棉花蕾铃脱落是棉花生产中普遍存在的问题,现今采用的陆地棉(G.hirsutum)脱落率达60—70％。因此,研究蕾铃脱落的规律,找出原因,并提出减少脱落的措施,是提高棉花产量的有效途径。 国外关于棉花蕾铃脱落的研究,早在二十年代开始。工作比较稳定,主要是在蕾铃脱落的生理机制方面进行了长期的研究。近十几年来,以内源和外用激素为主要内容,
Cotton buds shedding is a common problem in cotton production. Today, G. hirsutum sheds 60-70%. Therefore, studying the law of the falling buds, finding out the reasons and putting forward the measures to reduce shedding are the effective ways to increase the cotton yield. Foreign studies on cotton buds fall off as early as the 1920s. The work is relatively stable, mainly in the long-term research on the physiological mechanism of the fall of the bell. Over the past decade, with endogenous and topical hormones as the main content,
