Abstract:
To study the effec t o f rare earth Ce( NO3 ) 3 on rap id clona l propagation o fDio scorea zing iberensis. U sing stem s o fD ioscorea z ingiberensis as explants, different concentrations of Ce ( NO3 ) 3 w ere supp lem ented to them edium ( 1 /2MS + 0. 5μ m o l/L IBA) to study the effec t of Ce 3+ on the ca llus induction m edium, adventitious bud in itia l m ed ium and adventitious root m edium. The ca llus induction w as stim ulated by 5.0 mg /L Ce 3+ ; 1. 0m g /L Ce 3+ stimu la ted the bud initial induction; wh ile 1~ 15 mg /L stimu la ted adventitious root. The callus induction adv entitious bud in itia l and rooting w as stim ulated by the low concentra tions of ra re earth e lements, but h igher concentration inhibited them.
