What conditions are necessary for germination of seeds? Temperature for germination of seeds

Novice gardeners should know what conditions are necessary for the germination of seeds. One land and water is not enough to prepare future seedlings. The surrounding space must correspond to the parameters of the life of a particular plant. In nature, take into account the season, the terrain, and also mount the greenhouses if necessary.

Environment and region

Before you begin to determine what conditions are necessary for seed germination, it is required to know whether a plant can live in this area. You can grow it at home, but suddenly it will stretch to a huge size ... Therefore, you need to familiarize yourself with the description of the properties of the chosen culture and the features of planting. Take into account the structure of the soil, the number of irrigation per day, the addition of fertilizing in the soil.

Often, these points differ when considering the question of what conditions are necessary for the germination of seeds of exotic plants. In the northern regions, they can grow only in conditions of a greenhouse. In the southern nature is more favorable, they can be planted in open beds. But no one can give guarantees of normal growth if the required regulations were not observed.

In the latter case, another important factor is the number of sunny days per year. This is not forgotten to consider when considering the question of what conditions are necessary for the germination of seeds. Therefore, the planting site is equipped with special fluorescent lights that perform an additional function - heating the soil. Temperature is very important when getting small sprouts of a new plant.

What is needed?

Consider what factors are important for the germination of seeds at home. Not every plant grows even with proper care. By creating the necessary conditions, they increase their chances of survival. For intensive growth requires:

1. Fertile soil - is sold in a specialized department of gardener in hypermarkets or a flower shop. It must meet the safety requirements for humans, be treated against pathogens. Often the packaging describes the composition of the mixture.
2. A certain temperature is often above room temperature.
3. The air is clean, unreleased.
4. The absence of powerful emitters of electromagnetic and thermal waves.
5. Sufficient sunlight or artificial light per day.
6. Feeding the soil with water and minerals.

Air

Seed germination conditions necessarily imply the presence of oxygen. It participates in the metabolic processes of all living cells. For plants, its presence is vital. Sprouts are pulled out of the earth, consuming a huge amount of air. With its shortage, the process of cell development slows down considerably, and if it is completely absent, the necrosis of the plant may begin.

Oxygen is important not only for plants, but for any living being. It is not recommended to use candles and other open fire in a room with seedlings. If you have to do this, you should often ventilate the room. When the soil is covered with a film, the seeding site is not tightly clogged. Air should flow to the surface of the soil.

Shine

The sun's rays are the basis of all life on Earth. All plants tend to skyward, to the sun, and the growth rate depends on the constant lighting. For seed germination, this factor must be taken into account. Special lamps are produced that are substitutes for natural light.

At night, plants produce carbon dioxide. Therefore, it is not recommended to place sprouts in sleeping rooms. With a large number of indoor plants, the head often suffers from the shortage of oxygen in the morning. It is necessary to ensure a constant flow of air to the soil with seeds.

In total darkness, some growth of plants is still observed. But the sprouts obtained are not capable of further development in full. They become fragile, lifeless. The color of their leaves is closer to yellowish than to green shades.

Water

What does biology say? Germination of seeds is arranged in such a way that the basic forces for dividing cells are drawn from water. Chemical processes can not pass without a liquid, so you should plan to water the seedlings. Often give seeds to germinate without the earth, in the water. This process is less time-consuming. As soon as the first roots have appeared, they plant the seedlings in the soil.

The plant consists, like the human body, mostly of water. It feeds the cells with necessary minerals, participates in the metabolism and growth processes, displays the products of decay. Thanks to the liquid, the nutrients dissolve in the soil. But under the influence of heat, the seeds can germinate at the storage stage.

To do this, they need high humidity, light and a comfortable temperature. However, in the memory of plants there is a mechanism that perceives the seasons. So, with a thaw in the spring, seeds begin to grow even in the total darkness of the basement. They are able to perceive the change of seasons.

Heat

Active growth occurs when the temperature for germination of seeds is above 20 degrees Celsius, ideally - no lower than 25. Cold tightens the process of growing seedlings. Southern regions are rich in vegetation, its diversity is sometimes striking. This is due to the warm climate that provides intensive cell growth.

In the northern regions vegetation freezes with the arrival of cold weather. Only with the arrival of heat, everything comes to life again. The room is always a plus temperature, so the main concern is to ensure the correct lighting. The effect of low temperatures can be checked by placing a vessel with seeds in the refrigerator. The process of their growth will significantly slow down.

If, under the influence of warm sunlight, the first shoots appear the next day or by evening, then in the cold place, at a temperature not exceeding +3 degrees, the first signs of growth can be seen only after five days.

Additional measures

Conditions for germination of seeds should be observed in any case, then it will take a minimum of time to obtain healthy seedlings. Additional measures are the creation of a favorable soil composition for the growth of a particular plant species. Some cultures require a certain (neutral, weakly acidic or otherwise) growth medium. The pH value is important here. More often its value is in the range from 5 to 8.

Plants do not like water stagnation, so it is not recommended to water the seeds profusely. Taking into account the removal of excess moisture from the soil. Under the pots, small holes are made. The upper layers of the soil periodically loosen to penetrate oxygen through the water-compacted earth.
