Three conditions for seed germination

1. Suitable temperature

When seeds are about to germinate, the decomposition of organic nutrients in the endosperm and cotyledons of the seeds, and the assimilation of organic and inorganic substances into the essence of life, all these activities are carried out under the catalysis of various enzymes. Enzymes will only catalyze at a certain temperature, so temperature is a necessary condition.

2. Sufficient water

Dry seeds contain very little water, generally only 5% to 10% of the total weight of the seeds. Under such conditions, the seeds will be very weak. After the seeds absorb enough water, the seed coat will swell and soften, allowing oxygen to enter, respiration to be enhanced, and seed activity to be strengthened.

3. Sufficient oxygen

When the seeds get the appropriate temperature and sufficient water, they will begin to germinate. When there is sufficient oxygen, the respiration of the embryonic cells will gradually increase and the enzyme activity will be vigorous, providing the needs for seed germination.
