However, the area is less studied than other areas of endophyteresearch world wide. Therefore, a series of experiments were carried out in laboratory,glasshouse and field to compare the responses of endophyte infected plants andendophyte free plants of perennial ryegrass varieties to 10 fungal pathogensisolated from turf type ryegrass in Lanzhou. The pathogens used in the experimentswere Alternaria alternata、Bipolaris sorokiniana、Fusarium avenaceum、Curvularialunata、Ascochyta leptospora、Fusarium acuminatum、Fusarium chlamydosporum、Fusarium oxysporum、Fusarium solani and Gliocladium roseum. In addition, someprotective enzymes activity and alkaloids contents of E+ and E- plants were measuredand LpsA gene of the common strain - Lp19 and mutant strain -AR1 of Neotyphodiumlolii were sequenced to identify their ...

The results of mycelium growth rate showed that the value of EC50 against Bipolaria maydis, Macrophoma kawatsukai, Fusanrium oxysporum, Fusarium solaid and Fusarium oxysporium were 0.979, 0.505, 1.733, 0.425 and 0.849mL/L. The result of spore germination proved that the value of EC50 against Alternaria longipes, Exserohilum trucicum, Fulua fulua and Fusarium solani were 1.709, 0.375, 0.445 and 1.333mL/L.

该菌株发酵液对玉米小斑病菌、苹果轮纹病菌、棉花枯萎病菌、马铃薯干腐病菌和西瓜枯萎病菌菌丝的生长抑制中浓度(EC50)分别为0.979,0.505,1.733,0.425和0.849mL/L,对玉米大斑病菌、番茄叶霉病菌、马铃薯干腐病菌和烟草赤星病菌的孢子萌发抑制中浓度(EC50)分别为1.709,0.375,0.445和1.333mL/L。

In this paper, 1554 strains of bacteria were isolated from the soybean rhizophere in the different continuous systems. Those biocontrol bacteria were screened in vitro and in vivo. 6 strains of them had the better control efficacy. They exhibited the different antagonism to the pathogens of soybean root in vitro. The strains 18BR2-2 and 18BR9-1 showed a wide range of antagonism against Fusarium oxysporum, F. avenaoeum, F. solani and Rhizoctonia solani in vitro. The 6 strains exhibited different control efficacy to soybean root rot in greenhouse and in field. In greenhouse, they could decrease the degree of soybean disease significantly, and the control efficacy of 18BR2-2 was the best and can reach 45.90%. In theory, soybean treated by 18BR2-2 may postpone the days of outbreaking of disease for 6 days. The strain 18BR2-2 also promoted the growth of soybean seedling and, raising the soybean height for 11.24%, increasing dry weight for 40.91% and fresh weight for 35.27%.
