Write the factors that necessary for seeds to germinate
Answers
Answer:
The factors are:
1.Sunlight
2.Water
Factors Affecting Germination Process of Seeds:
Temperature: Extremely low or cold temperature is not favorable for seed germination. They prefer higher temperatures. The germination rate of seed is directly proportional to the rise in temperature.
Moisture or water: Dry seeds do not germinate. Water is an essential factor to trigger off the process of seed germination.
Soil: During growth, seeds require mineral elements for further growth which is obtained from the soil.
Light: For seed germination light is not essential in the early stages of germination but plays a main role in the later stages of the life cycle of plants.
Viability of the seeds: After the seeds are formed, they remain viable up to certain period which may vary from plant to plant or seed to seed. Many sees die or incapable of supporting growth after a certain period of time.
Dormancy period: Many seeds do not germinate abruptly after they are produced . Certain seeds undergoe a resting time through which they stay dormant and germinate when conditions are favourable. Preence of growth inhibitors like abscisic acid induce dormancy in seeds.
Thinness or thickness of seed coat: Different seeds have varying degrees of thickness to enable the seeds to remain feasible. Seeds with a thin seed coat tend to germinate faster than those with thicker seed coats.
