- 摘要:
- 为实现对入侵植物的有效防治与转化利用，以云南地区常见的紫茎泽兰和牛膝菊2种入侵植物为试材，研究了2种植物的根、茎、叶、花各部位的组织浸泡后获得的水提液对犬齿复活线虫的毒杀活性。结果表明：紫茎泽兰和牛膝菊不同采集部位水提液均存在不同程度的毒杀线虫活性，且与水提液浓度和处理时间呈正相关；紫茎泽兰不同组织部位线虫毒杀活性强弱顺序依次为花>叶>茎>根，牛膝菊为茎>叶>花>根。
- Abstract:
- Taking Eupatorium adenophorum and Ealinsoga parviflora as the source materials，the control and inversion utilization of invasive plants were studied.The extracts of roots,stems,leaves and flowers were tested to study the resistance of the two plants to Panagrellus redivivus.The results showed that the different extracted parts all had a nematicidal activity，and it was in direct proportion to the concentration and acting time.The nematicidal activity of Eupatorium adenophorum was followed by flowers>leaves>stems>roots.The nematicidal activity of Galinsoga parviflora was followed by stems>leaves>flowers>roots.
