摘要: 以5年生‘天红2号’苹果/SH40/八棱海棠为试材,对其上部、中部和下部新梢叶片进行13C标记处理,研究其产生的13C同化物的运输分配去向。结果表明:新梢的13C自留量(自身叶片 + 自身新梢)以上部新梢中最高,为91.00%,中部新梢中次之,为79.34%,下部新梢中最小,为67.39%;新梢向其它器官提供13C同化物能力大小的顺序为:下部新梢 > 中部新梢 > 上部新梢;其中向根系的13C分配率差异最为显著,由大到小依次为下部新梢 > 中部新梢 > 上部新梢;上部和中部新梢输出的13C同化物均有超过50%分配到地上部,分别为87.42%和59.79%,而仅有12.58%和40.21%分配到地下部,表现为以向地上部运输为主,而下部新梢分配到根系的13C同化物达到了75.53%,以向根系运输为主。

Abstract: The 5-year-old apple trees(Tianhong 2/SH40/Malus robusta Rehd.)were divided into three parts(the upper part,the middle part and the lower part),and those three parts(new shoot)were labeled with 13C to study about the fate of 13C-assimilates in plant. The results showed that the self-retention of the upper new shoot was the highest(91.00%),that of the middle new shoot was in the second place(79.34%),that of the lower new shoot was the lowest(67.39%). The supply capacity of those three parts to other organs was manifested as the lower part > the middle part > the upper part. The distribution of root was very obvious,manifested as the lower part > the middle part > the upper part. More than 50% 13C-assimilates was allocated to aboveground in the trees that were labeled upper new shoot and middle new shoot,were 87.42% and 59.79%,respectively,only 12.58% and 40.21% were transported to root,mainly transported to above-ground. The distribution of 13C-assimilates in root was labeled lower parts plants reached 75.53%,mainly transported to underground(root).

Key words: apple, different parts of new shoot, 13C-assimilate, transport, distribution
