It is difficult to imagine a person who would not love tomatoes. It is for this reason that many dachas grow on their plot these delicious and healthy vegetables. Way to produce a rather long. It is impossible to get it without high-quality seed.
What is the shelf life is provided for tomatoes, how much time seeds retain their characteristics, about the nuances of storage and other factors will be going to talk today.
How many years of tomato seeds retain their germination?
Tomatoes are considered a useful and valuable product. Considering these qualities, the majority of the gardener annually plant this culture on their sites. Seeds stored in suitable conditions are used for sowing. Purchasing seeds, you need to find out how good they are for landing. According to the requirements of the Ministry of Agriculture of 1999, the final expiration date should be specified on packaging with seeds. Many factors affect the safety of seeds, the container itself also plays, in which they were.
In paper converters can be stored one year. When placing seeds into foil packages or in double packages that do not pass by moisture, this term increases to two years. The germination of seed material according to GOST should not be less than 95%. Purchasing shopping products sealed in plastic bags, it is advisable to pour it into breathable paper envelopes. On the middle, seeds of this culture will not lose weight about 5 years and more. When stored for more than 7 years, their quality is significantly reduced. To check their quality, it is not necessary to navigate the date indicated on the pack. In this case, it is recommended to do the test and check how long the seeds.
To check their germination, you need:
- Take a flat container;
- Use a thin material folded several times;
- Moisten it, and the seeds pour out between the layers;
- to wear a cellophane sachet on the container;
- Leave the container in a warm place, while you need to monitor the temperature regime (the temperature is optimal +25 degrees).
It is necessary to inspect the container, check if paper did not dry. If necessary, it will be moistened. After 4 or 5 days the sprouts should appear. It is important to make sure their number exceeds 30%. If sprouts appeared very little (less than 30%), such a sowing material is no longer suitable for use. Having done a similar test, it is better to sign bags, indicating the percentage of shoots. Planting seeds into the soil, you need to consider how well they rose. With a small percentage, it is necessary to increase the amount of material for sowing.
Many dackets prefer to use seeds collected independently. It will save them from unreasonable spending, besides, bushes grown from the assembled material will be more adapted to the place of growth and the climatic zone. When collecting, it should be borne in mind that from the hybrid seeds of seeds is not recommended, because it is not clear that they can grow. Tomatoes refer to self-polishing cultures, so it is better to use seeds from varietal species. Collecting high-quality material, it is worth staying on large, ripe, elastic and fleshy fruits. For a collection, the tomatoes are suitable, which caused the first.
From the bush remove a slightly misunderstood with a characteristic color for the variety. Restored tomatoes are not used to collect material. In the greenhouses, vegetables are removed from the 2nd brush, in the beds – with the 1st brush. Collection of planting material produced with healthy bushes. Rude fruits It is recommended to leave for the ripening. Then the ripe fruit must be cut across and squeeze out of them seeds in the prepared container with water for several days. After that, they are kneaded and dried.
Storage of material should be held in compliance with the rules. In dry non-refined premises, the seeds will start to push, in a wet place they will germinate. All these factors are undesirable and sometimes destructive.
From compliance with the storage conditions will depend on the content of seeds to their landing, which directly affects the germination and development.
- The seed fund should be stored in glass jars closed with covers. It is important to protect them from the effects of sun rays and light. You also need to remove the material from heat sources in the form of batteries, furnaces, fireplaces.
- For storage is more suitable Dry, darkened place.
- At home, the collected grains for landing are kept in paper envelopes. They are recommended to immediately sign, indicating the collection period and the name of the variety.
- Seeds will be best saved In compliance with the temperature regime from 6 to 12 degrees of heat, with a relative humidity of 55%.
There is an opinion that tomato grains can be left for storage in the refrigerator, on its lower part. A good place for this can be a cool dry veranda. Choosing one of the same options, it should be remembered that the seed fund requires a careful relationship, and with sharp temperature differences or with high humidity, it may simply spoil.
In winter, you should view the material, if necessary, remove the resembling seeds, and the preserved use to disemboditate.
Is it possible to plant an overdue material?
Sometimes many daches find already old seeds with long expiry date, not knowing whether it is worth using them. According to experts, the preservation of the seed fund is more affected by its correct storage. If the temperature is optimal for tomatura, keep the grains in a suitable capacity, to revise the seed fund, then it is possible and in 5-6 years to get a germination of about 60%. It was recommended even the seeds of tomatoes, which were already more than 10 years. True, such shoots can germinate a little later, but the condition of the fruit and the quality of the crop does not affect.
When expired, it is recommended to produce a massive landing, it will determine the quality. In the event that this indicator is not lower than 50%, the material can be used. Seeds from proven producers can give an 80% and higher. According to experienced agronomists, it is not worth throwing out the goods with an expired term. You can try to increase their norm when sowing or use growth stimulants. For these purposes, the ash is suitable or aloe juice, succinic acid. Increase the germination of tomatoes will help their soaking. You can use for this hydrogen peroxide. For its preparation take:
- peroxide (3%) – 10 ml;
- Water – 90 ml.
They make soaking immediately before planing seeds, dipping them in 3% solution of hydrogen peroxide for 2-3 days before the appearance of sprout. It is necessary that the liquid only slightly covered the grains. After that, they are planted, including seedlings. In this case, the peroxide will contribute to the acceleration of germination, stimulate growth. The old material for planting, the more time it will be necessary for its soaking.
“Revitalize” grains will allow and pre-wigure them in stimulants for growth. These may be drugs “Zircon”, “Eopin”, “Epin”. For this, they are lowered into ordinary water for several hours, then poured with a solution prepared from the drugs described. For the stimulator, you will need to take 100 ml of water and add 1 ml of the selected tool to it. Seeds are placed in a means of 6-8 hours. In the soil, the seeds are planted with dry if the air temperature did not harde down above 10 degrees.
Warming up to 15 degrees makes it possible for landing in the soil of clumsy seeds.
