* seed dormancy is mainly caused by abscisic acid. Dormancy allows seeds to Tolerate desiccation and temperature better. The buds as well as seeds sprout only when abscisic acid is overcome by gibberellins.
* auxins are employed to increase the period of dormancy in tubers, bulbs & corms so that they can be stored for prolonged periods while abscisic acid is considered to be a general inhibitor hormone which promotes dormancy.
