Factors affecting seed dormancy include the presence of certain plant hormones--notably, abscisic acid, which inhibits germination, and gibberellin, which ends seed dormancy. To break chemical dormancy, you might have to leach the seed or use cold/moist stratification or fire :// Abstract. Two basic kinds of dormancy have been distinguished by Bünning (): ectogenous, influenced by external factors such as light, temperature, water, etc.; and endogenous, conditioned by the internal constitution of the r seeds possess either one or both of these types of rest depends upon two main factors, environmental influences and ://   Seed production. Seeds are produced in several related groups of plants, and their manner of production distinguishes the angiosperms ("enclosed seeds") from the gymnosperms ("naked seeds"). Angiosperm seeds are produced in a hard or fleshy structure called a fruit that encloses the seeds for protection in order to secure healthy growth. Some fruits have layers of both hard and fleshy ://   Seed Dormancy and Plant Production Laboratory germination and tetrazolium tests on dry seed indicated that the percentage of inherent dormancy was 83 to 85% of the viable seed used in this study (Table 1).
