Induction and differentiation of callus from embryos of Cocos nucifera L. by IAA-conjugates.

Calli from young embryos of Cocos nucifera L. were induced on B5 medium supplemented with IAA-conjugates (IAA-asp or IAA-ala) at a concentration of 2.0 mg/1 and callusing was increased by about 10% if both IAA-conjugates, IAA-asp and IAA-ala were added together. Differentiation of shoots and roots was achieved by transferring calli to B5 medium supplemented with either IAA-asp (2.0 mg/1)+Kn(2.0 mg/1) or NAA (2.0 mg/1). Complete plantlets were obtained on B5 medium supplemented with NAA (0.5 mg/1)+BAP (2.0 mg/1)+PVP (1.0 g/1).
