Toxicity impacts of sewage effluent on the amylase activity of pigeon pea (cajanus cajan l.) plant laura, j. s., ajit singh and jyoti rana

Abstract: 

Seed germination represents a crucial phase in the life cycle of angiosperms. Sewage is used for the irrigation of crops in field around most cities. Analysis of the sewage revealed presence of heavy metals which are known to suppress seed germination. Hence in the present investigation, the effect of sewage on the activities of total amylase, α-amylase and β-amylase in Pigeon pea plant has been studied. The activity of the enzymes was found to be significantly affected by higher concentration of sewage effluent due to unacceptable range of heavy metals in sewage effluent. The activity was found to be concentration dependent, activity being least in 100% sewage as compared to 50% sewage application. The study was found that the enzyme activity at each day was lower for the seedling treated with sewage effluent than control, activity and sugar production was found lowest for the highest concentration of sewage i.e. 100%.
