磨盘柿叶片、果实及萼片中酚类物质的动态变化初报

A Study on the Dynamic Changes of Phenolic Compounds in Leaves, Fruit, and Calyx of Mopan Persimmon (Diospyros kaki L. f.cv. Mopan)

磨盘柿(DiospyroskakiL.f.cv.Mopan),是中国北方主要栽培的涩柿品种。在此,对其叶片、果实及萼片中的酚类物质含量在多个发育时期进行了测定,结果表明:在生长期内,柿萼片中的酚类物质含量呈上升趋势,与果实酚类物质含量变化规律完全不同;叶片的酚类物质含量均高于果肉的酚类物质含量;结果梢叶片与营养梢叶片酚类物质的含量变化不同,8月下旬以前,结果梢叶片的值大于营养梢叶片的,8月下旬以后,前者又小于后者。

Mopan Persimmon is the major cultivar of astringent persimmon in northern China. This experiment followed the contents of phenolic compounds in leaves, fruit flesh, and fruit calyx in different growing stages of Persimmon, and the results showed that： the content of phenolic compounds in fruit calyx increased constantly, this change pattern was fully different with that of the fruit flesh： the phennlic compounds in the leaves was always higher than that in the fruit flesh; the differences existed in the contents of phenolic compounds between branches with fruits August, the contents value of branches with fruits was higher and branches without fruit： Before the end of than the value of branches without fruit, after the end of August, on the contrary, the contents value of branches with fruits was lower than the value of branches without fruit.
