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 the inactive stage of a seed known as?
The inactive stage of a seed is known as dormancy. During dormancy, the seed is in a state of suspended animation, waiting for the right conditions to germinate and start growing into a plant.
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.
Scarification technique in breaking dormancy for Mimosa diplotricha?
Scarification is a method to break seed dormancy by making a small cut or abrasion on the seed coat, allowing water to penetrate and kickstart germination. For Mimosa diplotricha seeds, scarification can be done by using sandpaper to gently rub the seed coat, or by soaking the seeds in warm water for a few hours before planting. This process helps mimic natural conditions that would trigger germination in the wild.
What is seed germenation?
Seed germination is the process by which a seed begins to grow into a new plant. It typically involves the seed absorbing water, breaking dormancy, and sprouting a root and shoot. Germination is triggered by environmental conditions such as moisture, temperature, and light.
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.).
Difference between seed dormancy and seed quiescence?
Seed dormancy is a period where a viable seed is prevented from germinating even under optimal conditions, while seed quiescence is a state where a seed is capable of germination but does not because of unfavorable environmental conditions. Dormancy is more of an inherent property of the seed, while quiescence can be induced by external factors.
Another name for growth of a seed or breaking seed dormancy is?
germination
What is physiological dormancy?
Physiological dormancy is a type of seed dormancy where the embryo is underdeveloped and unable to germinate even under suitable conditions. This dormancy is mainly regulated by internal factors within the seed that need to be overcome for germination to occur.
What a young plant that rests during dormancy?
An embryo inside the seed rests during dormancy
What is the inactive stage of a seed known as?
The inactive stage of a seed is known as dormancy. During dormancy, the seed is in a state of suspended animation, waiting for the right conditions to germinate and start growing into a plant.
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 exogenous dormancy?
Exogenous dormancy refers to a period of dormancy induced by external factors such as environmental conditions like temperature or humidity. This type of dormancy is not inherent to the seed itself but is a response to external stimuli.
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 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 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 is the ability of a seed to postpone development during harsh environmental conditions is known as?
The ability of a seed to postpone development during harsh environmental conditions is known as dormancy. This allows the seed to wait until conditions are more favorable for germination and growth.
