Semi-quantitative RT-PCR analysis of the expression of (a) WFSAG12, (b) WFSAG21 (c) WLS73 and (d) WPS46 genes in detached flowers treated with water (control), STS, 6-MP and kinetin. Expression is reported as % of maximum value ± SE (n ≥3), normalised to levels of 18S rRNA expression. For water-treated flowers days after start of treatment (DAT) 1, 2, and 3 correspond to Stage 2, 3 and 4 respectively. For STS/6MP/kinetin treated flowers, DAT 1, 2, and 3 correspond to Stages 2, 3 and 3 respectively. Asterisks indicate significant differences of relative expression compared to water control on each day as determined by a Dunnett’s test (*P < 0.05; ** P < 0.01; *** P < 0.001). Letters indicate significant differences within treatments by one-way ANOVA and a Tukey’s range test (P < 0.05)
