Sweet pepper leaves were dripped by 14c - glucose and 14c - sucrose , the tracer experi ment indicated : exogenous sugars could be translocated to every part of plant after being absorbed by leaf , but the centralized distribution to some exuberant organs in growth such as fruit , young stem and leaf , had no relation between organ dry weight and distributive amount ; the absorptivity of 14c - glucose by leaf was higher than that of 14c - sucrose 用含有14c标记的外源糖(葡萄糖和蔗糖)点滴青椒叶片，示踪试验表明：外源糖被叶片吸收后可运转到植株的各个部位，但集中向果实，幼嫩的茎、叶等生长比较旺盛的库性器官分配，其分配量与器官干重无关；青椒对外源葡萄糖的吸收率高于蔗糖。
