Abstract

In order to evaluation of Effect of storage conditions, duration and packaging on viability and vigor of soybean, an experiment was conducted as a factorial experiment (2×3×5) in the field (completely randomized block design and laboratory (completely randomized design) with three replications in agricultural and natural resources research center of Mazandaran, Iran in 2010-11 and 2011-12. This experiment was included 30 treatments (first factor: five types of packaging as a) two layer paper pack, b) three layer paper pack, c) two layer paper pack with laminate layer, d) cloth pack.5 Propylene pack. The second factor had three levels storage period, 2, 4 and 6 months. Third factor: two storage condition.1) ambient condition and 2) controlled storage condition with 16◦C and 65% relative humidity. The results show that by increasing of seed storing period from 2 to 6 months the rate of germination was decreased from 84.87% to 79.25%. The higher rate of germination in the controlled storage condition with three layer paper pack was observed (88.62%) than ambient condition with Propylene pack (63.94%). Based on the results of the accelerated aging test by increment of storage duration from 2 to 6 months the rate of germination was decreased from 81.81% to 76.61%. The highest germination rate was related to three layer paper pack meanwhile the lowest germination rate was related to Propylene pack and cloth pack. The seed quality indices showed good statues in the controlled seed storage condition than ambient condition in both consecutive years. Also it was noticed that the highest and lowest final emergence seedling percentage was related to controlled storage condition with three layer paper pack (81.98% in the first year and 80.89% in the second year) and ambient condition with Propylene pack (62.31% in the first year and 62.08% in the second year). Generally it was noticed that storing the seed in three layer paper pack with controlled storage condition was suitable for preservation of soybean seeds.
