2. Effect of single and dual inoculation of F. solani and T.
atroviridae on the agronomical parameters of Phaseolus vulgaris
The results presented in Table 3 indicate the beneficial impact
of treatment of bean seeds with T. atroviridae compared to the
deleterious effects of infection with F. solani. However, the negative
impact of F. solani on the growth of P. vulgaris (P > 0.05) was corrected
by treatment with T. atroviridae. Fig. 9(A and B) shows that
plants treated with T. atroviridae grew faster with higher vigor
index compared to the other treatments. Of note, F. solaniinfected
plants that were treated with T. atroviridae showed an
average vigor index 1.6-fold higher than that of plants treated with
F. solani only. Moreover, T. atroviridae treatment led to plants withoptimized agronomical parameters (root length, shoot length, root
fresh weight, shoot fresh weight) that were magnified about 1.95
times on average compared to results obtained with F. solani treatment.
This is an indication that BCA treatment boosted plant metabolism
leading to more tissue formation.
