Gibberellin Powder CAS 77-06-5

Gibberellin Powder, also known as GA3 and 920, was discovered by Japanese pathologist Yingyi Kurosawa in 1926 when he was studying rice seedling cachexia. In 1938, a kind of active product was isolated from Gibberella Oryza in Japan. It was crystallized and named gibberellin (GA3)., More than 70 kinds of gibberellins have been isolated and identified, indicating that more than 40 kinds of gibberellins exist in higher plants. GA3, GA4) and ga7 are the most widely used and studied. This is a plant growth regulator with wide application and low toxicity. It is also one of the five plant endogenous hormones in agricultural objects (the other four are cytokinin, indoleacetic acid, abscission, and ethylene). Gibberellin in crops is called natural endogenous gibberellin, while gibberellin commonly used in agriculture is generally synthetic Exogenous Gibberellin. Gibberellin can accelerate the growth and development of crops. It can break seed dormancy, promote seed germination, promote early differentiation of flower buds, promote flowering and fruit setting, promote fruit development and increase fruit grain yield. Such an efficient and broad-spectrum plant growth regulator can be widely used in a variety of crop species and different growth periods.

What are the functions and applicable characteristics of gibberellin?

Gibberellin Powder can accelerate and promote the growth and development of crops, especially in stimulating cell elongation, lengthening stems, expanding leaves, promoting seed germination, inducing flower bud differentiation as soon as possible, accelerating the development and maturity of fruit stems, etc. at the same time, gibberellin can also improve the flowering and fruit setting rate, increase crop yield, and promote early fruit maturity The effect of delaying plant senescence time; In addition, for some crops that need low temperature and long light to differentiate flower buds or bloom, gibberellin can replace low temperature and long sunlight, so as to promote seed germination, early differentiation of flower buds and early opening of flowers.

Gibberellin has a very wide range of applications. It can be used not only in field crops such as rice, wheat, and corn, but also in cash crops such as cotton, soybean, and tobacco. It can also be widely used in all kinds of vegetable crops, eggplant crops, and all kinds of fruit trees. It can promote growth, bud, flower, and fruit.

In addition, gibberellin is mainly distributed in the new buds, young leaves, root tips, immature seeds, and fruits of crops. It is mainly synthesized in germinating seeds, growing buds and leaves, open flowers, expanded fruits, and growing roots, and is synthesized from the root upward through the skin tissue of crops From the top of the plant down to each vigorous growth and development part of the crop plant, it has certain differences in different crop types, different growth and development periods, different part content and transmission speed, and indifferent crop types, different crop varieties, different growth stages, different soil types The use concentrations and methods in different climatic environments are also slightly different. Only when used in a timely, appropriate, and appropriate manner can it promote the growth and development of crops. If the use concentration is too high or the dosage is too large, it is easy to cause crop overgrowth, deformity, albinism, inhibition of flower bud differentiation, inhibition of flowering, and other problems. If the use concentration is too small or the dosage is insufficient, It is difficult to play its due role, which we must pay attention to.

What is the use of gibberellin?

Gibberellin Powder and general pesticides can increase mutual efficiency. If you use too much gibberellin, the side effects can cause lodging, so you often use the Zhuzhuang hormone for regulation. Note: it cannot be mixed with alkaline substances, but it can be mixed with acidic and neutral fertilizers and pesticides. It can be mixed with urea for a better yield increase.

The spraying time after mixing with pesticides should be before 10:00 a.m. and after 3:00 p.m. if it rains within 4h after spraying, it should be sprayed again. The concentration of gibberellin is high, so please prepare it according to the dosage. If the concentration is too high, there will be overgrowth and albinism until deformity or death. If the concentration is too low, the effect is not obvious. The amount of liquid used for leafy vegetables varies with the size and density of crop plants. Generally, the amount of liquid used each time per mu is not less than 50kg. Gibberellin aqueous solution is easy to decompose and should not be put for a long time. It should be prepared and used now. The use of gibberellin can only play a good effect under the condition of a sufficient supply of fertilizer and water, and can not replace fertilizer.

Is gibberellin harmful to the human body? If so, what are the aspects?

Gibberellin Powder is a plant's endogenous growth hormone. A small amount of gibberellin will be produced at the growth top of any plant, so an appropriate amount of gibberellin will not do any harm to the plant itself, but will promote plant growth and development. For example, increase the yield of seedless grapes and break the dormancy of potatoes; When brewing beer, GA3 was used to promote the germination of barley seeds for maltose preparation; Gibberellin treatment could promote the heading of late rice when it was cloudy, rainy, and low temperature; Or regulating flowering period in hybrid rice seed production so as to meet parents' florescence. Due to the non-toxic nature of gibberellin and its extremely small residue in plants, the trace gibberellin entering the human body through the use of vegetables, melons, and fruits will not cause any harm to a humans health. On the contrary, it has been reported that taking the appropriate amount of gibberellin can treat diseases such as gastric ulcers and gastric mucosal damage. However, excessive use of gibberellin will cause the plant cell wall to become thinner and elongated, and the external manifestation is an overgrowth, which will reduce the lodging resistance of the stem.
