Abscisic acid (ABA) abundance in the tiller IV and auxin, gibberellin (GA) and cytokinin (CTK) levels in tiller nodes and under control and low R/FR conditions. ABA (A) levels in the tiller IV and indole-3-acetic acid (IAA;) (B), GA (C) and CTK (D) levels in tiller nodes treated for 7, 14 and 21 d. GA levels were the sum of GA1 and GA4. CTK levels were the sum of tZ and tZR. Data are the means of three biological replicates ± SE, and the asterisk denotes a statistically remarkable difference (P < 0.05) between treated and control samples.
