Abstract

Seed plays an important role in agricultural sector for both production and consumption purpose. Availability of vigour seed is one of the major constraints for maximizing crop production. However, healthy seed can also lose its viability during seed storage by changing different physio-chemical properties. Influence of environmental factors and seed containers during storage leading to seed deterioration. In this research, mid storage seed hardening treatment was applied in different aged seeds of jute species (C. Capsularis & C. olitorius) with two types of storage bags. Seed hardening treatment showed the less moisture content with better germination percentage compared to the untreated species of jute seeds. Seed packing in polythene bags during both short and long term seed storages had higher viable seeds compared to the cloth packing seeds. The effect of seed hardening treatment on seed oil content and pattern of oil degradation is distinct in early period of storage. The faster rate of oil degradation, soluble protein and free amino acids was found in seeds of un-treated stored seeds in cloth bag. Contrary, very slow rate of oil degradation was observed in harden seed and stored in polythene bag which indicated better storability of harden seeds.

Highlights

Main purpose of seed storing is to use seed for the cropping season
After one year of storage of different aged jute seed, thousand seed weight ranged from 3.1 gm to 3.5 gm and 1.7 gm to 2.0 gm in C. capsularis and in C. olitorius respectively (Table 1)
Seed weight of untreated seed in cloth bag was little increased in 3 months and 9 months storing compared to the hardened seed in cloth bag for C. capsularis seed (Table 1)

Summary

Introduction

Main purpose of seed storing is to use seed for the cropping season. Mature seeds are considered to have maximum viability but storage causes loss of viability leading to seed death [1]. In storage, seed deterioration is a common process that occurs in all seeds [2]. In the seed deterioration process different physiological and biochemical modification arises in naturally aged seeds. Lipid peroxidation is remarkable which is enhanced in stored seed that negatively affect the seed viability [3]. Lipid peroxidation is associated with the chemical modification of lipid reserves in stored seeds resulting from the production of free fatty acids in oil rich seeds due to high susceptibility to peroxidation [4, 5]
