Involvement of ABA in induction of secondary dormancy in barley (Hordeum vulgare L.) seeds

At harvest, barley seeds are dormant because their germination is difficult above 20degC. Incubation of primary dormant seeds at 30degC, a temperature at which they do not germinate, results in a loss of their ability to germinate at 20degC. This phenomenon which corresponds to an induction of a sec...
