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.
Dormancy in a seed refers to a period where the seed is alive but not actively growing. This is a survival mechanism that helps seeds remain viable until conditions are favorable for germination. Factors like temperature, light, and moisture can influence seed 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.
What ends dormancy of a seed?
A combination of factors can trigger the end of seed dormancy, such as exposure to water, light, or certain temperatures. Additionally, hormones within the seed can change, signaling the end of dormancy and the beginning of germination.
What does it mean when a plant or seed is dormant?
When a plant or seed is dormant, it is in a state of suspended growth or activity. This can happen during certain seasons or due to lack of favorable conditions. Dormancy allows the plant or seed to conserve energy until conditions are suitable for growth.
What does germiration mean?
Germination is the process by which a seed sprouts and begins to grow into a new plant. It usually involves the seed absorbing water, breaking its dormancy, and initiating growth of the embryo inside. Germination typically includes the emergence of the root, shoot, and leaves of the new plant.
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.
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 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.
Germination happens between which two stages?
Germination occurs between seed dormancy and seedling emergence. During germination, the seed takes in water and begins to grow, leading to the emergence of a seedling.
