Gibberellin Acid Growth Hormone

Gibberellins (GAs) are a crucial class of plant hormones involved in various biological processes, such as plant growth and development. Gibberellins are named from GA1 to GA126, in the order of their discovery. In 1926, Eiichi Kurosawa of Japan discovered that rice infected with gibberella exhibited excessive growth, with the diseased plants often growing more than 50% taller than normal plants. Additionally, the seed setting rate was significantly reduced, leading to the name "foolish seedling disease". When scientists sprayed the filtrate from a gibberella medium on healthy rice seedlings, they observed that the seedlings exhibited symptoms similar to "foolish seedling disease", despite not being infected with gibberella. In 1938, Sadajiro Yasuda and Yusuke Sumiki of Japan isolated the active substance from the filtrate of the gibberella culture medium and identified its chemical structure, naming it gibberellic acid. In 1956, C. A. West and B. O. Feeney demonstrated the existence of gibberellic acid-like substances in higher plants. By 1983, more than 60 species had been isolated and identified. These substances are generally divided into two categories: free state and bound state, collectively referred to as gibberellins, named GA1, GA2, and so on.

Description

Introduction

Our product is a plant hormone, specifically a growth regulator, which plays a vital role in regulating various growth and development processes in plants. Gibberellic acid is a class of compounds consisting of more than 130 different diterpene acids, of which the most extensively studied and used is gibberellin acid (GA3).

Features

Promote plant growth and development
As a plant hormone, Gibberellin Acid Growth Hormone can significantly promote plant growth and development. It promotes the growth of plant stems, leaves and roots by activating the division and elongation of plant cells. Especially in the seedling stage of plants, it can accelerate cell expansion and nutrient absorption, so that plants can enter the growth stage faster.

Promote seed germination
Our product plays a vital role in the seed germination process. It can break the seed dormancy period, activate the enzyme system inside the seed, break down the stored starch and sugars, and provide enough energy for the seed to germinate.

Improve plant stress resistance
Gibberellin acid helps improve plant stress resistance when facing environmental stress (such as drought, cold or saline soil). It can enable plants to better adapt to harsh environments by regulating the water balance in the plant body and promoting root growth.

FAQ

Q: What is Gibberellin Acid Growth Hormone?

A: Gibberellin Acid (GA) is a plant hormone that plays a crucial role in regulating plant growth and development. It is involved in processes such as seed germination, stem elongation, flower and fruit development, and leaf expansion. GA is naturally produced in plants, but it can also be applied externally to enhance growth.

Q: What are the benefits of using Gibberellin Acid Growth Hormone in plants?

A: Gibberellin Acid promotes various aspects of plant growth, including faster seed germination, increased stem elongation, and enhanced flowering and fruiting. It can also help break dormancy in seeds and buds, improve fruit size and yield, and promote stronger root development, especially in crops like grapes, tomatoes, and rice.

Q: How does Gibberellin Acid affect seed germination?

A: Gibberellin Acid plays a key role in breaking seed dormancy by stimulating the synthesis of enzymes that help break down stored food in seeds, making it available for growth. This results in quicker and more uniform seed germination, which is particularly useful in agricultural practices and for crops with hard-to-germinate seeds.

Q: How should Gibberellin Acid Growth Hormone be applied?

A: Gibberellin Acid is typically applied as a foliar spray or soil drench, depending on the plant species and desired effect. The hormone is diluted with water according to the manufacturer's instructions. For foliar application, it is sprayed directly onto the leaves, while soil drenching involves watering the base of the plant. Application timing and dosage should follow specific recommendations for optimal results.

Q: Are there any risks or precautions when using Gibberellin Acid?

A: While Gibberellin Acid is generally safe when used correctly, excessive application can lead to undesirable effects, such as excessive stem elongation (leading to weak plants) or delayed flowering. It's essential to follow recommended dosage instructions carefully. Overuse can also disrupt the normal development of fruits and flowers, so applying GA at the right growth stages is critical.
