The performance of Superior grapevines grafted onto three rootstocks namely SO4, Freedom and 1103 Paulsen cultivated under covered and uncovered conditions were evaluated during 2015 and 2016 seasons. Data obtained showed that grapevines under plastic cover recorded the highest leaf area, chlorophyll content in leaves and macroelement content in leaf petioles, in addition, it has a significant effect on yield and berry quality. Concerning the effect of rootstocks, the differences in productivity and grape quality between the tested rootstocks were significant and it was obvious that Freedom in comparison with 1103 Paulsen and SO4 significantly increased vines vegetative growth especially under protected cultivation.
