一,植物激素与高粱的生长发育早在1936年借助燕麦试法便已测出高粱芽鞘基部含有丰富的生长激素物质。迄今在植物体内已发现的生长素(Auxin),赤霉素(Gibberellin),细胞分裂素(Cytokinin),乙烯(Ethylene)和脱落酸(Abscisic acid)等五大类内源激素,在高粱体內都有存在。它们是高粱生长发育过程中必需的特殊物质。高粱植株体內的生长素主要是吲哚乙酸
First, the growth and development of plant hormones and sorghum as early as 1936 with the method of oat has been measured sorghum bud sheath base rich in growth hormone substances. So far in plants have found five major endogenous hormones auxin (Auxin), gibberellin (Gibberellin), cytokinin (Cytokinin, Ethylene and Abscisic acid), both in sorghum There is. They are sorghum growth and development of the necessary special material. The main auxin in sorghum plants is indole acetic acid
