Breaking seed dormancy in flower crops: a review

The seed dormancy in flower crops impacts both seed production and their germination. Flower crops display diverse mechanisms for seed dormancy like hard seed coat, immature, rudimentary embryo and inhibitors. In some seeds which are dormant at harvesting, dormancy breaks down naturally over the time whereas other crops require some form of pre-treatment. There are several methods used for specific genera. It can be broken by soil melting and freezing, microorganism's activity, forest fires, soil activity and being eaten by animals, in normal conditions. This review surveys and categorizes of different seed dormancy conditions found in flowering plants. Flower crops are listed according to their dormancy types. There are two types of dormancy, primary and secondar. Specific examples are given for each type of dormancy along with their methods to alleviate dormancy
