Potato extract (PE), corn extract (CE) and papaya extract (PAE) significantly enhanced plantlet regeneration from PLBs (protocorm-like bodies) when 50 mL L - 1 of an extract was supplemented to the New Phalaenopsis (NP) medium containing sucrose. Among the treatments, CE 50 mL L - 1 induced the highest rate (66.63%) of plantlet regeneration from PLBs. Organic extracts of potato, corn and papaya at 50-100 mL L - 1 in NP medium also enhanced the subsequent growth of mini-plantlets. However, a higher level (200 mL L - 1 ) of extract in the medium inhibited the growth of the plantlets. Among these extracts, PE at 100 mL L - 1 showed the optimum effect on the acceleration of shoot growth while CE at the same concentration was optimum for root growth.
