Seed dormancy: General survey of dormancy types in seeds, and dormancy imposed by external agents
1965Two basic kinds of dormancy have been distinguished by Bunning (1947): ectogenous, influenced by external factors such as light, temperature, water, etc.; and endogenous, conditioned by the internal constitution of the seed. Whether seeds possess either one or both of these types of rest depends upon two main factors, environmental influences and ...

The seeds of some plant species are dormant and will not germinate when they are placed in an environment generally conducive to germination, that is to say, in conditions of appropriate warmth, moisture and aeration. In some of these, the embryo must undergo physiological and in some cases morphological changes before germination occurs. These changes

Grasses are a principal source of food for mankind and play an important role in stabilizing the land surface of much of the globe. Understanding seed dormancy in the Gramineae is therefore of considerable significance to world agriculture and global ecology.

In the life cycle of higher plants, periods of intensive development are interspersed with periods of “dormancy” where all development or the development of certain organs is completely arrested1. One of these phases of arrested development occurs in the embryo after seed maturation. In order to bring about renewal of development the dispersal unit2 of
