Sucrose-(14)C was fed to the leaf blades of squash plants (Cucurbita pepo L. var. melopepo torticallis Bailey) for 30 or 60 minutes. Petioles of treated plants were cut into sections and extracted. The majority of the (14)C within the petiole was in sucrose rather than stachyose, the sugar that is transported by the squash plants when (14)CO(2) is supplied. This indicates that the phloem loading system of squash plants is not the system that specifies which sugar is transported.
将蔗糖-（14）C 喂给南瓜植物（Cucurbita pepo L. var. melopepo torticallis Bailey）的叶片 30 或 60 分钟。处理过的植物叶柄被切成段并进行提取。叶柄中的大部分（14）C 是蔗糖而不是棉子糖，当供应（14）CO（2）时，这是南瓜植物运输的糖。这表明南瓜植物的韧皮部装载系统不是指定运输哪种糖的系统。
