Abstract

The present study was conducted to investigate the toxic effects of cadmium and lead salts on protonemal growth and bud formation. For this purpose bryophyte tissue were acclimated to the laboratory conditions by culturing  on Nitsch’s basal medium supplemented with various salts of heavy metals (Cadmium and Lead) in the specific concentration range 10-8 – 10-4 M to assess physiological  stress- response. Rounding of protonemal  cells and formation of  brood  cells like structures were observed and Bud formation was adversely  affected. The present study thus confirmed the morphological changes by mosses can  be used  to detect heavy metal pollution.

Keywords
