Expiry date of pepper seeds
The germination of pepper seeds depends on the storage conditions: temperature, humidity, the presence of a number of aggressive substances, the possibility of infection by fungi, mold and other destabilizing influences that can spoil the seed material before it is useful for its intended purpose.
Influencing factors
Factors affecting the germination of pepper seeds are as follows.
- With long-term (more than 25 days) exposure and long-term (more than 2 seconds) heating of seeds in water with a temperature of about 55 degrees, as well as if the conditions for their sowing are violated, germination decreases sharply.
- Seed material that has lain for half an hour or an hour in water with a temperature of 26-28 degrees can be sown for 20 days, and immersed in water with a temperature of 36-38 degrees (at the same time) - 3 days.
- Pepper seedlings, obtained under conditions other than those recommended, appear only after a few days.
- During the preprocessing period, it is necessary to monitor the moisture and temperature of the seed stocks. If the humidity is insufficient, the embryo becomes lethargic and sometimes dries up.
- If the humidity is too high, the seeds often grow moldy and lose their germination: the embryo rots and dies.
- Monitor storage temperature. An interval from -1 to +30 is allowed, with a significant violation of this condition, the seed material easily becomes unviable.
- Moderate moisture is achieved by carefully monitoring the temperature around the seeds. Storing them in airtight conditions also helps, for example, in a sachet or jar with a ground stopper.
There are cases that a weakened embryo gives unstable shoots that cannot fully develop further, as a result, the plant dies without bringing any harvest.
How long can seeds be stored?
Seeds of bitter and sweet (Bulgarian) peppers are preserved with proper use for at least a year. For comparison: seeds of cucumbers, eggplants and tomatoes are good for 3 years. The conscientious manufacturer will necessarily indicate the expiration date and collection period.
Most vegetable crops require 7 to 40 days to germinate successfully, depending on temperature and humidity. In a greenhouse or greenhouse, this process can be significantly accelerated: there is no sharp overheating of the soil due to the light-scattering walls of the protective structure. The soil is not exposed to a constant and massively intensified attack by weeds.
Seed germination increases with moderate light. Only ripe, healthy and undamaged peppers are suitable for seeds, and they must be harvested by hand. The material must be dried before sowing. On average, the germination rate of freshly harvested grains is 80-95%. The seeds can be dug up after they have sprouted. The germination rate of these grains during transplantation will average 70%. After a few days, they can be transplanted to the garden bed.
The seeds must be sorted before sowing. To do this, they are scattered in paper bags and determined for germination. Seeds that have greatly lost in size or darkened are best discarded: defective pacifiers will definitely not germinate. They do not sink in a glass of water.
The maximum period of preservation of embryos in seeds is no more than 3 years, after this time, only 30-40% of all harvested units remain alive, therefore it makes no sense to keep them for future use.
Can expired material be planted?
Pepper seeds planted for 4-5 years sharply reduce the percentage of germination. It will be no more than 10% at best, while at worst it is pointless to wait for the harvest. Taught by the bitter experience of previous generations of summer residents, modern gardeners do not waste time on obviously useless work: trying to germinate old seed. It is not recommended to use specimens collected more than 2-3 years ago for sowing and cultivation.
Recently, scientists have learned how to get high yields using old pepper seeds: they store a lot of nutrients, but they require careful maintenance.
However, this approach requires almost laboratory conditions, protected from destabilizing environmental factors.
Expired material is suitable for planting if, in the last three years, seeds that do not inspire confidence have appeared on the nearest counters. For example, a variety that resembles the tomato F1, does not produce self-propagating seed, which can be restarted as many times as necessary in a greenhouse environment.
Most summer residents claim that old pepper seeds are not suitable for seedlings. But you can always remember that aged, stale grains someday will surely sprout. This is very economical: planting material is usually not cheap. To select viable specimens, do the following. Wait for stable and warm weather in spring.
If you have a full-fledged greenhouse with the ability to control the microclimate, then this step can be skipped.
- Soak the seeds for half an hour in warm water (30 degrees).
- Wrap in a cloth and place in a plate, moisten them periodically, but do not flood. They must breathe, not suffocate.
- Keep them in a warm (+20 degrees) place away from direct sunlight for a week.
- Having achieved seedlings, carefully transplant them into the ground. Discard grains that have not sprouted.
Subsequent care for freshly planted peppers must be provided in full: daily watering, regular feeding of plants and spraying them with folk remedies for pests.
