摘要
在柿属砧木资源调查研究基础上，选择７种１２个类型，对其种子、幼苗形态、生长特性进行了详细研究。砧苗年生长动态可用Ｌｏｇｉｓｔｉｃ曲线模拟，全年以８月上旬至９月下旬的生长量最大。不同砧木的出苗率、年生长量有极显著差异，以浙江柿１号、君迁子等生长最快，根系最发达。同种不同类型间生长特性也有明显差异，在作砧木利用时而加以选择。
ABSTRACT Twelve rootstock types belonging to 7 persimmon species were studied interms of their respective seed characters，and seedling morphology and growth habits．Re-suIts showed that the annual growth process of all rootstock seedlings can be well modelledby Logistic curves，with the maximum growth commencing from early August to lateSeptember．The rate of emergence and the annual increment varied markedly with the root-stock，and Diospyros glaucifolia（No.1）and D，lotus（No.9）shdwed the greatest growthwith the best-developed root system. Growth differed considerably even in the samespecies；therefore，it is all the more necessary to make selections on the rootstocks in prac-tice.KEY WORDS Diospyros spp；Rootstock；Biological characteristics.
