Abstract

The inability of certain seeds to germinate readily even when they are provided with all conditions required for germination is known as seed dormancy. A dormant seed is not a 'failure'. It may be due to conditions associated either with the seeds itself or with existing environmental factors such as temperature and moisture. In general, in groundnut, bunch types are non-dormant while spreading and semi spreading types are having a varied period of dormancy. The seeds show marked dormancy, ranging from 30 to 360 days.
