CYT—cytokinins (zeatin and kinetin), IAA—indole-3-acetic acid, GAs—active gibberellins: GA1, GA3, GA4, GA5, GA6, and GA7, non-active gibberellins: GA8 and GA20, ABA-free—active abscisic acid; ABA-glc—non-active abscisic acid, ABA glucosyl ester; SA—salicylic acid; JA—jasmonic acid; JA-Met—methyl jasmonate. Values represent means (n = 12) ± SE. Different superscript letters (a, b, c, …) within rows for each hormone indicate significant differences between means (Duncan’s multiple range test; p < 0.05).
