Analysis of root-extractable strigolactones quantified by a germination bioassay in different in different corm tissues. Germination of P. ramosa seeds induced by extracts from: P, parenchyma; AB, axillary bud; VT2, vascular tissue from axillary buds and R, roots. GR24 (10–9 and 10–10 M) and demineralized water were used as positive and negative controls, respectively. Bars represent the means of two pools from five independent samples (±SE).
