Plantlets from mesophyll protoplasts of Solanum xanthocarpum

Abstract

Young leaves of Solanum xanthocarpum from axenic shoot cultures released viable protoplasts when treated with appropriate enzymes. The protoplasts on culture in modified Murashige and Skoog (1962) medium supplemented with 2,4-dichlorophenoxy-acetic acid (0.5 mg/l), naphtha leneacetic acid (1 mg/l), kinetin (1 mg/l) and organic nutrients of KM (Kao and Michayluk 1975) regenerated to form callus tissue as a result of repeated divisions. Protoplast-derived calli differentiated into shoots on MS medium enriched with kinetin (0.5 mg/l) and rooting could be initiated by transferring the shoot-buds to basal medium.
