Fig. 9From: Genome-wide identification of SERK genes in apple and analyses of their role in stress responses and growthHeight of Malus hupehensis seedlings after brassinosteroid (BR) and auxin treatments. Plant height was measured at 0, 1, 2, 3 and 4 weeks after BR (a) and auxin (b) treatments. Bars show mean ± standard error (n = 3). Stem diameter was measured at 0, 1, 2, 3 and 4 weeks after BR (c) and auxin (d) treatments. *Significant difference at 0.05 level, **Significant difference at 0.01 levelBack to article page
