Evaluation of Physiological and Biochemical Parameters of Onion Seed as Influenced by Different Packaging Materials and Storage Conditions

A lab experiment was conducted for 18 months of the period to study the seed physiological and biochemical parameters like moisture content and electrical conductivity respectively. How the different packaging materials and storage conditions influenced the moisture content and electrical conductivity were evaluated. Onion seeds were evaluated at bi-monthly intervals, and the experimental design followed was a factorial completely randomized design (FCRD) with 3 replications and 2 factors, namely storage conditions such as ambient and cold storage and storage containers (cloth bag, high-density polythene bag (HDPE), polythene bag (700 gauge), aluminum laminated bag, vacuum packed bag), the results revealed that the seeds stored in the vacuum packed bag along with combination of cold storage gave good results at the end of 18 months of storage period i.e., seed moisture content (6.95 %) and electrical conductivity (0.732 dSm-1) respectively compared to other treatments. Next to the vacuum-packed bag with cold storage, the best results were seen in the treatment in which Onion seeds were stored in cold storage with the aluminum laminated bag.
