Abstract
In the present investigation the cytological effects of leaf homogenate of T. indica on Allium cepa root meristem were studied. The lower concentration of leaf homogenate caused mitoactivation while higher ones were mitodepressive. The leaf homogenate induced both physiological (stickiness of chromosomes, lagging chromosomes, hyperploid cells, etc) and clastogenic (chromosome breaks, ring chromosome and chromatin bridges) type of aberrations. Recovery of roots with 24 hr over water after treatment with leaf homogenate was not enough for normalisation of pattern of cell division.
