植物激素在棉株生长和发育的作用研究方面,特别在应用生长抑制,如2-氯乙基三甲基氯化铵(CCC)和2-氯乙基-N-二甲基氯化肼(CMH),控制棉株的生长,应用赤霉素及类似生长素2,4-D和萘乙酸,防止棉铃脱落以及探索棉铃发育过程中内源激素的变化规律方面等,国内外已有很多报道。本文主要报道植物激素在棉花开花、结铃中的作用。 Plant hormones in cotton growth and development of the role of research, especially in the application of growth inhibition, such as 2-chloroethyl trimethyl ammonium chloride (CCC) and 2-chloroethyl-N-dimethyl hydrazine chloride CMH), controlling the growth of cotton plants, applying gibberellin and auxin-like 2,4-D and naphthaleneacetic acid, preventing cotton bolls from falling off and exploring the changing rules of endogenous hormones during the development of cotton bolls . This article mainly reports the role of plant hormones in cotton flowering and boll.
