摘要

The effect of rootstocks on leaf P content was non-significant, whereas, leaf N, K, Ca, and Mg were significantly affected by the rootstocks. Maximum leaf N, K, Ca and Mg contents were recorded in leaves of trees raised on rootstock EMLA-106 and lowest on rootstock EMLA-26. Cultivars also differed significantly in their leaf N, P, K, Ca and Mg contents. Highest leaf K, Ca and Mg contents were found in cultivar Red Chief, whereas minimum in Silver Spur. Maximum leaf N was found in cultivar Oregon Spurwhereas, P was maximum on Well Spur. Maximum leaf water potential was observed in the trees raised on EMLA-106 and lowest on EMLA-26. There were also significant effects of cultivars on leaf water potential. Oregon Spur exhibited maximum leaf water potential whereas, lowest incultivar Well Spur.
