The process of seed germination includes the following five changes or steps:
imbibition, respiration, effect of light on seed germination, mobilization of reserves during seed germination
, and role of growth regulators and development of the embryo axis into a seedling.
What are the main stages of seed germination?
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.
What are the 6 stages of germination?
For humans, the progression is infant, toddler, adolescent, young adult, middle aged adult, and senior citizen, while plants go from seed to sprout, then through
vegetative, budding, flowering and ripening stages
.
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].
What is the germination process?
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.
What are the 5 stages of seed germination?
The process of seed germination includes the following five changes or steps:
imbibition, respiration, effect of light on seed germination, mobilization of reserves during seed germination, and role of growth regulators and development of the embryo axis into a seedling
.
What are the 4 steps of germination?
- Imbibition: water fills the seed.
- The water activates enzymes that begin the plant's growth.
- The seed grows a root to access water underground.
- The seed grows shoots that grow towards the sun.
- The shoots grow leaves and begin photmorphogenesis. Was this answer helpful?
What makes a seed germinate?
All seeds need
water, oxygen, and proper temperature
in order to germinate. … Some germinate better in full light while others require darkness to germinate. When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat. The embryo's cells start to enlarge.
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.
How do you speed up seed germination?
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.
What three things are needed for germination?
- 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 is not needed for germination?
Complete step by step answer: Development of plants from a single seed is called seed germination. Factors such as oxygen, water and temperature are required for seed germination, but
the light
is not an essential factor amongst other factors.
What are the two types of germination?
- Epigeal Germination: In this type of germination, the hypocotyl elongates rapidly and arches upwards pulling the cotyledons which move above the soil. …
- Hypogeal Germination: In this type of germination, the epicotyl elongates and the cotyledons remain below the soil.
What seeds germinate quickly?
The fastest germinating seeds include everything in the cabbage family –
bok choi, broccoli, kale, cauliflower etc, and lettuce
. The slowest seeds to germinate are pepper, eggplant, fennel, celery, which may take 5+ days. The rest such as tomato, beets, chard, squash, onions, will take about 3 days.
Which seed grows fastest?
- Cornflowers. Cornflower seeds are an easy and budget-friendly seed to grow in your garden. …
- Poppies. As with many fast-growing plants, poppies come in many varieties. …
- Marigolds. Marigolds are a fast-growing flower. …
- Sweet Pea. …
- Sunflowers. …
- Petunias. …
- Nigella.
What to do after seeds germinate?
Fill the containers and pack the soil firmly to eliminate gaps. Remember that most mixes contain few, if any, nutrients, so you'll need to feed the seedlings with
liquid fertilizer
a few weeks after they germinate, and continue until you transplant them into the garden.
