Seed germination - the process is long. It is important to create favorable conditions for them, and only when they get into them do they begin to sprout, forming a new plant.
For the successful germination of a seed, a number of conditions are necessary, by fulfilling which one can obtain excellent shoots.
Water
It is believed that one of the most important factors affecting the germination of a seed is the ingress of moisture into it through the vas deferens. After the water has penetrated inside, nutrients dissolve in it and thus the embryo takes them to start its growth.
The germination of lotus seeds can persist for 2 thousand years. This is confirmed by the fact that these seeds found in the Egyptian pyramids perfectly sprouted, as if they had been collected recently.
Air
Oxygen is also important. All plants need air to ensure life, because they also breathe, like all living organisms. Therefore, storing seeds in containers that do not allow enough air to pass through is strictly prohibited.
Germination
This is a very important indicator of seed quality. It should be recognized in advance before planting a garden. Only seeds with living embryos are capable of germination, but with dead ones, they lose their germination ability. Its value is the percentage of germinated seeds to the total number of seeds sown. No culture has 100% germination. With long-term storage of seeds, this indicator in most plants decreases.
Nutrient supply
In order to begin to grow and develop, the germ must be nourished. Since he himself is not yet able to synthesize useful substances, they come from the cotyledon or endosperm. And if the supply of organic food is insufficient, then the embryo develops poorly and eventually dies. To prevent this, farmers use starter fertilizers.
Temperature mode
This factor is different for all types of plants. Seeds such as cucumbers or bell peppers can germinate only at high temperatures, above + 15 ° C, they are heat-loving. Carrots, wheat, radishes germinate well already at + 2 ° C, they are cold-resistant plants.
Therefore, the sowing process takes place at different times, something is planted in March – April, and something is only closer to the beginning of summer. The reason for germination at different temperature conditions lies in the origin of the plants themselves. If they occurred in warm regions, they will be thermophilic, while those who leave cold latitudes are cold-resistant.
Lighting
Most seeds grow only in the dark. But there are those that germinate only in the light. Thus, light can also affect germination.
The World Seed Repository is located on Svalbard. Created it in the event of a global catastrophe. This repository was compiled by the whole world. Each country has its own seed bank. The total amount of material in the repository is approximately 4.5 million samples.
Embedment depth
When planting seeds in the soil, the depth at which they are placed must be taken into account. There is such a pattern: large seeds are buried deeper, smaller ones are closer to the surface of the earth.
If you create all the favorable conditions for germination, this will greatly accelerate the emergence of seedlings. An additional bonus will be the reduction in the likelihood of plant damage by various pests and fungi. Therefore, it is very important to take into account the influence of all environmental factors on the germination of seeds, and in the future to get a rich harvest.
