以外来入侵植物黄顶菊(Flaveria bidentis)为试材,研究了日光温室盆栽条件下黄顶菊与黄瓜混作对黄瓜株高、干鲜重、叶绿素含量、根系活力、过氧化物酶(POD)活性和过氧化氢酶(CAT)活性、丙二醛(MDA)含量的影响,以及黄顶菊浸提液对黄瓜种子萌发的影响。结果表明:黄顶菊对混作的黄瓜株高和鲜重增长都有明显的抑制作用;生长在黄顶菊附近的黄瓜的根系活力、叶片叶绿素含量及POD活性、CAT活性均
Flavria bidentis was used as experimental material to study the effects of flaveria bidentis and cucumber mixed with cucumber on plant height, dry and fresh weight, chlorophyll content, root activity, peroxidase (POD) activity and peroxidation (CAT) activity and malondialdehyde (MDA) content of cucumber seedlings and the effects of Flaveria bidentis extracts on the germination of cucumber seeds. The results showed that: Flaveria bream on the cucumber plant height and fresh weight growth were significantly inhibited; growth of cucumber in Huangtiao near the root activity, leaf chlorophyll content and POD activity, CAT activity were
