Auxin: application in crop production, preparations based on them

Anonim

Auxins are plant hormones that are considered indole derivatives. They are characterized by high physiological activity. With the help of products based on these substances, it is possible to activate the growth of fruits and shoots of crops. If the concentration of auxin in the plant decreases, its foliage begins to wither. To prevent such problems, it is recommended to use special preparations made on the basis of auxins.

What effect do auxins have

These substances are responsible for the growth of roots and the redistribution of useful elements in plants. Their distinctive feature is the ability to spread through the tissues. This effect is achieved through sap flow.

Substances provide apical dominance. This means that the shoot grows stronger upwards than bushes. In this case, the roots, on the contrary, grow downward. This helps them to get moisture from the lower soil structures.

The most common auxin is considered to be heteroauxinic acid. Chemists have learned to synthesize this substance artificially. Phytohormones take part in important processes. They help to get the following results:

  1. Activate cell growth during active formation. This allows you to maintain the elasticity of the tissues. Auxin deficiency is indicated by wilting foliage.
  2. Stimulate the formation of cambial tissue, which is placed under the outer shells. Cambium ensures the transfer of beneficial elements that are produced by the leaves and move to the roots.
  3. Coordinate the interaction of different plant organs. This effect is achieved by moving phytohormones.
  4. Speed up the regrowth of hairy roots. They help to absorb useful elements from the soil. The formation of root shoots affects the survival of crops during planting and accelerates their growth after stress. These include prolonged rainfall, dry weather, high humidity, temperature fluctuations, the development of diseases and attacks of harmful insects.

Auxins do not belong to the category of fertilizers or plant protection products. At the same time, they have a pronounced auxiliary effect when feeding and treating crops from diseases and parasites.

What plants do they need?

Such products are suitable for processing different crops. The positive effect is achieved depending on their variety:

  1. When processing fruit plants, it is possible to minimize the amount of carrion and improve the quality of the fruit. At the same time, auxins should be used in doses so that they do not impoverish the soil.
  2. Soaking beetroot, tomato or carrot seeds in an auxin solution increases germination parameters and makes plants more resistant to parasite attack and disease development.
  3. Increased dosages of auxins help to cope with weeds. At the same time, the substances do not harm cultivated plants.

Benefits and application rules

The use of such substances in crop production has the following advantages:

  • increasing plant resistance to adverse climatic conditions;
  • strengthening crop immunity;
  • full development of plants;
  • high productivity;
  • increase in yield and fruit quality;
  • prevention of accumulation of harmful elements in any kind of fruits, vegetables and berries;
  • reducing the cost of fertilizers and expensive crop protection products.

Phytohormone-based preparations must be used correctly. An overdose of auxins slows down the growth of crops.

With the advent of spring, the flowering of individual fruit trees may coincide with the onset of return frosts. As a result, flower buds freeze out without forming an ovary. To delay the moment of blooming flowers, plants need to be treated with a concentrated solution of auxin-based preparations. In this case, substances inhibit important processes.

After using phytohormones, fruit trees freeze for a certain time. However, with the onset of favorable conditions, the development and flowering of crops resume again. This helps prevent crop losses.

Auxin-based drugs

There are a lot of auxin-based products on the market today. The most effective remedies in this category include:

  1. "Kornevin" - promotes the rooting of plants after planting seedlings of herbaceous crops, cuttings, seedlings of tree species in vegetative breeding. With its help, it is possible to activate the growth of young shoots. In addition, the substance allows you to minimize the negative impact of stress factors.
  2. "Heteroauxin" - used in the same way as "Kornevin". A distinctive feature of this tool is considered to be a faster effect. However, it lasts less.
  3. "Kelpak" - is a system growth regulator. It includes 7 varieties of auxins. In addition, the composition contains 12 types of other plant phytohormones. This helps to achieve a combined effect on crops.
  4. "Gulliver" is a combined remedy. It contains phytohormones and succinic acid.

Safety precautions

In order for auxin-based preparations not to harm the body, when using them, safety rules must be observed. You need to work with the means in individual protective equipment - glasses, a respirator, gloves.

For the manufacture of a working solution, it is forbidden to use dishes that are used for food products. Do not eat, drink or smoke while processing plants. After completing the procedure, you need to take a shower and change clothes.

Compatibility

Auxin-based products can be combined with many fungicides and insecticides. To assess compatibility, you need to mix 2 products in small volumes. If sediment or flakes appear, it is better to refuse to use the composition.

Auxins are effective plant hormones that activate growth processes. In order for drugs based on such drugs to give an effect, they must be used according to the instructions.
