Seed germination requires a suitable temperature, a moderate amount of moisture, and sufficient air. First, water is required to swell and soften the seed coat when the seed is germinated. Followed by the air, the seeds need to constantly breathe during the germination process, and the energy can be obtained to ensure the normal operation of life activities. Finally, the decomposition of nutrients in the seed and a range of other physiological activities need to be carried out at a suitable temperature.
Seed Developmental Stage
Swell
When the seeds are immersed in water or fall into moist soil, the hydrophilic substances in the seeds begin to attract water molecules, causing the seed volume to increase rapidly. After the seeds are inflated, the seed coat becomes soft or ruptured, and the seed coat begins to increase in gas permeability, and germination begins. The hydration and enzymes begin to activate, and the respiratory and metabolic effects increase dramatically. The cells divide and enlarge so that the embryos begin to grow, and the nutrients stored in the seeds are also consumed in large quantities. The embryo then breaks through the seed coat and is exposed. The seed first emerges from the radicle and then grows out of the germ. Finally, roots, stems, and leaves are grown and seedlings are formed.
The Germination Rate of Seeds
A successful seed germination factor includes the seed itself and its external conditions, sufficient moisture, suitable temperature, adequate oxygen, and sufficient sunlight.
Vitality Intact Embryo
For the conditions of healthy seeds themselves, they must have a living embryo intact. In short, after leaving the mother, it will gradually lose vitality and cannot germinate for more than a certain period of time. Different seeds have different life spans. For example, seeds of wheat and rice are generally active for three years, while seeds of cabbage and broad beans can live for five to six years. Normal seeds will have sufficient nutrient reserves to supply the materials needed for seed germination. In contrast, dried seeds are often unable to sprout successfully due to a lack of adequate nutrition.
Dormancy
After the seeds are formed, they cannot germinate even when the conditions are suitable. This is mainly due to the state of dormancy. Generally, you need to promote seed germination by releasing dormancy. For dormant seeds, dormancy should be relieved for different reasons to promote seed germination.
