1、Involvement of brassinosteroid signals in the floral

So far, reports on a connection between BRs and flowering time are limited. This review summarizes recent advances regarding the action of BRs in the transition to flowering.

2、Brassinosteroid action in flowering plants: a Darwinian perspective

These studies led to the discovery of a new class of phytohormones, the brassinosteroids (BRs) that were isolated from rapeseed (Brassica napus) pollen.

3、Effects of Exogenous Brassinolide on Prolonging Flowering Period and

Compared with the control, spraying 0.5 mg/L BR was beneficial to prolong the flowering period of ‘Red Lion’, which was extended by 11 days; it also significantly increased the flower diameter, scape length, and plant height by 63.25, 11.5, and 7.04%, but the number of florets per scape decreased.

4、Can Brassinolide Promote Flower Bud Development? Usage Guidelines

Tomato Flowering Promotion: Spraying brassinolide during the bud stage boosts flower bud formation, accelerating fruiting and improving yield/quality. Pepper Ripening: Applying brassinolide at early flowering or pre-harvest stages enhances fruit maturation, flavor, and marketability.

Effective Use of Brassinolide for Enhanced Flowering in Plants

By understanding its mechanism of action, we can more effectively use BR or other growth regulators to regulate plant flowering and growth, thereby enhancing plant productivity and environmental adaptability, which is of great significance for achieving sustainable agricultural development.

Evaluation of Effect of Brassinolide in Brassica juncea Leaves under

Two foliar sprayings with brassinolide (10 and 20 mg/L) were carried out in both cultivars (RH 725 and RH 749) at two stages—i.e., flower initiation, and 50% flowering—under stress conditions.

Research Progress of Brassinolide in Regulating Plant Growth and

BR significantly affects the reproductive growth of plants, by regulating the flowering time of plants, prolonging the flowering period, and increasing the number of flowers.

How to use brassinolide?

Regardless of the initial flowering period, the flowering period, and the needle period of peanuts, the dwarfing effect of plants can be clearly shown 5 days after spraying.

Practical applications of brassinosteroids in horticulture—Some field

Brassinosteroids (BS) are a class of steroidal plant hormones which are highly stable and environment friendly. They are involved in a wide range of physiological and biochemical responses in plants. Their role in the increase in productivity of agricultural and oil seed crops is well established.

Effect of Spraying with Brassinolide and Boric Acid on Growth and

The experiment was conducted at a nursery of the agricultural research station of the Faculty of Agriculture / University of Kufa during the 2024 growing season to study the effect of spraying with brassinolide and boric acid on the growth and flowering of aster plant.

Brassinolide, also known as rapeseed sterol, is a plant growth regulator widely used in agricultural production. It regulates plant growth and development, promotes flower bud differentiation, and enhances crop yield and quality. whether its use can inhibit flowering remains inconclusive. Here are potential causes and recommendations:

1. Improper Application Methods: Brassinolide must be used correctly, including proper dilution ratios and application timing. Incorrect usage may prevent plants from absorbing the regulator effectively, disrupting flowering. Always follow product instructions precisely.

2. Environmental Factors: Light, temperature, and water significantly impact plant growth. These conditions might alter brassinolide’s effectiveness, leading to abnormal flowering. Ensure plants are grown under optimal environmental conditions when using the regulator.

3. Varietal Sensitivity: Different plant varieties respond variably to brassinolide. Some may thrive, while others resist its effects. Choose a formulation tailored to the target species and monitor plant reactions closely.

4. Pest and Disease Impact: Stress from pests or diseases can hinder growth and disrupt flowering. Before applying brassinolide, inspect plants for signs of infestation or infection and take corrective action.

5. Soil Conditions: Soil nutrient levels and pH affect brassinolide absorption. Poor soil health may reduce its efficacy. Improve soil conditions (e.g., via amendments) to support plant vitality.

6. Plant Physiological State: Plants in dormant phases or with nutrient deficiencies may not respond well to brassinolide. Apply the regulator to healthy, actively growing plants for best results.

7. Growth Stage Timing: Plant sensitivity to brassinolide varies by developmental stage. Adjust application timing to match the most responsive phases of growth.

Whether brassinolide inhibits flowering depends on multiple factors, including application methods, environmental conditions, plant variety, pest/disease presence, soil health, physiological state, and growth stage. For optimal results and minimal risks, carefully evaluate these factors before use. Additionally, prioritize maintaining healthy growing conditions and addressing any issues promptly.
