aData were listed as mean ± S.E.
bValues followed by different letter (a–d) in the column are significantly different according to a Duncan’s Multiple Range Test at P < 0.05.
cS1, different inoculation treatments.
dD1, different incubation times (5 days).
e***, significantly different according to a two-way ANOVA at the 0.1% level with F value.
