Fig. 1From: Indole-3-acetic acid improves drought tolerance of white clover via activating auxin, abscisic acid and jasmonic acid related genes and inhibiting senescence genesMorphological appearance (a), Stem dry weight (b), relative water content (c) and total chlorophyll content (d) of white clover in different sets. Vertical columns represent Mean + STD (n = 4). The same letter indicates no significant difference and the different letters indicate a significant difference (Fisher’s LSD, P < 0.05) in a pairwise comparison between sets at the same timeBack to article page
