3个多花黑麦草品种化感作用研究
Allelopathy of three varieties of Lolium multifolorum
摘要
Abstract
The biological detection techniques were used to determine the allelopathy effectiveness of leaf and stem extracts from three varieties of Lolium multifolorurn on Sardi 10 of Alfalfa. The results of this study showed that the allelopathy effectiveness of three varieties of L. multifolorum on alfalfa were different. The extract from Barextra leaf encouraged Sardi 10 seeds to germinate. The 10. 0% and 7.5% concentrations of extract of Barmega leaf inhibited Sardil0 seeds to germinate. This study also found that the allelopathy effectiveness of extracts from stem and leaf was different, indicating that the stem extracts of Jumbo and Barextra inhibited Sardi 10 seeds to germinate while the leaf extracts of Jumbo and Barextra encouraged Sardi 10 seeds to germinate. Different concentrations of extracts showed different allelopathy effectiveness, indicating that the 10. 0% concentration extracts of L. multifolorum showed a positive effectiveness and the 5. 0% concentration extracts of L. multifolorum showed a negative effectiveness on seed germination, root growth and seedling fresh weight of Sardi 10 of Alfalfa.关键词
