细菌发酵液对小白菜种子萌发的影响

Effect of Bacterial Fermentation on Seed Germination of Chinese Cabbage

[目的]研究不同浓度的细菌发酵液对小白菜种子发芽及其成苗的影响。[方法]用5株细菌发酵液对小白菜种子进行浸种和发芽试验,并测定各项指标。[结果]细菌发酵液对小白菜种子发芽率、发芽指数起抑制作用,原液抑制作用最强。发酵液对小白菜种子芽长、幼苗鲜重皆表现为抑制作用,1000倍稀释液表现为明显的促进作用。细菌发酵液对幼苗干重、活力指数起促进作用,原液的促进作用最强。[结论]适宜浓度的细菌发酵产物能明显提高小白菜种子的活力,促进小白菜的生长。

[Objective] Five kinds of bacteria fermentation liquid were applied in Chinese cabbage to study the effects on sprout and seedling.[Method] Soaking and germination test were used.[Result] Germination rate and germination index were inhibited by bacteria fermentation liquid,and stock solution had the strongest inhibitory action.Stock solution,10 times and 100 times dilution of the cabbage showed inhibitory to seed sprout and seedling fresh weight,while the 1 000-fold presented a significant role in promoting seedling dry weight and vigor index.[Conclusion] Products of optimal concentration promoted vigor and growth significantly.
