Effects of Bacillus megaterium inoculation on hormones. Concentration of shoot ABA (A) and ACC (B) and production rate of ethylene (C) in wild-type cv Ailsa Craig (WT) and flacca (F) mutant tomato plants were determined. Treatments are designed as non-inoculated controls (NI, open bars) or inoculated plants (I, black bars). Data are means ± SE (n = 6). Means followed by different letters are significantly different (P < 0.05) according to LSD’s HSD test. P values for two-way ANOVA are reported in Table 2.
