Alterations in sugar metabolism of Glycine max with cobalt applications

Abstract

Exogenous Cobalt was given to Soybean (Glycine max) plants in pot culture by soil drenching method in order to study the effects of Co stress in the sugar metabolism. For estimating the changes in the sugar metabolism, reducing and non-reducing sugars, total sugar, and starch contents were extracted and estimated from both control and treated plant parts (from roots and shoot). The results showed the low concentrations of cobalt (50 mg kg^-1 Co level) in the soil enhanced these parameters while higher concentration (Co level (100-200 mg kg^-1) in the soil) didn’t show any significant effect.
