【摘要】 以君迁子和美国柿为对照,在果实发育中期,对41个柿品种、45个样品的果实内单宁细胞,进行了组织学镜检。结果表明,一般甜柿较涩柿的单宁细胞数目少,个小,横径/纵径指数小。从果实顶部到基部,单宁细胞的横径变化不显著,但纵径从小到大,横径/纵径指数由大到小,甜柿一般较涩柿变化明显。作为砧木的君迁子和美国柿,果实内单宁细胞数量为普通柿的3～7倍,横径/纵径指数在0.7以上,但果实不同部位差异很小。更多还原

【Abstract】 Tannin cells of persimmon fruits of 45 samples from 41 varieties in their middle stage development were observed histologically with Dateplum Persimmon and American Persimmon as the control. The results showed that Tannin cells of sweet persimmons were smaller in numbers, size and cross diameter / longitudinal diameter ratio. From the top to the base in fruit, there was no much variation in cross diameter of Tannin cells, but its longitudinal diameter became from small to large, and the cross / longitudinal diamter indexes were from large to small. Sweet persimmons change more greatly than puckey varieties. Also, the numbers of Tannin cells of Dateplum persimmon and American persimmon frenquently used as stocks were 3~ 7 times as many as other varieties. Cross / longitudian indexes are were over 0.7, but there are very small differences in different parts of the fruit.更多还原
