14C-乙烯示踪试验结果表明,小麦孕穗期植株对乙烯的吸收、运转和分布规律,与对乙烯利的吸收、运转和分布规律基本一致,均向穗部集中,在小麦剑叶上涂以14C-乙烯利后,穗部释放14C-乙烯的高峰发生在第六天,此高蜂期正值小麦幼穗迅速发育时期,与乙烯利杀雄的“靶期”相吻合,认为乙烯利对小麦杀雄,是由其释放乙烯而起作用,剑叶涂14C-乙烯利15天后,雄蕊中的放射性主要分布在RNA蛋自和糖类中,雌雄蕊的HCl提取物中具放射性的物质不是未分解的乙烯利,表明乙烯利进入小麦体内能被代谢、转化,并参入其他成分之中。
The results of 14C-ethylene tracing showed that the absorption, transport and distribution of ethylene to the plants at the booting stage were basically the same as those of the absorption, transport and distribution of ethephon. After 14C-ethephon, the peak of 14C-ethylene release from ear was observed on the sixth day. The high-bee period coincided with the rapid development of young wheat, which was consistent with the target period of ethephon killing. Wheat kill male, by its release of ethylene to play a role, the flag leaf coated 14C-ethephon 15 days later, the radioactivity in stamens mainly in the RNA egg and carbohydrates, the stamen HCl extract with radioactive material is not Undissolved ethephon, indicating that ethephon into wheat can be metabolized, transformed, and into the other components.
