Chemical stress induced changes in carbohydrate content and the enzymes of carbohydrate metabolism in germinating maize seedlings


Shobha N, G Savitha

In the present work, the effect of different concentrations of Metalaxyl, a systemic fungicide, on the carbohydrate content and thernenzymes of carbohydrate metabolism during early germination (0-7 days) of maize seedlings is studied. In our study α–amylasernactivity increased progressively in control seeds till 7th day of germination. Maximum activity of α–Amylase with nearly 100 foldrnincrease was observed with 4.5mg/g treated seeds on 3rd day of germination with a gradual decline. Similar pattern of activity wasrnobserved with β-amylase. A gradual decline in the invertase activity was seen in control seeds till 3rd day and further increase onrnsubsequent days. The seeds treated 4.5mg/g of fungicide showed an enhanced activity of invertase on 3rd day. Maximum activity ofrninvertase was observed in both control and fungicide treated seeds. Similar pattern could also be observed with the totalrncarbohydrates, reducing and non-reducing sugars on different days of germination in control and treated seeds. Further work is inrnprogress to understand the mechanism of the interaction of metalaxyl in carbohydrate metabolism, during germination.
