【摘要】 试验筛选几种药剂对毛豆进行喷施处理,测定其在水分胁迫下对毛豆幼苗有关营养生长指标和生理指标影响,结果表明:几种药剂处理后均可比对照促进苗增高、增加叶面积、促进根系的生长、增加根系活力、抑制丙二醛增生、降低细胞膜透性和提高叶绿素含量、相对含水量、脯氨酸含量、细胞保护酶的活性等,有力地增强了毛豆幼苗对水分胁迫的抵抗能力,从叶面喷施几种药剂对毛豆的生长及生理指标的影响进行综合分析可知,几种药剂以油菜素内酯为最优、其它依次为三十烷醇、黄腐酸盐、爱多收、绿风95等处理更多还原

【Abstract】 Effects of several kinds of drugs on the vegetative growth indexes and the physiological indexes of Maodou under water stress were studied in the experiment.The results showed: promotion seedling growth, increasing the root activity,the chlorophyll content,the proline content, relative water content and protective enzyme activity ,suppressed MDA content, reduced the cell permeability compared with control after treated with these drugs, and thus effectively enhanced the resistance of the seedling to the abnormal environment. From the Comprehensive analysis on the effects of these drugs on the vegetative growth indexes and the physiological indexes, BR treatments worked best, it was successively TA, FA, Atonk and Lufeng 95.更多还原
