摘要
[目的]研究不同类型芽孢杆菌对辣椒的促生作用.[方法]将辣椒种子分别浸泡于3种芽孢杆菌菌悬液中,记录种子发芽率及根、芽长度,研究各菌株对辣椒种子萌发的影响;采用浸种和灌根2种方式,测定幼苗株高、根长、鲜重指标,研究各菌株对辣椒幼苗的促生作用.[结果]3种芽孢杆菌均能促进辣椒种子萌发及幼苗生长.种子萌发试验中,稀释10倍的GS09菌株菌悬液效果最为显著,相比对照,种子发芽率、发芽势、根长、芽长分别增加了22.74%、15.39%、31.54%、23.33%;幼苗生长试验中,灌根方式优于浸种方式,GS09菌株100倍稀释液下株高、根长、鲜重相比对照分别增加了68.07%、55.56%、65.63%.GS10的促生效果仅次于GS09,GS01促生效果较弱.[结论]该研究可为挖掘新型根际促生菌株以及辣椒的绿色生产提供理论依据.
Abstract
[Objective] To explore the effect of different types of Bacillus strains on the growth-promoting of pepper.[Method] After soaking seeds with three kinds of Bacillus strains,the effect of various strains on pepper seed germination was studied by recording the seed germination rate,root and bud length.Seed soaking and watering root were used to study the growth-promoting effect of pepper seedlings,the plant height,root length and plant weight were determined.[Result] The results showed that three kinds of Bacillus strains can promote seed germination and seedling growth of pepper.In the seed germination test,the growth-promoting effect of GS09 with the bacteria liquid diluted ten times was the most significant.Compared with the control,seed germination rate,germination potential,root and bud length under the treatment increased by 22.74%,15.39%,31.54% and 23.33% respectively.The way of watering root was better than seed soaking in the pepper seedlings test,the plant height,root length and fresh weight of seedling increased by 68.07%,55.56% and 65.63% respectively.The growth-promoting effect of GS10 was the second,and the effect of GS01 was the most weak.[Conclusion] This study can provide theoretical basis for excavating new type of plant growthpromoting rhizobacteria and green production of pepper.
