Abstract: In order to investigate the effect of nutrient contents on the growth potential of litchi cultivars.In this study,two weak growth potential cultivars and seven strong growth potential cultivars were as plant materials to determine the stem,leaf morphological character-istics and the contents of leaf organic and inorganic nutrient.The results showed that plant height,shoot length,pitch spacing,leaf width,leaf length and leaf area in the two weak growth potential cultivars were smaller than those in the seven strong growth potential cultivars.And the contents of soluble sugar,starch and protein of weak growth potential cultivars higher than strong growth potential cultivars,while potassium,manganese and copper content were lower than strong growth potential cultivars.In addition,the plant height was negatively correlated with the starch content of leaves in litchi,and was negatively correlated with total carbon and nitrogen content,but was positively correlated with the content of amino acid.The leaf area was positively correlated with the contents of amino acids and phosphorus,and was positively correlated with zinc content.
