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.

Jul 20, 2018 · 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.
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.

Nov 17, 2023 · 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 kick off germination: air, water, and warmth.
Feb 11, 2018 · Germination refers to the process by which an organism grows from a seed or a spore. The most common forms of germination include a seed sprouting to form a seedling and the formation of a sporeling from a spore. Thus, germination occurs primarily in plant and fungal species.
Seed germination is a complex process involving a series of physiological changes mediated by environmental cues. From the moment of dispersal, seeds rely on water availability, temperature, and, in some cases, light, to initiate germination or simply break dormancy (Bewley et al., 2013 ).
Jun 7, 2024 · Essentially, a seed consists of a miniature undeveloped plant (the embryo), which, alone or in the company of stored food for its early development after germination, is surrounded by a protective coat (the testa).
Jun 7, 2024 · In some plants, the seeds are able to germinate as soon as they have matured on the plant, as demonstrated by papaya and by wheat, peas, and beans in a very rainy season. Certain mangrove species normally form foot-long embryos on the trees; these later drop down into the mud or sea water. Such cases, however, are exceptional.
