- 摘要:
- 以胶质芽孢杆菌菌剂为研究对象，研究了其对黄瓜、番茄、茄子及辣椒4种蔬菜种子发芽率及幼苗生长的影响。结果表明：该菌剂处理的黄瓜、番茄、茄子和辣椒种子发芽率均高于对照组，依次是对照的1.10、1.10、1.07、1.07倍；处理组幼苗根长分别比对照增加3.76%、32.82%、1.50%和15.70%；处理组幼苗干质量分别比对照增加36.36%、-12.82%、3.13%、16.67%，G值、根冠比与对照无显著差异。综上所述，胶质芽孢杆菌菌剂能够提高4种蔬菜种子的发芽率，但对蔬菜幼苗根生长的影响因蔬菜种类不同而异。
- Abstract:
- The aim of this study was to investigate the influence of Bacillus mucilaginosus agents on the germination rate and seedling growth of cucumber，tomato，eggplant and pepper seeds.The results showed that germination rate of cucumber，tomato，eggplant and pepper seeds with Bacillus mucilaginosus agents were 1.10，1.10，1.07 and 1.07 times of control.The root length of treatment group was increased by 3.76%，32.82%，1.50% and 15.70% respectively.In the treatment group，the dry weight of seedlings was increased by 36.36%,-12.82%，3.13%，16.67%，respectively.G value，the root shoot ratio had no significant difference with CK.In summary，Bacillus mucilaginosus agents could improve germination rate of four kinds of vegetable seeds，however，the effect of root growth of vegetable seedlings varied with different vegetable species.
