| 摘 要： | 目的]研究紫茎泽兰不同组织根、茎、叶水浸提取液对2种农作物玉米、水稻化感作用及对受试农作物生理指标的影响,以探讨化感物质作用机制。方法]采用培养皿滤纸法测定不同浓度根、茎、叶水浸提液对受试种子萌发率和幼苗生长影响,并检测受试农作物生理指标丙二醛（MDA）含量、过氧化物酶（POD）活力的变化。结果]紫茎泽兰根、茎、叶水浸提液对受试玉米、水稻的发芽率和幼苗根长、株高均有不同程度的影响,使受试农作物幼苗体内丙二醛（MDA）含量增加、过氧化物酶（POD）活性呈现先增加后降低趋势。结论]紫茎泽兰不同组织水提液对受体植物的种子萌发、幼苗生长过程均具有明显的抑制作用,其茎的化感敏感效应大于根、叶,水提液抑制受试农作物光合效率,提高了幼苗体内的MDA含量,并降低了POD酶活性。
