Plants hormones are very important in regulating growth in plants. They control and modify a number of plant processes such as elongation of stems, formation of leaves and flowers, cross between the two, development and ripening of fruit etc. People have started recognizing their importance and nowadays, plant growth regulators are widely used to control various plant processes. Different growth regulators stimulate different plant responses. They were first used in the USA, Ethylene being the first plant growth regulators to be discovered. Since then, plant growth regulators are widely used and have become an important part of modern agriculture.

Ethylene is one of the best known examples of plant growth regulators. This hormone plays an important role in ripening of different types of fruits, such as apple, banana, pear and melons. It is produced naturally by ripening fruits and one can also produce them synthetically from sources such as Ethephon. Ethylene produced by ripening apple can speed up the ripening process of bananas, when put together in the same paper bag. Another important plant growth hormone is auxin, which was first identified in 1930s. Later many synthetic auxins were also developed which are used for a number of purposes such as promoting root initiation, prevention of fruit drop in apples. It can also induce growth in pre-existing roots as well as adventitious roots.

Giberellic acid

Gibberellic acid (GA) is a very important plant growth regulator and even applications of very low concentrations can have profound effects on the growth of plant. It is also used as seed dormancy breaker and is most effective on rosette plants that have cold dormancy requirements for germination. Hormone is also known to improve growth of young plants that are produced from seeds, cuttings, or plugs. It is very effective on plants suffering nutrient deficiencies. Farmers, hobbyists or anyone who grows plants can now buy Gibberellic acid (GA) powder online at discounted prices. The powder is easy to mix, use and can be applied on plants growing anywhere.

Fulvic acid for plants

Fulvic acid has a positive effect on the overall growth and development of crops. It is known to stimulate plant metabolism and increase stress tolerance in plants. It also increases enzyme activity and act as a catalyst in plant respiration. One can buy best quality Fulvic acid samples online. They do not precipitate when mixed with water and can be used for as many as three years.
