The effect of spraying GA3 on some qualitative and quantitative characteristics of grape Var. Bidaneh Sefid
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 12
Abstract
In our country, one of the most important fruit is grape. Cultivation and production of grape has very long history. Since area under cultivation and production rate of grape compare to other horticultural products has been very considerable, and also it uses in the different ways in local and foreign, there for , economically, it is one of the rare products which could be export as the non-oil goods. This study was investigated to evaluate the effect of the using time of spraying gibberellic acid on some qualitative and quantitative characteristics of grape Var. Bidaneh(Seedless) Sefid by using a completely randomized design and factorial experiment with three replications and three plants in each plot. Treatment included, 0, 30 ppm GA3 on the tail of grape before and post- blooming. Measured traits included ,the panicle weight, panicle length, grain weight, Total Dissolved Solids, acidity, and pH of juice. Result showed thinning clusters was significantly greater at 30ppm GA3 before blooming ,whereas , spraying GA3 in post-blooming, increase the cluster length, grain weight, grain diameter, TSS and pH of the juice. Therefore, treatment with GA3 for thinning clusters before blooming and using GA3 to increase the quantity and quality of grain in post-blooming, was recommended.
