| 中文摘要: |
| 研究不同浓度的蜜环菌Armillaria mellea发酵液对油菜籽萌发、幼苗生长的影响。结果表明，发酵液在油菜籽萌发过程中对种子的发芽势影响显著，对最终种子发芽率影响不大；发酵液具有促进幼苗伸长，抑制根生长的作用；随着发酵液浓度的升高，幼苗的成活率呈下降趋势；发酵液对幼苗生产量的影响表现为低促高抑，低浓度促进生产量的增加，高浓度下幼苗的生产量随着浓度的升高而降低。通过对蜜环菌化感作用的检测，蜜环菌发酵液在油菜籽的发芽势、苗伸长、根生长及幼苗生产量等方面均具有化感作用。 |
| 英文摘要: |
| Effects of different concentration of Armillaria mellea fermentation filtrate on the rapeseed germination and seedling growth were investigated. The results suggested that the filtrate had a remarkable effect on the germination vigor. The filtrate doesn’t influence the germination rate. It can promote the growth of seedlings and inhibits the growth of root. Elevated filtrate can reduce the survival rate. The filtrate stimulating effect at low concentration and inhibitory effect at high concentration on seedling yield. The inhibition level increased with the concentration of the fermentation filtrate. The filtrate has an remarkable allelopathy effects on the germination vigor, the growth of seedlings and root, and seedling yield of rape. |
