How Forchlorfenuron (CPPU) Enhances Fruit Size, Yield, and Quality

Introduction

Forchlorfenuron (CPPU) is a widely used plant growth regulator that promotes cell division and enlargement, making it essential for improving fruit size, yield, and overall quality. Commonly applied in horticulture and agriculture, CPPU is especially beneficial for crops like grapes, kiwifruit, and melons. Its ability to enhance fruit development without affecting plant health makes it a valuable tool for commercial farming.

What is Forchlorfenuron (CPPU)?

Forchlorfenuron (CPPU) is a synthetic cytokinin that stimulates plant cell division and expansion. By increasing fruit size and delaying senescence, it helps crops achieve higher commercial value. Additionally, CPPU can improve fruit firmness, extend shelf life, and enhance resistance to environmental stress.

Key Features of CPPU

• Promotes Cell Division: Encourages rapid fruit enlargement.

• Enhances Yield: Increases the number and size of marketable fruits.

• Delays Aging: Extends the harvest window and shelf life.

• Improves Fruit Quality: Enhances texture, sweetness, and appearance.

Applications of CPPU

CPPU is widely used in the cultivation of various crops, including:

• Grapes: Increases berry size and cluster weight.

• Kiwifruit: Enhances fruit expansion and uniformity.

• Melons & Cucumbers: Boosts fruit development and improves shape.

• Apples & Pears: Reduces premature fruit drop and enhances firmness.

Specifications

• Chemical Name: Forchlorfenuron (CPPU)

• Appearance: White crystalline powder

• Solubility: Soluble in water and organic solvents

• Purity: Typically ≥98%

• Recommended Dosage: 5–20 mg/L, depending on crop type and growth stage

Benefits and Limitations

Benefits:

✔ Increases fruit size without affecting natural taste.
✔ Enhances plant resistance to environmental stress.
✔ Compatible with other agricultural treatments for integrated farming.

Limitations:

✖ Overuse may cause excessive fruit growth, leading to quality issues.
✖ Requires proper application timing to avoid negative effects on fruit shape.

FAQs

1. How does CPPU improve fruit growth?
   CPPU promotes cell division and elongation, leading to larger, more uniform fruits.

2. Can CPPU be used with other plant growth regulators?
   Yes, CPPU is often combined with gibberellins or auxins to enhance fruit development.

3. Is CPPU safe for organic farming?
   No, CPPU is a synthetic growth regulator and is not approved for organic agriculture.

4. How is CPPU applied?
   It is typically applied as a foliar spray at concentrations of 5–20 mg/L during fruit development stages.
