摘　　要：以部分中国原产甜柿为试材,通过对可溶性单宁含量测定和单宁细胞切片观察发现,在果实接近成熟时,‘罗田甜柿’、‘宝盖甜柿’、‘秋焰甜柿’(鄂柿1号)果肉中单宁细胞较小,所占比例较低,可溶性单宁含量低于0.2%。因此确认供试中国甜柿种质属于完全甜柿。In this research, some Chinese non-astringent persimmons were used as materials to identify the property of natural loss of astringency. By the determination of the soluble tannin content and the observa- tion of the tannin ceils in fruits flesh, it was found that size of tannin cell shrank, relative area oppcupied by tannin cell in per unit area flesh was also lower, and soluble tannin content was under 0. 2%. It was suggested that ‘Luotian-Tianshi＇ , ‘Baogai-Tianshi＇ and ‘ Qiuyan-Tianshi＇ （ Eshi 1 ） all belong to pollination constant non-astringent persimmon （PCNA）.
