Rootstock affects graft success, growth and physiological parameters of grape varieties (Vitis vinifera L.)

A field experiment was conducted to study the effect of different rootstocks (Dogridge, 110R, 140Ru and 1103P) on growth and physiological parameters in Crimson Seedless, Manjari Naveen and Nanasaheb Purple. Growth parameters such as trunk girth, number of canes and leaf area showed the significant difference while stock:scion ratio, graft success showed non-significant difference among the cultivars. However, physiological parameters such as transpiration rate and assimilation rate showed non-significant difference in Crimson Seedless and Manjari Naveen while in Nanasaheb Purple it showed significant difference. Stomatal conductance showed the significant difference in all the three cultivars. The present study revealed that among all rootstocks, Dogridge and 1103P performed well for vegetative growth and physiological parameters. | Rootstock affects graft success, growth and physiological parameters of grape varieties (Vitis vinifera L.)
