Salinity Soil Effects on Yeild, Fruit Quality and Mineral Composition of Superior Seedless Grapevines Grafted on Some Rootstocks

Ola A. Ahmad

Background and Objective: This investigation to study the evaluation of superior seedless grape cultivar grafted on Paullson 1103, Salt Creek and freedom grapevine rootstocks to soil salinity compared to own rooted superior seedless cultivar. Methodology: This study was conducted to estimate: Vegetative growth parameters, chemical analysis, yield and berry characteristics and antioxidant isozymes electrophoresis. The present data were statically analyzed by using new LSD method at 5% level. Results: The results showed that, superior grape cultivar grafted on three rootstocks gave the best results as compared to own rooted superior grape cultivar for three consecutive seasons. However, superior seedless grape cultivar grafted on Salt Creek rootstock had the highest percentage of bud burst and fruitful buds, improved the best vegetative growth parameters, increment depth of the roots and their distribution in the soil profile. Cane content of total carbohydrates, leaf content of total chlorophyll and mineral content were increased and leaf prolin content, sodium and chloride were reduced. Additionally, it had a positive impact on the yield and berry quality attributes. Vine grafted on Paullson 1103, rootstock had a moderate effect for these parameters while, superior seedless grafted on freedom rootstock came the next. As regards to isozymes (peroxidase and polyphenyl oxidase), there were differences found in banding pattern density in freedom rootstock with high density banding patterns compared with Paullson1103 and superior seedless cultivar which appeared with moderate density in banding patterns. On the other hand, polyphenyl oxidase electrophoresis analysis represent no differences in banding patterns density among all rootstocks. Conclusion: Superior seedless grafted on Salt Creek, Paullson 1103 and freedom grape root stocks were more tolerant to soil salinity than superior seedless cultivar on own rooted root stock, vines grafted on Salt Creek was the most tolerant one.
