紫茎泽兰的水浸提液对干香柏和藏柏种子萌发的影响

Effect of Water-extracted Solution of Eupatorium Adenophorum Spreng on Seeds Germination of Cupressus torulosa and Cupressus duclouxiana Hichel

将在常温下浸泡48 h紫茎泽兰(Eupatorium adenophorumSpreng)的根、茎、叶、花各部位的水浸提液原液,以自来水作为对照,利用培养皿滤纸法研究紫茎泽兰各部位提取液对干香柏和藏柏种子萌发的影响,实验结果表明,紫茎泽兰各部位水浸提液对干香柏和藏柏种子萌发都具有化感克异作用,高浓度水浸提液的抑制作用强于低浓度的抑制作用.

48-hour-water-extracted solution at a natural temperature respectively from the root,stem,leaf and flower of Eupatorium Adenophorum Spreng was sprayed on the seeds of Cupressus torulosa and Cupressus duclouxiana Hichel making contrast of tap water to see the effect of the solution on seeds germination.The result showed that the water-extracted solutions had a negative effect on seeds germination,and the denser solutions had stronger negative effect than the thinner solution.
