Abstract
Tissue cultures were established from stem explants of Calotropis procera, a hydrocarbon yielding desert shrub on Murashige and Skoog's medium supplemented with 1.5 mg. 1−01 2,4-D + 0.5 mg.1−1 kinetin and polyvinylpyrrolidone. Laticifer cells were not present in young callus but were observed after 4 weeks of callus growth when examined histochemically. These young laticifers were detected in the 5th week of culture and were distinguished from surrounding cells by the presence of characteristic cytoplasm and thin walls. A group of cells with extensive branching was developed after 8 weeks of growth of the callus cultures. These cells were thick walled and contained latex particles in coagulated masses. Positive Liebermann-Burchard test proved the presence of terpenoids in these laticifers.
