It was hypothesized that stachyose is translocated by squash because stachyose is supplied to the phloem loading system by the photosynthetic system. To test this hypothesis, (14)CO(2) was supplied to squash leaves. The nonphosphorylated sugars containing (14)C were studied. A large proportion of (14)C appeared in stachyose very early in the time sequence, tending to confirm the hypothesis.
人们假设蜜二糖是通过南瓜被转运的,因为蜜二糖是由光合作用系统供应给韧皮部装载系统的。为了验证这一假设,(14)CO2 被供应给南瓜叶片。研究了含有(14)C 的非磷酸化糖。在时间序列的早期,大量(14)C 出现在蜜二糖中,这倾向于证实了这一假设。
