Dormancy Breaking and Germination of Rice Seed: Rice - the World 2nd Most Feeding Consumable Cereal

The importance of rice for our country is manifold as it is an agricultural commodity that adds 20% FEC to the national foreign exchange reserves. Seed is a living tissue carries a genetic potential. Failing of seeds to germinate under environmental conditions optimal for germination is called dormancy. True dormancy caused by the conditions within the seed that prevent germination. Thus dormancy is a state of seed, not of the environment, that reduces seed germination and breaking dormancy ,could be one of the most important factor for early germination. Whereas the wild species of rice offer an important source of variability for improvement of cultivated rice. Keeping in view of its importance the present work has been attempted to break dormancy of both the wild species and cultivated rice with different treatments. The outcome of breaking dormancy was the early germination, to increase survival percentage,shorten the nursery period and reduced maturity days. This book describe all the possible dormancy breaking methods of wild species and cultivated varities of rice. This may be helpful & used as protocol in future research studies by researchers.
