Physiological and Biochemical Changes to Low Doses of Cadmium in Two Varieties of Oryza sativa L. of Odisha, India

Pallavi Jali, Anath Bandhu Das, Chinmay Pradhan

Cadmium (Cd) is considered to be a non-essential heavy metal which have a significant impact on plants. Effect of cadmium on physiological as well as biochemical activities of two rice plants (var. Udaygiri and var. Jagabandhu) were studied. The germination percentage of var. Udaygiri was 88.89 % at concentration 20 M, 26.67 % in 400 M and that of var. Jagabandhu was 85.55 % in 20 M, 21.11 % in 400 M after four days of Cd treatment. The total chlorophyll content of var. Udaygiri and var. Jagabandhu at 400 M was 248.44g/g, 167.75g/g respectively. Carotenoid content of var. Udaygiri and var. Jagabandhu at 400 M was 98.93g/g, 103.89 g/g respectively. Starch content for both var. Udaygiri and var. Jagabandhu was found to be 14.84g/g, 9.68g/g respectively at 400 M. The total sugar content at 400 M was 3.01 g/g and 2.26 g/g for var. Udaygiri and var. Jagabandhu respectively. The proline content increased upon exposure to 20 M to 400 M cadmium. The above result revealed that increased Cd concentration in the medium showed decreased germination rate, photosynthetic activity, total sugar, starch, but there was an increase in the proline content at different time intervals (7-21 days).
