What is Seed Germination?

Seed germination may be defined as the fundamental process by which different plant species grow from a single seed into a plant. This process influences both crop yield and quality.

A common example of seed germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm.

The Process of Seed Germination

The complete process of seed germination is carried out in the following steps:During the beginning stage of the germination, the seeds take up water rapidly and this results in swelling and softening of the seed coat at an optimum temperature. By rupturing of the seed coats help to emerge the radicle and the plumule to form a primary root. This stage is referred to as an Imbibition.

After the emerging of the radicle and the plumule, the seed activates its internal physiology and starts to respire and produce proteins and metabolize the stored of food. This is a lag phase of the seed germination.

This is a final stage of seed germination. In this stage, the cell of the seeds are elongated and divided, which brings out the root and radicle out of the seed and cotyledons are expanded which, are the true leaves of the new plant.
