Fig. 6From: Indole-3-acetic acid improves drought tolerance of white clover via activating auxin, abscisic acid and jasmonic acid related genes and inhibiting senescence genesExpression of senescence-associated genes of white clover leaves in different treatments. SAG101 (a) and SAG102 (b). 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
