Fig. 8From: Biological characteristics of two pathogens causing brown blotch in Agaricus Bisporus and the toxin identification of Cedecea neteriEffects of phenylacetic acid and p-hydroxybenzoic acid on color parameters of A. bisporus. a, d Changes in red/green color parameters (a). b, e Changes in yellow/blue color parameters (b). c, f Color parameter lightness (L). The L, a, and b values were measured at the toxin-inoculated sites on the A. bisporus using a Color Reader. Representative data from three biological replicates are shown as mean ± SD (n = 30)Back to article page
