Much depends on the variety and quality of the seeds, but care for the future harvest should be started already at the stage of seed germination. There are methods of stimulation, after which even hard-growing seeds will sprout.

Warming up and irradiation
In order for the seeds to germinate well, you should not use several stimulation methods at once. It is recommended that you consider all the options and then pick one. If you apply several methods at the same time, then the effect may turn out to be the opposite.
Dry heating of seed to increase the percentage of germination is carried out near a heat source. The beans can be laid out on a baking sheet and placed on a radiator. The temperature should not be high, i.e. not higher than + 40 ° C. Warming up should be carried out within 5-7 days.
The heat stimulation process can be accelerated. To do this, you need to immerse the seeds in water heated to + 50 ° C... + 60 ° C, but not higher. If the temperature is higher, the product may cook. The seeds should sit in the water for about 20 minutes. To keep the liquid cool, you can periodically check the temperature with a thermometer and add hot water if necessary. Another way is to pour hot water over the seeds in a thermos.
Warming up pumpkin seeds not only increases the percentage of germination, but also contributes to the formation of female flowers in the garden culture (in the future).
Irradiation with red light will also help stimulate germination. Under the influence of the lamp, future crops should be 5-15 minutes.
Store drugs
An affordable and effective method of stimulating seed germination is soaking in hydrogen peroxide. In order not to harm the seed, it is recommended to take a 3% solution. Peroxide destroys growth inhibitors that are present in any seed, so the germination rate increases.
In order for the grains to be saturated with oxygen, they must stand in hydrogen peroxide for 15-20 minutes. When the time is up, the grains are washed and sown in the usual way. You can carry out a long soak in 3% hydrogen peroxide, but you will additionally need to reduce the concentration of the antiseptic. To prepare the stimulant, dissolve 1 tsp in 1 glass of water. peroxide. In the resulting liquid, you can keep seeds from several hours to 2 days.
An alternative way to stimulate and oxygenate is to soak in standing water with the aquarium compressor turned on.
Chlorella (an organic natural preparation that stimulates plant growth) will help improve germination and germination. The agent acts gently on the seed. It contains various useful substances, phytohormones, and also performs a protective function. The drug has a depressing effect on pathogenic microflora.
Cultures with a thin seed coat, such as cucumbers, tomatoes, cabbage, etc., should be kept in the organic stimulant for 5-7 hours. When the grains have a thick shell, such as legumes, soak is carried out for 15-20 hours.
The number of seedlings can be increased with the help of hormonal drugs. Epin-Extra, Kornevin and Zircon copes well with this task. These drugs not only improve germination, but also possess others. properties:
- prevent the reproduction of pathogenic microflora;
- prevent the appearance of rot;
- promote the development of bacteria beneficial to plants;
- do not violate the phased (cyclical) development of culture.
To soak seeds in Epin-Extra, it is necessary to prepare a solution consisting of 8 drops of the drug and 200 ml of purified (no alkaline impurities) water. The seed must be kept in the stimulator for 2-4 hours.
Before use, Kornevin is also dissolved in water (1 g of powder per 1 liter of liquid). To achieve positive results, the soak time should be 16-20 hours.
To soak the seeds in Zircon, it is necessary to prepare a solution consisting of 1 ampoule of the drug and 1 liter of water. The seed product is kept in liquid for 10-15 hours.
