When the seeds are ripe, they can be harvested and stored for sowing next year.
The seeds are put in boxes, linen or paper bags. A label is attached to each bag of seeds with the name of the plant from which they were collected and the time of their collection.
The seeds are stored in warm (20–30 ° C), well-ventilated rooms. These conditions are necessary for the seeds to dry.
Life processes in dry seeds are very slow, but still the seeds breathe and retain some of the moisture. Dry seeds can survive for several years.
Necessary conditions for seed germination
1. Oxygen, as during germination the seeds breathe very intensively.
2. Humidity. But if there is too much water, then the seeds do not have enough oxygen, and the embryos in the seed may die.
3. Appropriate temperature. In early spring, cold-resistant plants are sown, for example, wheat, peas, carrots. Later, when the ground warms up, heat-loving plants are sown, for example, cucumbers, beans, pumpkin.
The seeds are sown in well-prepared soil – loosened, nutrient-rich and moist enough.
Many plants are initially planted in greenhouses and greenhouses and later transplanted into open ground.
Scientists who create new varieties are breeders, they store seeds in a seed bank – a large storage in special vessels on the shelves.
