Germination - Wikipedia
Germination is usually the growth of a plant contained within a seed resulting in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule.
Seed germination - Process, Necessity, and its Major Factors
2018年7月20日 · 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.
4.6.4: Germination - Biology LibreTexts
The first step in germination and starts with the uptake of water, also known as imbibition. After imbibition, enzymes are activated that start to break down starch into sugars consumed by embryo. The first indication that germination has begun is a swelling in the radicle.
Process of Seed Germination: 5 Steps (With Diagram) - Biology …
The process of seed germination includes the following five changes or steps. 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.
2.2: Introduction to Seed Germination - Biology LibreTexts
2022年7月27日 · At germination, the seed’s metabolic pathways are activated, leading to embryo growth and emergence of a new seedling. Germination begins with activation by water uptake. We call this imbibition, and sometimes the seed or fruit requires special treatment for water to get into the seed and start this process.
Seed Germination: What Do Seeds Need to Sprout?
Germination is the process a seed goes through when it “wakes up” from its dormant state and starts to grow. Seeds are self-contained systems that contain most of what they need to get themselves started, but there are three important triggers that …
What is Germination of Plant? Definition, Process & Factors …
Germination of a plant refers to a phenomenon in which a seed germinates to form a new seeding or plant. The germination process results in the emergence of the radicle (primary root) and plumule (primary shoot). Before germination, the seed remains dormant in the soil.
