摘　　要：选择了12种柿砧木类型,对其生物学特性进行了观测。结果表明,不同砧木在种子大小、出苗率、幼苗形态、年生长量等有明显差异,油柿、野柿种子较大。浙江柿1号、君迁子等种子较小,出苗率高,年生长量大,根系发达。砧苗年生长呈明显的节律变化,在6月下旬至7月上旬,8月中旬至9月中旬出现2个明显的生长高峰,尤以秋季生长量最大。同一物种不同类型或产地间的砧木生长特性有明显差异,在作砧木利用时需加以选择。To observe biological characters of twelve varieties of persimmon rootstock, the results showed that different rootstock had significant differences in seed size, emergence rate, seeding morphology and annual increment. The seed size of Diospyros glaucifolia （No.1） and D. lotus were smaller than D.oleifera Cheng and D. kaki var. silvestris Mak, but the emergence rate and the annual increment were higher than the others, and the root system were stronger. The annual growth rhythm of rootstock was obviously, two significant growth peaks appeared in late June to early July and mid August to mid September, especially, the maximum growth appeared in autumn. Growth differed considerably even in the same species, therefore, it is necessary to make selections on the rootstocks in practice.
