Histological Studies on Cultured Cells of Cassia Senna

Abstract

Very nearly all callus cultures are derived from tissues composed of vacuolated cells. Two maior types of vacuolated cells are involved: those of the vascular ambium which may already be in a state of active division and variety of parenchyrna cells which are quiescent and have to be induced to divide. Rapid division of tissue leads to the callus from which large masses of highly vacuolated cells are formed.
