Summary
Young leaf segments from plants growing both in vivo and in vitro were cultured on Murashige and Skoog (MS) medium supplemented with auxins [naphthaleneacetic acid (NAA), 2,4-dichlorophenoxyacetic acid (2,4-D)], cytokinins [kinetin (KN) and N6-benzyladenine (BA)] and coconut liquid endosperm (CW). The explants from mature leaves did not show any growth and turned necrotic, while those obtained from juvenile leaves growing in vitro developed protocorm-like bodies (PLBs) at their cut surfaces within 4–8 wk depending on the growth medium. An optimum of 18 PLBs developed from leaf explants on medium supplemented with 2.0 mg l−1 (8.87 μM) BA. Upon subculture in basal MS medium, the PLBs differentiated into plantlets within 6–8 wk. The resulting plantlets were successfully transferred to vermiculite initially and subsequently to potting mixture; 84% of the plantlets survived after 3 mo. of transplantation.
