embryogenic callus initiation from anther and whole flower explants in four grapevine cultivars including flame seedless, shahroodi, perlette and red sultanina cultured on piv and harst nutrient media was studied. results showed that whole flower explants of ‘flame seedless’ cultured on piv medium had the most potential for callus production. later callus were transferred onto ges1ca medium for...

seedless grapes are widely grown all over the world. embryo rescue technique proved to be able to overcome the problem of embryo abortion in seedless grape breeding program. since, the efficiency of this technique is not desirable, so a lot of efforts have been done in different directions in order to improve this technique. this study was conducted in two separate experiments in which chlormeq...

Understanding how nutrients accumulate and change throughout the developmental stages according to BBCH scale can be a very effective technique for developing fertilization programmes high-quality, marketable grape production. Accordingly, macro- micronutrient concentrations at different growth were analyzed two commercial cultivars, viz., “Anab-e-Shahi” “Perlette”, by using an extended scale. ...

In this study the effects of plant growth regulators including; GA3 (0 and 50 mg/l) and ethephon (0 and 500 mg/l) were studied on the quality properties of two grape cultivars (Perlette and Yaghuti). At the harvest time, some physicochemical characteristics such as fruit cluster weight, fruit diameter, length, volume and L/D ratio, flesh firmness, fresh weight, TA, pH, TSS and fruit color were ...
