6-BA Cytokinin Plant Hormone

Cytokinin (CTK) is a plant hormone isolated or synthesized from corn or other plants. It is generally produced in the roots of plants and is a class of substances that promote cytokinesis and stimulate the differentiation and growth of various tissues. It has a synergistic effect with auxin. Cytokinin is a plant hormone that regulates the growth and development of plant cells. It plays an activating role in cell division and is also involved in cell growth, differentiation, and other related physiological activities, such as kinetin (KT), zeatin (ZT), and 6-benzylaminopurine (6-BA). Cytokinins are a class of plant hormones that promote cell division, induce bud formation, and stimulate growth. The term "cytokinin" is derived from cytokinesis and is mainly distributed in the parts of cell division, such as stem tips, root tips, immature seeds, germinated seeds, and growing fruits. When it was first discovered, cytokinin was also called "cytokinesin." In 1955, when Skoog et al. in the United States studied plant tissue culture, they discovered a substance that promotes cell division, which was named kinetin. Its chemical name is 6-furfurylaminopurine (KT), and the pure product is a white solid, soluble in strong acids and alkalis. Kinetin is not naturally present in plants. Later, more than a dozen substances with physiological activity similar to kinetin were isolated in plants. Now, all substances with the same physiological activity as kinetin, whether natural or synthetic, and including synthetic plant growth regulators, are collectively referred to as cytokinins. Their basic structure includes a 6-aminopurine ring. The natural cytokinins in plants include zeatin (ZT), dihydrozeatin, isopentenyladenine, zeatin nucleoside, isopentenyl adenosine, and others. The root tip is the primary site of their synthesis in the body. In addition to kinetin, synthetic cytokinins also include 6-benzylaminopurine (6-BA) and others.

Description

Introduction

The 6-BA Cytokinin Plant Hormone is a synthetic plant hormone of the cytokinin class, widely used in agriculture, horticulture, and plant tissue culture. It plays a key role in regulating plant growth and development by promoting cell division, initiating shoot formation, and delaying senescence.

Applications

Promote Cell Division and Differentiation
6-BA significantly stimulates plant cell division, particularly in rapidly growing tissues such as meristems. It is commonly used to induce bud formation in tissue culture, enabling rapid plant propagation.

Induce Adventitious and Lateral Bud Formation
In plant in vitro culture, our products are often used in combination with auxins to control the direction of bud differentiation. They help break apical dominance, promote the formation of lateral or adventitious buds, and support plant multiplication and fast seedling cultivation.

Delay Leaf Senescence
The 6-BA Cytokinin Plant Hormone can delay leaf yellowing and aging by inhibiting chlorophyll degradation. This extends the photosynthetic period of leaves and helps improve yield. They are especially effective in the production of leafy vegetables and ornamental foliage plants.

Regulate Fruit Development and Extend Shelf Life
Spraying 6-BA on certain fruit trees (such as grapes and apples) promotes fruit enlargement, increases individual fruit weight, and delays ripening. This helps manage harvest timing and improves fruit quality. Additionally, it can be used post-harvest to slow aging and extend shelf life during storage.

Promote Flower Bud Differentiation
6-BA is also used to regulate flower bud formation and support the differentiation and development of floral organs. It is widely applied in the flower industry to increase the rate of bud formation and the total number of flowers.

FAQ

Q: What is 6-BA and what type of hormone is it?

A: 6-BA (6-Benzylaminopurine) is a synthetic plant hormone belonging to the cytokinin class. It is widely used to promote cell division, regulate growth, and delay senescence in plants.

Q: How does 6-BA promote plant growth?

A: 6-BA stimulates cell division and differentiation, especially in meristematic tissues. It also promotes shoot initiation, breaks apical dominance, and encourages the formation of lateral and adventitious buds.

Q: In what areas of agriculture is 6-BA commonly used?

A: 6-BA is used in agriculture, horticulture, and plant tissue culture. It is applied to leafy vegetables, fruit trees, ornamental plants, and during in vitro propagation to enhance growth and yield.

Q: How does 6-BA affect fruit development and preservation?

A: When applied to fruit trees such as grapes and apples, 6-BA promotes fruit enlargement, increases individual fruit weight, and delays ripening. It also helps extend shelf life during storage.

Q: What is the role of 6-BA in delaying leaf senescence?

A: 6-BA delays leaf senescence by inhibiting chlorophyll breakdown, which prolongs the photosynthetic activity of leaves. This contributes to higher productivity, especially in leafy crops.
