Stupid Question: What exacly does "germinate" mean?

Question

I always thought it was when the seed finally turned into a sprout. Is that what it means? For example, "germination usually take 20-30 days". What exacly does that mean?

Answer 1

Seeds are dormant embryos. External factors like oxygen, light, water and temperature are important in triggering the transition from the dormant state to the active sprouting process we call germination. Water entering the seed is the most common trigger, but all external factors needed by a seed must be satisfied for successful germination. These external factors start internal metabolic activities like cell enlargement and cell division. These internal processes can last for varying periods of time such as you have seen in your example (20-30 days to germination). They ultimately result in the seed splitting open and the deployment of the preformed embryonic root structure (radicle) and rudimentary shoot (plumule), including the unfolding of seed leaves (cotyledons). So, the germination period starts from the time the seed ends dormancy (starts growing) and stops when the seed sprouts its embryonic root, stem & leaves. It is the resumption of growth.

Answer 2

For most people and purposes, germination is when a seed sprouts and emerges from the soil. A percent germination, for a batch of seeds, would be determined from the number of seedlings that result after the seeds are sown. The germination time is the number of days it takes a seed to emerge from the soil, or sprout, after sowing, under average temperatures (cold or extremely hot temperatures could slow the germination; optimum temperatures can speed up germination).
A researcher, botanist, or specialist farmer, would define seed germination as a process, beginning with a seed, and ending with a plant. Mother nature has many variations on seed germination, from seeds which sprout while still on the mother plant, to seeds with long germination periods or complex requirements for germination.

Answer 3

Germination means is the period when the seeds begin to sprout. Many factors contribute towards seedling.

Answer 4

Germ..."germ (jûrm) Pronunciation Key
n.
Biology A small mass of protoplasm or cells from which a new organism or one of its parts may develop.
The earliest form of an organism; a seed, bud, or spore.
A microorganism, especially a pathogen.
Something that may serve as the basis of further growth or development: the germ of a project.

as in 'wheat germ'....

(germ)ination... ination..." the process of becoming..."

so germination would be the innermost part of the seed, in the process of becoming a new individual plant....or just plain going from seed to sprout!... *smile*...........

Answer 5

Germination is when the seed sprouts.
