Question

How does temperature affect seed germination?

Answer 1

Germination:

1. The beginning of growth of the seed into a new plant is called germination.
2. The embryo formed is later differentiated into plumule (shoot part), radicle (root part) and cotyledons.
3. Germination of a seed depends on a variety of factors such as water availability, oxygen, temperature etc.
4. Optimum temperature is required for the germination of seed.
5. Low temperature retards the embryonic activities whereas high temperature destroys the delicate embryo tissues.
