摘要: 目的 分析新疆阿魏内生真菌AW57菌液对小麦种子萌发及幼苗生长的影响,研究有实用价值的内生菌株。方法 以内生真菌AW57和新春31号小麦种子为材料,采用不同浓度的菌液浸种和浇灌处理方式,测定分析小麦种子的发芽率、发芽势以及幼苗的根长、根数、苗高、苗鲜重和苗干重等相关指标。结果 浸种和喷施不同浓度AW57菌液均对小麦生长发育有促进作用,喷施20%浓度菌液小麦促生效果最佳,发芽率高达89.67%,苗鲜、干重分别比对照提高了54.41%、45.45%,对株高、叶长、叶宽和茎粗作用显著,对根数影响不显著,但对根长显著。结论 适宜浓度AW57菌液有利于小麦生长,可作为小麦生长调节剂。

Abstract: Objective The effects of endophytic fungus AW57 from Xinjiang Ferula sinkiangensis K.M.Shen on the germination and seedling growth of wheat were studied, and endophytic strains with practical value were explored.Method The endophytic fungi AW57 and Xinchun No.31 wheat seeds were used as testing materials. The germination rate and germination potential of wheat seeds and the root length, root number, seedling height and seedling fresh weight were treated with different concentrations of bacterial liquid soaking and watering treatment. The relevant indicators such as fresh weight and dry weight of the seedlings were measured and analyzed. Result Soaking seeds and spraying different concentrations of AW57 liquid all promoted the growth and development of wheat. The effect of spraying 20% concentration of bacteria liquid on wheat grow was the best effect, the germination rate was as high as 89.67%, and the seedling fresh and dry weight were 54.41% and 45.45% higher than those of the control, respectively. 54.41% and 45.45% had significant effects on plant height, leaf length, leaf width and stem diameter, but had no significant effect on root number, but significant on root length. The effect of spraying 20% concentration of bacteria solution on wheat growth was the best, the germination rate was as high as 89.67%, the seedling fresh and dry weight were 54.41% and 45.45% higher than those of the control, respectively. The effects on plant height, leaf length, leaf width and stem diameter were significant, but the effect on root number was not significant, but on root length was significant.Conclusion The suitable concentration of AW57 is beneficial to wheat growth and can be used as a wheat growth regulator.
