1、Brassinolide and gibberellin promote grape fruit development and

Brassinosteroid (BR) and Gibberellins (GA) are important hormones that significantly influences grapeberry development and ripening. In the present study, grape clusters were soaked separately with EBR (Epi brassinolide), GA 3, and EBR+GA 3 during fruit development.

2、Comparative effect of gibberellic acid and brassinolide for mitigating

This study explores the potential of foliar-applied gibberellic acid (GA 3) and brassinolide (BR), individually and in combination, to enhance the drought resilience in pea plants.

3、Seed Dressing Containing Gibberellic Acid, Indole

In this study, we investigated a seed dressing containing 0.136% gibberellic acid (GA), indole-3-acetic acid (IAA)-, and brassinolide (BL) as a wettable powder (WP), hereafter referred to as GA-IAA-BL WP.

4、How Many Times Can Brassinolide and Gibberellic Acid Be Applied Daily?

Brassinolide and gibberellic acid are plant growth regulators primarily used to promote plant development and increase crop yields. When using these substances, it is essential to follow proper usage methods and dosages to ensure effectiveness and safety.

5、Synergistic Effects of Gibberellic Acid, Forchlorfenuron, Thidiazuron

To investigate this, we evaluated the effects of five plant growth regulators—gibberellic acid (GA), 24-epibrassinolide (EBR), forchlorfenuron (CPPU), thidiazuron (TDZ), and streptomycin (SM)—on two grape varieties ‘Shine Muscat’ and ‘Red Muscat of Alexandria’.

Gibberellic acid + Brassinolide can preserve flowers, preserve fruit

Generally, it is used when 2/3 of the flowers are withered, and the commonly used concentration is 50~100ppm, which can be sprayed together with the pesticides for pests and diseases.

Altogether, 8 treatments were given as foliar spray including two types of control - namely water spray and no spray.

Differences Between Brassinolide and Gibberellic Acid

Brassinolide and gibberellic acid are the two most commonly used regulators for citrus flowers and fruits. Some growers trust brassinolide, while others are used to using gibberellic acid.

Application of homobrassinolide enhances growth, yield and quality of

Brassinosteroids (BRs) have emerged as pleiotropic phytohormone owing to their wide function in crop growth and metabolism. Homobrassinolide (HBR) being an analogue of BRs is known to improve the growth, yield and quality parameters in many crop plants.

Brassinolide (Beta-naphthoflavone) and gibberellic acid (Glucotrol) are both plant growth regulators primarily used to promote plant growth and increase yield. They can be applied individually or in combination to enhance effectiveness. In practice, the decision to use these compounds together depends on factors such as crop type, growth stage, and soil conditions.

I. Pharmacological Effects of Brassinolide and Gibberellic Acid

1. Brassinolide: A plant hormone that stimulates cell division and elongation, increases chlorophyll content, and improves photosynthetic efficiency, thereby accelerating growth and boosting yield. It also promotes flower bud differentiation, enhancing flower quantity and quality, particularly in fruit trees and vegetables.

2. Gibberellic Acid: A synthetic auxin-like compound with physiological activities similar to brassinolide. It promotes cell division, elongation, and chlorophyll synthesis, while improving photosynthesis. Like brassinolide, it enhances flower bud differentiation and is widely used to improve growth in fruits and vegetables.

II. Application Methods for Brassinolide and Gibberellic Acid

1. Individual Use: Both compounds can be applied separately. it is generally recommended to use one before the other due to differences in their mechanisms. For example:

   • Brassinolide: Spray during fruit development in fruit trees to promote growth.
   • Gibberellic Acid: Apply to soil after sowing or transplanting in vegetables to increase yield.

2. Combined Use: In specific cases, combining the two may enhance results. For instance:

   • Fruit Trees: Use brassinolide first to promote fruit growth, followed by gibberellic acid to improve color and quality.
   • Vegetables: Apply gibberellic acid initially to boost yield, then use brassinolide to strengthen plant health.
   • Timing and Method: Adjust application timing and methods based on crop type, growth stage, and soil conditions.

III. Precautions

1. Dosage: Follow recommended doses and application methods in product manuals. Excessive use may cause rapid, uncontrolled growth, compromising fruit quality and yield.

2. Monitoring: Observe plant responses during application. Discontinue use and consult professionals if abnormalities arise.

3. Avoid Overuse: Prolonged or excessive use of these hormone-like substances may negatively impact plants. Use cautiously to prevent misuse.

4. Combination Risks: Be aware that differences in mechanisms between the two compounds might reduce efficacy when combined. Adjust strategies based on practical outcomes.

Brassinolide and gibberellic acid are effective plant growth regulators that can be used individually or in combination. Always adhere to product guidelines, monitor plant reactions, and avoid misuse to optimize results.
