几种植物生长调节剂对苄嘧磺隆胁迫下烟草的生长作用
The Effects of Some Plant Growth Regulators on Nicotiana tabacum Affected by the Residue of Bensulfuron-methyl
摘要
Abstract
Bensulfuron-methyl (BSM)is a kind of herbicide of low toxicity,high efficiency and safety,but the residue of herbicide still can cause hazardous to succeeding crops in the field due to the intensive utilization. It was analyzed in this research that the effects brought by some kinds of plant growth regulators on the tobaccos affected by the residue of BSM,and the time of symptom-emergency,the growth vigor as well as the growth-recovering were compared between different treated and control groups. Symptoms caused by BSM on tobaccos cannot prevented by variety kinds of plant regulators and inhibitors i.e. jasmonic acid (JA),salicylic acid (SA), salicylhydroxamic acid (SHAM),diethyldithiocarbamic acid (DIECA). However,SA can improve the growth of affected plants,and the ratio of recovered herbicide-treated plants sprayed with SA was the highest. To the contrast,the growth of the herbicide-treated group couldn't gain any improvement sprayed with SHAM and DIECA, which was even weaker than the herbicide-treated tobaccos sprayed with solutions,and the recovered ratio was zero. Thus we found that SA can improve the growth of the plants suffered from the residue problem brought by BSM significantly. But the method of SA-application should be improved to gain a better results.关键词
