Gibberellic acid (GA₃) and cytokinin content (CTK) (ng g⁻¹FW) in the leaves and roots of tomato plants under soil water contents of 75–70% and 55–50% in the different soil textures of China. Treatment values presented for comparison are the means of three replications (± SE, standard error). Means followed by different letters are significantly different (p ≤ 0.05) according to Tukey’s test
