甜菜作物的生长速度强烈地受其生长中心(叶片扩展,块根与侧根间和块根与蔗糖贮之间同化产物分配等)的影响,而植株各生长中心间同化物分配可由各自运转和分配同化物的能力大小来测得。然而,这些运转和分配的细胞学生物化学基础以及控制机制还不太清楚。为探明这些生理现象,本文作者比较研究了甜菜两种类型的根中蔗糖合成酶的特性和酶 The growth rate of beet crops is strongly influenced by their growth centers (leaf expansion, assimilation product distribution between tuberous roots and lateral roots and tuberous roots and sucrose storage), and the assimilation of the assimilate between the growth centers of the plants can be controlled by their respective functioning and distribution assimilates The size of the ability to measure. However, the basics and mechanisms of cytology of these operations and distributions are not yet known. To identify these physiological phenomena, the authors compared the characteristics of sucrose synthase and enzyme
