Question: What Are The 3 General Stages Of Seed Germination?

What are the three things seed required for germination?

Temperature, moisture, air, and light conditions must be correct for seeds to germinate..

What are the 5 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 stages of seed germination?

The Seed Germination ProcessStep 1: Imbibition: water fills the seed.Step 2: The water activates enzymes that begin the plant’s growth.Step 3: The seed grows a root to access water underground.Step 4: The seed grows shoots that grow towards the sun.Step 5: The shoots grow leaves and begin photmorphogenesis.

What is the final stage of germination?

The emergence of radicle is considered as the end of stage 1 i.e. activation or awakening stage. 2. Translocation stage: Food materials like fats, carbohydrates or proteins are stored in the endosperm or in the cotyledons.

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 is the first stage of seed germination?

imbibitionThe first stage of germination, called imbibition, occurs when the seed is exposed to water. The seed absorbs water though its seed coat. As this happens, the seed coat softens. Next, water triggers the seed to begin converting starch to sugar.

What makes a seed germinate?

All seeds need water, oxygen, and proper temperature in order to germinate. Some seeds require proper light also. … Then the seed coat breaks open and a root or radicle emerges first, followed by the shoot or plumule that contains the leaves and stem. Many things can cause poor germination.

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].
