Abstract: The growth and leaf mineral content of "Xinhuicheng"and " Jincheng" (Citrus sinensis) young plants on different rootstocks were studied, using virus-free rootstocks and scions kept in isolation. Significant effects of the rootstocks were found on the growth and leaf mineral content. The greatest growth was generally seen on"sough"lemon (Citrus limon)and "Zhuluan" ," Xiaohongcheng" (Citrus aurantium) ,with lesser growth on trifoliata orange (Poncirus trifoliata)and "Banggan" ,"Xing-shansuancheng" (Citurs aurantium)rootstocks. The effect of each rootstock on growth and leaf mineral content of "Xinhuicheng"and "Jincheng"was almost similar. The amount of growth showed a curvilinear relationship with leaf nitrogen content supplied by the rootstocks.
