摘要：The seeds of Triticum aestivum var. MP LOK1 were sown in earthen pots and cadmiumchloride treatment was given. The plants were treated with increasing concentrationsof cadmium chloride i.e., 25, 50 and 100 ppm. The aim of this work was to determinethe effects of cadmium chloride on the photosynthetic pigments, polyphenol, prolineand antioxidative response in Triticum aestivum. It is evident from the results thatchlorophyll content of the wheat was not much affected by the lower levels of cadmiumchloride but significantly affected at 100 ppm level. It was slightly increased only at 25ppm by 5.10%. The polyphenol content of the leaves was increased at 25 and 50 ppmof the cadmium chloride but decreased by 16.54% at 100 ppm of the metal salt.Maximum increase in proline content was found as 27.36% at 100 ppm of cadmiumchloride. The increased levels of polyphenols at elevated levels of cadmium chloridemight be to tolerate higher levels of cadmium stress. The elevated activities of catalaseand peroxidase under metal salt probably came for maintenance of cellular membraneswhile decrease at elevated levels of cadmium chloride might be due to the toxic natureof cadmium chloride. The details of the parameters studied are discussed in the presentpaper.
