Seed Dormancy and Regulation of Germination

Abstract Seed germination and dormancy are vital components of seed quality; hence, understanding these processes is essential for a sound production system. The two closely interrelated regulated, both by genetic as well environmental factors. While provides an inherent mechanism aimed at the survival plant species to withstand adverse external conditions restricting mature from germinating, ability dehydrated remain viable produce vigorous seedling upon hydration under favourable key perpetuation species. In addition, quality expected result in timely uniform field after sowing establish healthy crop stand. Therefore, technology, not considered desirable trait lots used sowing. Thus, achieve highest percentage, factors controlling interlinked contrasting vital. testing trade, knowledge needed reliable assessment its planting value, make right decisions. Though much yet be understood, present status on aspects has made significant advances, especially control, molecular mechanism, physiological influencing dormancy. information compiled this chapter may help technologists developing new methods breaking germination,
