Effect of seed storing temperature on germination of wild mustard (Sinapis arvensis) seeds

Seed dormancy of wild mustard (Sinapis arvensis) could be changed through seed storing. The seeds were collected from four regions: Fars, West Azarbaijan, Khuzestan and Mazandaran provinces. They were stored at three different temperatures (-18, +3 and 22-25°C) for 3, 6, 9, 12 and 15 months. They were then put under suitable condition for germination. Mean germination time for seeds was measure...
