摘　　要：以秦美猕猴桃（ Ａｃｔｉｎｉｄｉａ ｄｅｌｉｃｉｏｓａ Ｃ．Ｆ．Ｌｉａｎｇ ＆ Ａ．Ｒ．Ｆｅｒｇｕｓｏｎ ｃｖ．Ｑｉｎｍｅｉ）４ ａ 生树为试材，研究了不同时期生成的１４Ｃ－ 同化物的贮藏动态及再利用规律。结果表明，新梢迅速生长期和缓长期生成的１４Ｃ－ 同化物主要在地上部贮存，新梢第２ 次生长高峰期和采果后生成的１４Ｃ－ 同化物主要在根部贮藏。全年生成的１４Ｃ－ 同化物对次年新生器官建造均有一定作用，但新梢缓长期以后生成的１４Ｃ－The storage rage and retranslocation of 14 C-assimilates in kiwifruit trees (Actinidia deliciosa) was studied. The results showed that:① 14 C-assimilates accumulated from spring to summer would be reserved in branches and that accumulated in fall could be mainly reserved in roots. ② In the following spring, 14 C-assimilates accumulated in the whole growing season played a certain role in the structure of new organs,but those accumulated in summer and autumn were more important.
