1、Gibberellic acid + Brassinolide can preserve flowers, preserve fruit
When there are too many flowers and too many weak flowers, we can spray brassinolide + phosphorus potassium boron fertilizer after 2/3 of the flowers to improve the quality of the flowers.
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、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.
The activity and interaction of brassinolide and gibberellic acid
Gibberellic acid showed an additivity relationship with low concentrations (10−9–10−8M) of brassinolide in this test system and the two growth promoters may therefore act independently at the cellular level.
The activity and interaction of brassinolide and gibberellic acid in
The growth rate of mung bean epicotyls was used for evaluating the effect of brassinolide on cell elongation. Growth above that of control plants was observed at 10−10M and above.
Effect of Brassinosteroids and Gibberellic acid on parthenocarpic fruit
Based on this research combined application of 1000 mg /L GA3 plus 0.5 mg /L BRs had positive effect and therefore can be recommended for spray on sugar apple in order to obtain seedless fruit with high quality, so, it can be used as an alternative to hand pollination.

Brassinosteroids and gibberellic acid: effects on in vitro pollen
In this study, the effects of two brassinosteroid compounds, epibrassinolide and 22S,23S-homobrassinolide, and gibberellic acid (GA 3) on in vitro pollen germination of two table grape cultivars, ‘Italia’ and ‘Cardinal’ (Vitis vinifera L.), were determined.
Comparative effect of gibberellic acid and brassinolide for mitigating
Comparative effect of gibberellic acid and brassinolide for mitigating drought stress in pea (Pisum sativum L.)
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. Below is a detailed guide on their application, precautions, potential side effects, and mitigation measures:
I. Application Methods for Brassinolide and Gibberellic Acid
-
Timing of Application: Apply during critical growth stages, such as before/after sowing, pre-/post-flowering, and fruit enlargement periods. These phases correspond to rapid plant growth, where the regulators can effectively enhance development.
-
Dosage: Adjust dosage based on crop type, growth stage, and soil conditions. The typical range is 100–300 grams per mu (0.067 hectares). Excessive use may lead to overly rapid growth, compromising yield and quality. Always refer to product guidelines or consult professionals.
-
Application Methods:
- Spraying: Suitable for large-scale crops (e.g., fields).
- Drip Irrigation: Ideal for trees, flowers, or orchards.
- Foliar Application: For vegetables, fruits, or direct leaf spraying. Ensure even distribution on leaves and stems, avoiding direct contact with roots.
-
Combination with Fertilizers: Mix with nitrogen, phosphorus, or potassium fertilizers to optimize results. balance proportions to prevent nutrient imbalance.
-
Precautions:
- Avoid mixing with alkaline substances (reduces efficacy).
- Do not apply continuously for extended periods (risk of plant resistance).
- Minimize environmental pollution by preventing residue runoff into soil or water sources.
II. Side Effects and Mitigation Measures
-
Allergic Reactions: Skin itching, redness, or respiratory issues may occur in sensitive individuals. Discontinue use immediately and seek medical attention if symptoms arise.
-
Growth Suppression: Overuse may inhibit plant growth. Adhere strictly to recommended doses and combine with other fertilizers to avoid this risk.
-
Environmental Contamination: Improper disposal (e.g., pouring into water bodies) can harm aquatic life. Dispose of waste responsibly to prevent pollution.
-
Animal Toxicity: Monitor animals for behavioral changes, as some regulators may pose toxicity risks. Report abnormalities to relevant authorities.
-
Long-Term Risks: Extensive use may induce plant resistance, reducing effectiveness. Rotate applications or incorporate alternative methods to mitigate resistance.
Brassinolide and gibberellic acid are potent tools for agriculture when used correctly. Prioritize adherence to dosage guidelines, environmental protection, and safety protocols. For specific concerns or guidance, consult professionals or reference technical documentation.
