摘要
利用同位素示踪法研究了根系导入生长素和玉米素对玉米籽粒形成期和灌浆期光合产物输出及分配的影响。结果表明 ,根源的生长素和玉米素显著促进光合产物从饲喂功能叶向外的输出 ,提高光合产物向产量器官的分配率 ,减少了光合产物在茎节的分配率 。
Effects of IAA and zeatin introduced through secondary roots on translocation and partitioning of photosynthate in maize during kernel formation stage and grain filling period was studied in a experiment by using isotopic tracer technique. It was shown that IAA and zeatin coming from root enhanced the export of labelled assimilate from functional leaf greatly. With the application of IAA and zeatin on secondary root in maize plant, the partioning rate of photosynthate to reproductive organs was increased, while that to stem decreased. Furthermore, the content of soluble carbohydrate in sink organs was improved also.
