Evaluation of the Biocontrol Potential of Endophytic Fungus Fusarium solani CEF559 against Verticillium dahliae in Cotton Plant

Figure 3

Fusarium solani CEF559 protects cotton plants from Verticillium dahliae infection. (a) Cotton plants of cv. Jimian11 were inoculated with F. solani CFE559 4 days before inoculation with V. dahliae strain Vd080 (Vd): photographed 21 dpi with V. dahliae. (b) Wilt index of cotton plants inoculated with V. dahliae Vd080 (Vd), inoculated with F. solani CFE559 liquid culture 4 days before inoculation with V. dahliae (CEF559 + Vd), and with V. dahliae 4 days before inoculation with F. solani CFE559 liquid culture (Vd + CEF559). (c) Wilt index of cotton plants inoculated with F. solani CFE559 solid culture 4 days before inoculation with V. dahliae. Quantified Verticillium dahliae DNA in roots (d) and hypocotyls (e) of cotton plants for three treatments as in (b). Data are means of three replicate experiments in greenhouse assay. Vertical bars represent standard errors of the means. Different letters indicate significant differences based on Tukey’s HSD test (SPSS, v 20.0) at .
