Seed Dormancy

Seed dormancy influences germination patterns in natural ecosystems and impacts persistence of seeds in cultivated fields. It also can alter cultural practices for crop plants by delaying germination or its completion. Studies in this area have provided evidence elucidating dormancy mechanisms in both wild and cultivated plants. Research in this area involves ecological, biochemical and molecular approaches to describe seed dormancy.
