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 Seed Germination Process :

What is germination of a seed?

The beginning of the growth of a seed into a seedling is known as germination. All seeds need water, oxygen and the right temperature to germinate. Dormancy is a state of suspended animation in which seeds delay germination until conditions are right for survival and growth.

What are the 3 stages of germination?

In general, germination process can be distinguished into three phases: phase I, rapid water imbibition by seed; phase II, reactivation of metabolism; and phase III, radicle protrusion [6].

How does seed germination work?

In the process of seed germination, water is absorbed by the embryo, which results in the rehydration and expansion of the cells. Shortly after the beginning of water uptake, or imbibition, the rate of respiration increases, and various metabolic processes, suspended or much reduced during dormancy, resume.

Which seeds require light to germinate?

Seeds That Need Light to Germinate

How a seed turns into a plant?

When seeds are planted, they first grow roots. ... As the plant grows and begins to make its own food from nutrients it takes from the soil, it will grow into a larger plant. The seed itself is like a survival package. It contains the food the seed needs while it is growing roots and forming into a small plant.

Do seeds need sunlight to germinate?

All seedlings require sunlight. Seedlings will become leggy and fragile and will not produce to their potential if they do not have sufficient light. Table 1. Soil temperature conditions for vegetable crop germination.

Does grass seed need sunlight to germinate?

Don't bury the seeds any deeper; grass seed needs adequate light to germinate quickly. After raking, pass over the area with a roller, which helps ensure the good seed-to-soil contact your new seed needs.

It absorbes water and starts to grow. First, it produces a small root and then a stem with 2 tiny leaves, called the sprout. That's it. When you can see the sprout, you know the seed has germinated.

Why do seeds not germinate?

The primary reasons for failed germination are: Seeds get eaten – mice, voles, birds, and wireworms all eat seeds. Check to see that the seed is still in the soil. Seeds rot – planted too deeply, over-watered, or in cold weather, our untreated seeds may simply rot.

How many hours of light do seeds need to germinate?

Seedlings need more light than full grown plants, ideally as much as 16-18 hours a day. Additional light may be required for seeds started during the winter months.

Should seeds be covered to germinate?

To speed germination, cover the pots with plastic wrap or a plastic dome that fits over the seed-starting tray. This helps keep the seeds moist before they germinate. When you see the first signs of green, remove the cover.

How germinate seeds fast?

One easy way to make seeds germinate faster is to presoak them for 24 hours in a shallow container filled with hot tap water. Water will penetrate the seed coat and cause the embryos inside to plump up. Don't soak them for longer than 24 hours because they could rot. Plant the seeds immediately in moist soil.

Will a damaged seed grow?

Broken seeds can be added to the compost bin or planted around growing vegetables and flowers. They won't sprout, but they will add nutrients to the soil as they decay.

Does a seed reproduce?

Plants that reproduce by seeds. Seed plants have special structures on them where male and female cells join together through a process called fertilisation. ... The parent plant disperses or releases the seed. If the seed lands where the conditions are right, the embryo germinates and grows into a new plant.
