| 摘 要： | 试验筛选三十烷醇、油菜素内酯、爱多收、绿风95、黄腐酸盐等几种药剂对早熟毛豆进行喷施处理,测定其在水分胁迫下对其幼苗某些生长、生理指标的影响及抗性评价。结果表明,采用几种药剂处理后,与相应的对照相比可促进苗增高、扩大叶面积、增加干物质的积累、促进根系的生长、提高根系活力、抑制丙二醛增生、降低细胞膜透性和增加叶绿素含量、脯氨酸含量、细胞保护酶的活性等,增强毛豆幼苗对水分胁迫逆境的抵抗能力;在逐渐干旱胁迫下,5种药剂处理以油菜素内酯为最好;在持续淹水胁迫下,5种药剂处理以绿风95为最优。

| Abstract: | Effects of several types of drugs(TA,BR,ATONK,LUFENG95,FA) on some growth and physiological indexes of Glycine max and resistance evaluation of them under water stress were studied.The results showed that they promoted seedling growth,increased root activity,chlorophyll content,proline content,and protective enzyme activity.They suppressed MDA content and reduced cell permeability compared with the controls and thus effectively enhanced the resistance of seedlings to abnormal environments.A comparison of the five kinds of drug treatments showed that BR treatments worked best under drought stress,while Lufeng95 treatments worked best under waterlogging stress. |
