most sweet cherry (prunus avium l.) cultivars are self-incompatible and have problems of ‎fertilization and fruit set. to produce commercial crops they need compatible and suitable ‎pollinizers. the compatibility of “zarde daneshkadeh”, “protiva”, “sorati lavasan”, “haj-yosefy” ‎and “meshkin shahr” cultivars with “shoa-o-saltaneh” as seed parent studied in a randomized ‎complete block design (r...

in order to evaluation of squash (cucurbita pepo) seed yield per fruit and its relations with other characteristics of fruit include: length, diameter, length: diameter ratio (fruit shape), flesh thickness, thousand seed weight and fruit weight, an experiment was conducted using 24 accessions of squash as a randomized complete-block design with three replications. morphological traits were eval...

The water needs for tomato crops are very high and could limit the viability of cultivation in semiarid environments. There is no agreement among works on irrigation regarding sensibility flowering period. In addition, there a lack studies about effects stress fruit cluster development under severe stress. aim this work was to evaluate effect rehydration during development. experiment conducted...
