- 摘要:
- 以草酸青霉菌HB1发酵液为研究对象,通过发芽试验,探究其对黄瓜、辣椒及白菜3种蔬菜种子发芽率、幼苗生长及其根耐性指数的影响,以期为设施蔬菜的高质量育苗提供参考依据。结果表明:草酸青霉菌HB1发酵液稀释106倍用于处理黄瓜和辣椒种子,促生的各指标达到最高,其中发芽率分别达到100.00%、98.67%,是对照的1.18、1.05倍。相对幼苗高度和根耐性指数分别为194.43%、173.72%和125.62%、104.90%;稀释107倍的发酵液用于处理白菜种子,各促生指标达到最高,其中发芽率为92.00%,是对照的1.01倍。相对幼苗高度和根耐性指数分别为140.50%和144.45%。综合分析,草酸青霉菌HB1发酵液较低浓度稀释液有助于提高种子的发芽率,促进蔬菜幼苗的生长;在草酸青霉菌HB1发酵液稀释106倍处理下,黄瓜和辣椒种子生长最好;在发酵液稀释107倍处理下,白菜种子生长最好。
- Abstract:
- Fermentation solution of Penicillium oxalicum was used as research object,via germination test,the influence of Penicillium oxalicum HB1 on the germination rate,seedling growth and root tolerance index of cucumber (Cucumeris),pepper (Purus) and cabbage (Seres brassica) seeds was studied to provide reference for the high quality vegetable seedling.The results showed that the fermentation solution of Penicillium oxalicum HB1 diluted for 106 times enhanced the germination of cucumber and pepper seeds and seedlings growth.The germination rates reached 100.00% and 98.67%,which were 1.18 times and 1.05 times higher than that of the control.The relative seedling height and root tolerance index for cucumber and pepper were 194.43%,173.72% and 125.62%,104.90%.For the cabbage seeds,the suitable level of fermentation liquid of Penicillium oxalicum HB1 was diluted to 107 times.The germination rate was 92.00% and 1.01 times higher than that of the control.The relative seedling height and root tolerance index were 140.50% and 144.45%.These indicated that low level of Penicillium oxalicum HB1 fermentation solution diluents was helpful to improve the seed germination rate,promote the growth of vegetable seedlings.The promotion of fermentation liquid for Penicillium oxalicum HB1 diluted to 106 times on cucumber and pepper seeds germination and seedlings growth was the most significant,and fermentation liquid diluted for 107 times for cabbage seeds.
