. In addition, bunc...

Grape (Vitis vinifera) yield is largely dependent on the fecundity of the cultivar. The average number of inflorescences per shoot (i.e. shoot fruitfulness) is a trait related to fecundity of each grapevine. Berry number and weight per bunch are other features affecting grape yield. An ovule-specific auxin-synthesizing (DefH9-iaaM) transgene that increases the indole-3-acetic acid content of gr...

grapevine is one of the very important fruit crops in iran the fruit of which is used as table grape and/or raisins. in this study, some genetic parameters (phenotypic and genetic correlation, heritability and repeatability), of some important traits in table grape (date of ripening, weight, length and width of berry as well as attachment to cluster strength) were evaluated. results showed high...
