EBL application enhances plant growth and development under drought stress by acting as signalling compound in different physiological processes. This article discussed potential role of 24-epibrassinolide application and drought tolerance in plants.

3、Effect of 2, 4

The effects of 2, 4-epibrassinolide (EBR) on the growth and flower stalk nutritional quality of flowering Chinese cabbage (Brassica parachinensis Bailey) were studied in order to screen out optimal application concentration and spraying period.

Common brassinolide effects and use precautions

The application methods of Brassinolide are mainly foliar spraying and soil root irrigation. Foliar spraying absorbs quickly and has a rapid effect, which is suitable for situations where rapid nutrition supplementation is needed or to cope with sudden adversity.

The optimum temperature for growth is approximately 18 ̊ C with an average maximum of 24 ̊ C and an average minimum of 4.5 ̊ C. The crop is also generally frost resistant.

Brassinosteroids Application in Ornamental Crops: A Review

At first campesterol (which is the precursor of brassinolide) is converted to campestenol, which is further converted to castasterone through either early or late C-6 pathway. In the final step, castasterone is oxidized to produce brassinolide [10].

Brassinolide (also known as油菜素内酯, brassinolide) is a plant growth regulator that promotes growth, enhances stress resistance, and improves crop quality. In agricultural production, proper use of brassinolide can effectively increase crop yields and quality. its effectiveness depends on timing and application methods. Below are the optimal periods for applying brassinolide to cabbage:

1. Growth Stages of Cabbage

Cabbage development includes four stages: seedling stage, rosette stage, heading stage, and maturity stage. Brassinolide requirements vary by stage:

• Seedling and Rosette Stages: Critical periods for growth. Applying brassinolide here promotes plant growth, disease resistance, and yield potential.
• Heading and Maturity Stages: Cabbage enters senescence. Brassinolide may have limited effects during these phases. Recommendation: Apply brassinolide primarily during the early growth stages (seedling and rosette stages).

2. Disease Presence

If cabbage suffers from diseases (e.g., virus, downy mildew), brassinolide can inhibit pathogen development. Priority application is advised when diseases emerge to mitigate damage.

3. Climatic Conditions

Cabbage growth is sensitive to weather. Under stress conditions (e.g., high temperatures, drought):

• Brassinolide stimulates growth and improves yield/quality.
• Adjustment: Increase dosage or frequency under adverse climates.

4. Soil Fertility

In low-fertility soils, brassinolide enhances root development and nutrient absorption, boosting yield and quality. Adjustment: Increase application in nutrient-poor soils.

5. Fertilization Practices

Ensure adequate fertilization before applying brassinolide. Proper nutrient supply optimizes its absorption and effectiveness.

6. Application Methods

Brassinolide can be applied via:

• Spraying (foliar or whole-plant),
• Drip irrigation,
• Foliar spraying. Choose the method based on specific conditions to maximize results.

7. Concentration Control

Higher concentrations may enhance effects but risk phytotoxicity. Adjust concentrations according to crop response and guidelines.

8. Timing of Application

Earlier application (during growth phases) yields better results. Early use supports growth promotion more effectively.

The optimal time for brassinolide application in cabbage is during the early growth stages, particularly the seedling and rosette periods. Tailor application timing and methods to specific conditions (e.g., disease, climate, soil) to maximize benefits. Avoid overuse to prevent adverse effects.
