A review on exploring the efficiency of plant hormones on fruitfulness

Phytohormones promote growth in the vegetative phase, flowering and fruit development. A novel class of PGR comprises brassinosteroids (BRs) and polyamines (PAs). In fruit crops, fruit drop at the maturity stage is controlled by the external application of BRs and PAs.

Brassinosteroid is a plant growth regulator primarily used to promote plant growth and development, enhance crop yield, and improve quality. In watermelon production, brassinosteroid can effectively retain flowers and fruits, boosting both quality and yield. Below is a detailed guide on its application methods, dosages, and precautions:

I. Application Methods

1. Foliar Spraying

   • Dilute brassinosteroid solution to the appropriate concentration and evenly spray it over the watermelon leaves. Avoid direct contact with the fruits to prevent adverse effects.
   • Timing: Conduct spraying during the morning or evening to avoid high-temperature periods.

2. Soil Application

   • Dissolve brassinosteroid in water and apply it around the root zone of watermelon plants. Ensure the solution does not directly touch the roots to avoid damage.
   • Timing: Apply during the morning or evening to avoid heat stress.

3. Under-Leaf Spraying

   • Spray the solution onto the underside of leaves to promote fruit expansion and maturation. Avoid spraying directly onto fruits.
   • Timing: Perform during cool periods (morning or evening).

II. Dosage Guidelines

1. Foliar Spraying

   • Adjust concentration based on plant size and growth stage.
   • Dosage: 50–100 milliliters (mL) of solution per mu (≈0.067 hectares).

2. Soil Application

   • Customize concentration according to plant needs.
   • Dosage: 1–2 kilograms (kg) of solution per mu.

3. Under-Leaf Spraying

   • Modify concentration based on growth stage.
   • Dosage: 50–100 mL of solution per mu.

III. Precautions

1. Apply in Minute Quantities, Multiple Times: Avoid overuse to prevent phytotoxicity.
2. Tailor to Varieties and Stages: Adjust application methods and dosages for different watermelon varieties and growth phases.
3. Integrated Practices: Combine with balanced fertilization, pest control, and other agronomic practices for optimal results.
4. Regulatory Compliance: Adhere to national standards and safety guidelines for agricultural chemicals.

Brassinosteroid is a potent tool for improving watermelon flower and fruit retention. Proper application—following dosage guidelines, timing protocols, and regulatory standards—enhances yield and quality while ensuring safety. When used strategically alongside other farming practices, it contributes significantly to agricultural productivity.

Note: "Mu" (亩) is a traditional Chinese unit of area (≈666.7 square meters). For international contexts, dosages may be converted to metric or imperial units (e.g., liters/hectare or ounces/acre) as needed.
