Seeds of Brassica's and related species (Crucifers), having increased dorman cy coupled with greater tolerance to stresses associated with fall seeding in long winter climates, are produced by treatment with solutions of sugars and/or polyols, generally containing an antifungal/antimicrobial agent, for a specified period, typically 10 to 70h at room temperature, followed by air drying to ambient moisture content Domancy is generally released on overwintering, moi st chilling or hydration-dehydration-rehydration or as a function of increasing temperature or time or a combination of the preceding. Treated seeds afford better emergence over a larger seeding window for fall sown seeds of Brassica's and related species thus increasing the attractiveness of this practice for these crops.
