Endophytic Bacillus subtilis Strain E1R-J Is a Promising Biocontrol Agent for Wheat Powdery Mildew

Table 4

The effect of fermentation liquid of strain E1R-j on conidial germination and appressorial formation of Blumeria graminis f. sp. tritici (Bgt).

Treatments	Conidial germination^a			Appressorial formation^b
	Number of observed conidia	Number of germinated conidia	Percentage of germination (%)	Number of observed conidia	Number of appressoria	Percentage of formation (%)
Water control	150	141	93.3	150	129	86.0
Fermentation liquid without bacterial cell^c	150	75	50.0	150	65	43.3

The conidia germination was recorded 8 h after Bgt inoculation.
^bThe appressorial formation was recorded 24 h after Bgt inoculation.
^cThe fermentation liquid was sprayed on to the wheat leaves 24 h before inoculation Bgt.
