1、Practical applications of brassinosteroids in horticulture—Some field

However, more accurate studies on dosage, mode and time of application, fit brassinosteroid suitability for the plant or cultivar, and association with other phytohormones are needed. The preliminary results regarding the increases of crop yield and antistress effects on several plants are effective at very low doses.

2、Brassinosteroids: Improving Crop Productivity and Abiotic Stress

For this study, C. pepo plants were grown in the pots and when a plant grown for four true leaves, brassinozole, and a brassinosteroid biosynthesis inhibitor was sprayed and flower development was studied. BR-deficient and BR-insensitive mutants show evidence of late flowering phenotype (Li et al. 2010).

The steroid hormones used in agriculture are chemically synthesized. Currently, different brassinosteroid species, including chimeric molecules of brassinosteroids with other biologically active compounds, are used on plants for food, drug, and technical purposes.

Understanding brassinosteroid

Brassinosteroids (BRs) play a crucial role in regulating multiple biological processes in plants, particularly those related to crop productivity and stress tolerance. During their functioning, BRs engage in extensive and intricate interactions with other phytohormones, including auxin, cytokinins, …

Designed Manipulation of the Brassinosteroid Signal to Enhance Crop

Brassinosteroid (BR), a plant steroid hormone, plays crucial role in modulating plant growth and development, which affect crop architecture and yield. However, BR application cannot highly benefit to agricultural production as expectation, because it regulates multiple processes in different tissues and leads to side effect. In addition, accurately modifying BR signal at transcriptional level ...

Brassinosteroid is a plant growth regulator widely used in agricultural production, particularly for promoting crop growth, increasing yields, and improving quality. The methods and frequency of brassinosteroid application vary depending on factors such as crop type, growth stage, climate conditions, and soil status. Below is a detailed guide on general practices and recommended frequencies for different crops, along with practical advice.

I. Crop Types and Growth Stages

1. Cereal Crops (e.g., Wheat, Rice)

• Growth Stages: For wheat, apply during the jointing to heading stages; for rice, apply during tillering to jointing. These periods are critical for nutrient uptake. Brassinosteroid promotes root development, stress resistance, and photosynthetic efficiency.
• Application Method: Use a knapsack or manual sprayer to evenly cover crops. Ensure thorough coverage of leaves (especially veins and stems) for optimal absorption.
• Frequency: 2-3 applications per mu, spaced 7-10 days apart, adjusted for local climate and soil.

2. Cash Crops (e.g., Cotton, Tomato)

• Growth Stages: Apply to cotton before and after flowering, and to tomatoes during flowering and fruiting. This boosts yield and quality.
• Application Method: Use drones or manual sprayers for uniform coverage. Avoid direct spraying on flowers to prevent interference with pollination.
• Frequency: 2-3 applications per mu, spaced 7-10 days apart.

3. Vegetable Crops (e.g., Cucumber, Pepper)

• Growth Stages: Apply to cucumbers before flowering and peppers after flowering to enhance flower bud differentiation and fruit set.
• Application Method: Use knapsack or manual sprayers for full-plant coverage. Avoid spraying directly on flowers.
• Frequency: 2-3 applications per mu, spaced 7-10 days apart.

II. Climate Conditions and Soil Status

1. Temperature and Humidity

• High Temperature/Drought: Increase application frequency and concentration to improve drought resistance and disease resilience.
• Low Temperature/High Humidity: Use brassinosteroid to boost photosynthesis and growth, but avoid over-spraying to prevent fungal diseases.

2. Soil Fertility

• Poor Soils: Higher frequency and concentration may be needed to compensate for nutrient deficiencies.
• Fertile Soils: Use to enhance disease resistance, but reduce concentration to avoid excess nutrient intake.

III. Precautions and Recommendations

1. Select Appropriate Formulations and Concentrations

• Formulation: Choose products suited to local climates (e.g., nitric formulations for dry regions). Ensure quality by selecting reputable brands.
• Concentration: Adjust based on crop type, stage, and weather. Overconcentration may cause phytotoxicity.

2. Follow Proper Application Methods

• Mixing: Dilute brassinosteroid 500-800 times with water as per instructions.
• Coverage: Ensure even spraying across leaves, stems, and soil. Avoid direct contact with flowers.

3. Monitor Effects and Adjust Protocols

• Observe Results: Track crop growth, yield, and quality post-application. Compare pre- and post-treatment metrics.
• Adapt Strategies: Modify frequency, concentration, or timing based on observations. Watch for signs of phytotoxicity (e.g., leaf yellowing, wilting).

Brassinosteroid application requires careful consideration of crop type, growth stage, climate, and soil. Scientifically planned spraying can maximize growth and yields. cautious use is essential to avoid adverse effects. Always prioritize monitoring and timely adjustments for optimal results.
