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...

For vector-borne diseases, interactions between vector, host, and pathogen can influence patterns of disease spread. In particular, previous studies suggest that host genotype may influence disease dynamics because of differences in susceptibility to the pathogen and, therefore, subsequent vector transmission efficiency from these plants. We tested this hypothesis by using the pathogenic bacte...

Global warming will significantly affect grapevine growth and development. To analyze the effects of high temperature on leaf tissue structure grapevines in field, 19 representative cultivars were selected from germplasm resources garden Turpan Research Institute Agricultural Sciences, XAAS. Twelve indexes leaves, including thickness upper epidermis (TUE), palisade (TPT), vein (LV), spongy (TST...

flame seedless is one of the most important and commercial table grape cultivar that is used for breeding program due to its specific characteristics of fruit high production. in order to breed new seedless grape cultivars and with considering importance of selecting seedless varieties as a female parent to increase the production rate of seedless offspring in a breeding cycle, embryo rescue te...
