Figure 3.
Effect of treatments with mixtures of biological control agents and organic additives (Mix (T. virens + B. velezensis), MixRh (T. virens + B. velezensis + burnt rice husk) and MixChi (T. virens + B. velezensis + chitosan) on (A) stomatal conductance (gs) and (B) leaf water potential (Ψwf) of cape gooseberry seedlings without (light grey bars) and with (dark grey bars) F. oxysporum f. sp. physali (Foph) inoculation at 50 days after inoculation (DAI). Error bars represent the mean of four values ± standard error. Significant differences between treatments are indicated by different letters according to the Tukey’s test (p ≤ 0.05). *** p < 0.001—values of the ANOVA of Foph inoculation, mixture treatments, and their interaction.
