FIGURE 2.
Effects of fennel roots on zoospore behavior of P. capsici. (A,B) Dynamic process of P. capsica zoospore attraction by fennel roots. (C) Cystospore germination. (D) Chemotaxis ratios (CR): fennel root showed significant attraction to zoospores. (E) Germination rate and motility rate in fennel root and zoospore interactions. CK was a capillary tube replacing the root as the control. Significant differences were based on Chi square test (p < 0.05). The error bars indicate the standard error of the means (n = 3). *Indicates significant differences between the control and plant root treatment at the 0.05 level.
