Abstract:The morphologic feature，growth and development，leaf screen and leaf biomass of four Ginkgo caltivars in China were studied in this paper，which were Kuijin，Mating 5#， Jiafushou and Dongfinghuang．Leaves of Ginkgo are categorized：fan shape．Semicircle shape and the heart shape．The heterophylly of Ginkgo is related with age of shoots and location of leaves growth．The phyUotaxis of cutivars are proved to be 3/8．The annual dynamic change in leaf length，leaf width，petide length，leaf area，dry and fresh weight of leaf can be expressed。“S”-shaped curves．Water content in leaves sharply declines as the leaves growth period prolongs．Length of long shoot is 583cm，numbers of leaves are 402， leaf area is 9735cm2，fresh weight of leaves is 355g，leaf axca index is 2.58 for a 3-year- old young grafted tree．
