前言为调节苹果座果率,必须控制乙烯的释放。乙烯利降解后释放乙烯,利用乙烯利可减少座果。此外,如萘乙酸及其氨化物之类的化学疏除剂也能促进乙烯的释放。相反,利用一种乙烯生物合成抑制剂AVG可以提高座果率和产量。这种药剂可能对初始座果率和‘六月落果’有明显影响,对几种化学疏除剂有颉颃作用。
Introduction To regulate the fruitsetting rate of apple, we must control the release of ethylene. Ethylene degradation after the release of ethylene, the use of ethylene can reduce the fruit. In addition, chemical sparing agents such as naphthaleneacetic acid and its amides can also promote the release of ethylene. In contrast, AVG, an ethylene biosynthesis inhibitor, can increase fruit set rate and yield. This agent may have a significant effect on the initial fruitsetting rate and the ’drop in June’ and has an antagonistic effect on several chemical sparing agents.
