Seed germination begins when the first root breaks through the seed wall and ends when the first pair of true leaves begin the process of photosynthesis. We have already learned that seeds contain embryonic roots, stems, and leaves, and enough food to keep the plant growing until it has the … Stage 3: The three stages in-between are when the primary root, which is called the radicle, develops root hairs, the first young shoot rises emerges from the soil and the first pair of true leaves form to begin to manufacture food for the plant. This process influences both crop yield and quality. Seed germination may be defined as the fundamental process by which different plant species grow from a single seed into a plant. In the first stage of germination, seeds begin to absorb water, a process called "imbibation." Stages involved in Germination process: Seed germination means the growth of embryo into seedling and plant. Most of the higher plants produce fruits which also bear the seeds. The seed coating softens as it absorbs water, and the seed then begins to metabolize, as the water triggers release of an enzyme that speeds cellular respiration, where starch is transformed into sugar. Such five changes or steps occurring during seed germination are: (1) Imbibition (2) Respiration (3) Effect of Light on Seed Germination(4) Mobilization of Reserves during Seed Germination and Role of Growth Regulators and (5) Development of Embryo Axis into Seedling. Water makes the outer shell softer, which is very important to the growth; Stage 2: After so much growth and water, the seed will break open due to swelling.

Seed germination can occur after a period of dormancy and is affected by available light, water, air, and many other variables. Stages of Bean Growth. These seeds fall down from the plant and get spread to different places by wind, grazing animals, etc. A common example of seed germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm. Germination Of a Bean Photographs and article By Lily C. Gerhardt [email protected] G ermination is the process in which a seed, spore, or fungi sprouts, or begins growth. Stage 1: The bean is plated beneath the soil and contains a hard outer shell. The process of seed germination includes the following five changes or steps.
