摘要: Lower concentrations of CuSO4 (25–75 μM) in the MS medium supplemented with 0.1 mg l−1 IAA+5.0 mg Kn+500 mg CH+10 mg Cyst hyd enhanced growth regenerants Dioscorea bulbifera L. (75 μM) induced an appreciable diosgenin yield compared to those obtained on media without Cu. The presence Cu thus seems stimulate production. also differentiated bulbils lower At (100 μM), however, cultures showed poor as well a low yield. Increased proline and protein contents were recorded grown Cu-enriched media.
