Dormancy is poorly understood in terms of what causes it although it is likely that very many mechanisms exist, most of them probably chemical in nature. Some responsible compounds have been isolated, but in most cases, how they work is not understood. Breaking of dormancy is reasonably well understood in empirical terms. Things that are known to break dormancy include, particular cycles of wet and dry and/or heat and cold, exposure to one period above or below a certain temperature for a certain minimum period, exposure to certain chemicals (such as smoke), abrasion of the seed-coat (perhaps by being eaten but not digested). The list is considerable and particular seeds may require any one or more triggers to germinate.

What is germanination?
Germination is a process in which a seed or spore awakens from dormancy and starts to sprout.
What do you mean by dormancy in a seed?
Seed dormancy is a condition of plant seeds that prevents germination when the seeds are under optimal environmental conditions for germination. Living, non dormant seeds germinate when soil temperatures and moisture conditions are suited for cellular processes and division; dormant seeds do not.
What are the disadvantages of seed dormancy?
Seed hibernation, also called seed dormancy, is the ability of a seed to remain in hibernation when there is a lack of things essential to their development (water, sunlight, nutrients, etc.) or in harsh conditions (extreme cold, extreme heat, hard ground, etc.).
How do you use dormancy in a sentence?
The word "dormancy" is a noun. An example of a sentence containing the word would be: Most insects transition into a state of dormancy during the cold winter.
What process ends with a new and improved plant?
splitting apart bulbs
Another name for growth of a seed or breaking seed dormancy is?
germination
What a young plant that rests during dormancy?
An embryo inside the seed rests during dormancy
Difference between seed dormancy and seed quiescence?
Some seeds cannot germinate under favourable condition is called seed dormancy whereas some seed cannot germinate in unfavourable condition is called seed quiscence.
Period of rest before the seed germinates?
dormancy
What is meant by dormancy of seed?
a time period in which the seed will not germinate and is unreceptive to outside signals
What is the effect of oxalic acid in germination of seed?
Oxalic acid prevents seed growth by putting the seed into a stage of dormancy.....
What is seed domancy?
Seed Dormancy is a problem in which seed is unable to germinate in a specific period of time, under the most suitable environment.
What has the author G M Simpson written?

What is germanination?

When a seed breaks out of dormancy and its environmental conditions are good it begins to do what?
Sprout!Germinate!
What is the ability of a seed to postpone development during harsh environmental conditions is known as?
dormancy
Distinguish between Seed doemancy and Quiescence?
seed dormancy is unability of seed to germinate due to chemical/anatomical features of seed while quiescence is failure of seed to germinate under unfavourable environment.
