ABA Abscisic Acid Plant Hormone

Abscisic acid is an organic substance with the chemical formula C15H20O4. It is a growth-inhibiting plant hormone named for its ability to cause leaves to fall off, and may be widely distributed in higher plants. In addition to promoting leaf shedding, it also has other functions, such as inducing bud dormancy and promoting potato tuber formation. It also inhibits cell elongation. In 1965, it was confirmed that abscisin II and hypnosin are the same substance, and they are uniformly named abscisic acid. Abscisic acid is a plant hormone with a sesquiterpene structure. In 1963, Eddicott et al. purified a substance from cotton bolls that can significantly promote the shedding of petioles of cotton seedling explants, called abscisin II. Welling et al. in the United Kingdom also purified a substance from maple leaves under short-day conditions, which can control the dormancy of deciduous trees, called hypnosin.

Description

Introduction

The ABA Abscisic Acid Plant Hormone is a plant hormone that plays a crucial role in regulating various physiological processes in plants, including growth, development, and stress responses.

Features

Efficient regulation of plant growth
Our product is one of the five classic endogenous hormones in plants, and is on par with gibberellins and auxins, and has a comprehensive regulatory effect on plant growth and development. It can inhibit the elongation growth of plant cells, slow down the growth rate, and help plants save energy and resources under adverse conditions. At the same time, this product can also promote the closure of plant stomata, reduce water transpiration, and improve the drought resistance of plants.

Enhance plant stress resistance
The ABA Abscisic Acid Plant Hormone is called "stress hormone" and plays a core role in plants' response to drought, salinity, low temperature and other stresses. It can activate stress-related genes in plants, such as LEA proteins, antioxidant enzymes, etc., enhance the osmotic regulation ability of cells, and improve the stress resistance of plants.

FAQ

Q: What is ABA (Abscisic Acid) and how does it affect plants?

A: Abscisic acid (ABA) is a plant hormone that plays a critical role in regulating plant growth and responses to environmental stress. It helps control processes such as seed dormancy, stomatal closure, and drought resistance, enabling plants to adapt to changing conditions.

Q: How does ABA help plants cope with water stress or drought?

A: ABA triggers the closure of stomata, which are pores on plant leaves, reducing water loss through transpiration. It also promotes the synthesis of proteins that help the plant maintain hydration and protect against dehydration during periods of water scarcity.

Q: In which stages of plant growth is ABA most active?

A: ABA is especially important during seed dormancy, germination, and stress responses. It regulates the transition from seed dormancy to germination, and its levels increase in response to environmental stresses like drought, high salinity, and low temperatures.

Q: How is ABA applied to plants for growth regulation?

A: ABA can be applied as a foliar spray or soil drench. Commercial formulations of ABA are available for agricultural use, where it is used to induce dormancy in seeds, regulate fruit ripening, or manage water stress in crops.

Q: Which crops benefit most from ABA application?

A: Crops that experience environmental stress, particularly those grown in areas with water scarcity, such as grapes, citrus, cotton, and cereals, can benefit from ABA application. It helps improve drought tolerance, fruit setting, and overall plant resilience.
