摘要
本文用^(14)CO_2示踪法,研究葡萄幼树碳素同化物分配输出特性,结果表明,碳素同化物质分配有季节特点。生长前期主要集中供给地上部各新生器官;中期地上部与地下部分配比较均衡;后期则稳定回流。
The characteristics of the dlistribution and exportation of carbonassimilates in the young grape vine were studied by means of ^(14)CO_2 tracer method from 1986 to 1987. The results indicated that carbon assimilates in the young grape vine were characterized by seasonal distribution. They were mainly concentrated to supply the new organs aboveground din the early stage, distributed harmoniously to the aboveground and underground parts in the middle stage, and transported reversely and stored mainly in the roots, stems and buds, eto. in the latter stage.
