Exogenous 50 μM IAA, 150 μM GA1, respectively, were applied to the excised stumps for 48 h. Control decapitated plants were treated with distilled water. The UI was harvested 48 h after the first application. The data show means ±SE, n=3 for GA1 level, and n=20 for UI elongation rate. FW, fresh weight.
