| 摘 要： | 采用二种外源生长调节剂(GA、IAA)和二种处理方法(喷施和浸根),研究了不同生长调节剂对铝胁迫紫花苜蓿(Medicago sativa L.)恢复生长,以及对铝胁迫下紫花苜蓿生长的影响.结果表明,IAA和GA对铝胁迫紫花苜蓿恢复生长过程中,紫花苜蓿根长、根重和地上生物量均有明显的促进作用(P＜0.05),但IAA的促...

| Abstract: | The effects of plant growth regulators(GA and IAA) and their exogenous applicative ways(spraying and dipping) to alfalfa on the growth and recovery of the Al-stressed alfalfa were studied in this paper.The results showed that the exogenous IAA significantly increased the root elongation,root weight and above-ground biomass of alfalfa during the recovery growth of Al-stressed alfalfa(P<0.05),while the GA also showed the similar effect,but the effect was lower than that of IAA.Meanwhile,exogenous IAA signific... |
