Estimation of Biochemical Changes in Green Gram (Vigna radiata L.) during Storage

This study sought to determine the optimal storage conditions for green gram seeds by evaluating biochemical changes under various conditions. Eight green gram genotypes were stored in different containers, subjected to both ambient and refrigerated conditions, and monitored over a twelve-month period. Initially, the seeds were cleaned and sun-dried to achieve a safe moisture content of 8%. Throughout the storage period, assessments were made bi-monthly to measure protein and carbohydrate content, as well as electrical conductivity of the seeds. The results revealed a significant decline in protein and carbohydrate content, accompanied by an increase in electrical conductivity over time. Notably, genotypes G₆ (IPM-512-1), G₅ (Samrat), and G₁ (Pusa Vishal) consistently demonstrated the highest levels of protein and carbohydrates throughout the storage period. Among all storage conditions, seeds kept under refrigerated conditions (T₆) maintained the highest levels of both protein and carbohydrates. Furthermore, G₁ (Pusa Vishal) exhibited the lowest electrical conductivity during storage, with refrigerated conditions (T₆) proving to be the most effective in preserving the lowest electrical conductivity over the twelve-month period.
