| 摘 要： | 利用乙酰胆碱 (Ach)、微丝解聚剂 (LatA)和维管束固定剂 (FAA)处理萝卜的韧皮部 ,以叶片中可溶性糖和淀粉含量以及14 C 同化物从叶片中的输出量为指标 ,研究 3种药剂对韧皮部同化物运输的调控作用。结果表明 ,低浓度的Ach可有效地促进14 C 同化物向肉质根的运输 ,而LatA和FAA处理则有效抑制14 C 同化物向肉质根的运输。 |

| Abstract: | The petiole phloem of Raphanus sativus L. is treated with the medicaments of acetycholine (Ach, the expansionist material of protoplasm), latrunculin A (LatA, the dissolubility of microfilament) and FAA (the regularization of phloem). The effects of treatments are measured by the accumulated content of dissoluble sugar and starch in the leaves, and 14C-labelled assimilates. The regulating role of three medicaments on the translocation of assimilates in the phloem of Raphanus sativus L are investigated. The results indicate that low Ach improves assimilates translocation while LatA and FAA inhibit it in petiole phloem of Raphanus sativus L. = |
