摘要
研究各浓度芒萁水提液对受体植物玉米 ,绿豆和白菜若干生理特性的影响。实验表明 ,各浓度芒萁水提液可降低受体植物种子活力 ;测定淀粉酶活性、可溶性糖含量、NR活性、叶绿素含量及根系活力等生理指标表明 ,对玉米低浓度促进高浓度抑制 ,而对绿豆和白菜则呈现明显抑制作用。
Dicranopteris pedata forms consocies in commuities.The allelopathy is an important factor except for the greater capability in the struggle for existence.This paper studies the effects of extracts from Dicranopteris pedata on several physiologic characteristics of plant acceptors.The results show that the extracts can decrease the seed vigor of all plant acceptors.ln other physiologic indexes,extracts show singinificant inhibition on Dhaseolus aureus and Brassica pekinensis,low density extracts show promting function and high density extracts express inhibitory function on zea mays.
