.4.2. Promotion of the common bean seeds germination by T.
atroviridae
Results from the experiments showed significant effect of T.
atroviridae on bean seeds germination. Significant differences
(p < 0.05) were also noted between treatments, and the optimal
concentration of T. atroviridae conidia suspension that induced fast
promotion and 100% germination from day one to day four of the
study was 2 105 cells/mL. At this cells load, the germination promotion by T. atroviridae was 100% on day one, 50% on day two, and
25% on days 3 and 4. Beyond the optimal T. atroviridae conidia concentration, the tested concentrations (4 105 conidia/mL and
8 105 conidia/mL) showed inhibitory effects relative to the control, with respective percent seed germination of 50% and 25%
throughout the observation period. At tested concentrations, T.
atroviridae could promote the germination of bean seed in day
one of the experiment compared to the control without BCA
(Fig. 7).
