Germination | Description, Process, Diagram, Stages, Types, & Facts
网页2024年9月10日 · Germination, the sprouting of a seed, spore, or other reproductive body, usually after a period of dormancy. The absorption of water, the passage of time, chilling, warming, oxygen availability, and light exposure may all operate in initiating the process.
Seed Germination: Definition, Steps, & Factors Affecting Them
网页2023年2月2日 · Stage 1: Imbibition: This is the first step where the seed rapidly absorbs water from the environment causing the seed coat to swell and become soft. Stage 2: Activation: The absorbed water activates the enzymes present inside the seed that starts the growth phase in the embryo.
Process of Seed Germination: 5 Steps (With Diagram) - Biology …
网页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 – The Science of Plants
网页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.
Germination - Wikipedia
网页The stages of germination of a pea plant: A. seed coat, B. radicle, C. primary root, D. secondary root, E. cotyledon, F. plumule, G. leaf, H. tap root. The part of the plant that first emerges from the seed is the embryonic root, termed the radicle or primary root. It allows the seedling to become anchored in the ground and start absorbing water.

The Germination Process: How A Seed Germinates And Grows
网页2023年11月24日 · Explore the fascinating process of seed germination, from activation to growth initiation. Discover the factors affecting germination, stages involved, and the requirements for successful germination. Learn about the adaptations in different plants, breaking seed dormancy, and techniques used by gardeners.
4.6.4: Germination - Biology LibreTexts
网页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.
16.4B: Germination of Seeds - Biology LibreTexts
网页2020年12月31日 · The seeds of many temperate-climate angiosperms will germinate only after a prolonged period of cold. An inhibitor within the seed (probably abscisic acid - ABA) is gradually broken down at low temperatures until finally there is not enough to prevent germination when other conditions become favorable.
