杀雄剂易被小麦吸收,并分布在植株的不同部位,以穗部为多,尤其是雄蕊,它能引起植株形态学、细胞学以及生理生化的变化。雄蕊出现核酸尤其是 RNA 与蛋白质合成的下降,脯氨酸含量减少,以导致雄性不育。本文亦讨论了乙烯利杀雄的作用形式,主要是释放乙烯,并认为乙烯利参与了物质的代谢. Kill maleicide is easily absorbed by wheat and distributed in different parts of the plant, with more spikes, especially stamens, which can cause morphological, cytological and physiological and biochemical changes in plants. Stamens appear to have decreased synthesis of RNA, especially RNA and protein, and reduced proline content to cause male sterility. This article also discusses the action form of ethephon, which is mainly to release ethylene, and that ethephon is involved in the metabolism of matter.
