Abstract:
Arsenic (As) contamination is a major environmental issue that leads to serious health risks for living organisms. Growth, development, metabolic system, and yield of crops are drastically diminished by exposure to arsenic. Rice is the major dietary source of food for almost 3 billion people of the world. Various strategies to determine the feasible way to reduce uptake and accumulation of arsenic in paddy plants are being studied. The objective of the study was to evaluate the changes in biochemical parameters of rice genotype HUR-105 in response to the different arsenic concentration in the growing solution. Therefore, the effects of arsenic (0, 20, 50, 100, 150, 200 μM) on total chlorophyll content, total soluble sugar content, starch content and total soluble protein content with their percentage reduction in comparison with control were determined. A noticeable decrease in chlorophyll and carbohydrate content as well as protein content was observed with arsenic treatments. From the results obtained in the present study, it can be concluded that rice genotype HUR-105 is sensitive to arsenic stress.
