The Impact of Forchlorfenuron on Fruit Cultivation

Understanding Forchlorfenuron and Its Benefits

Forchlorfenuron, also known by trade names such as Fengbao and Fast Big, is a phenylurea derivative with notable cell division activity. It is a potent plant growth regulator that was first developed in the United States and has since been recognized for its ability to stimulate cell division, differentiation, and expansion. This compound not only promotes the formation of proteins and organs but also bolsters the resistance and anti-aging properties of crops and fruit trees.

Key Functional Roles of Forchlorfenuron:

• Promotion of Fruit Enlargement: Forchlorfenuron has a significant impact on the size of fruits such as grapes, kiwi, and cucumbers, leading to increased crop yields.
• Enhancement of Fruit Set: Application of forchlorfenuron can improve the fruit set of various fruits and vegetables, particularly when applied during or before flowering.
• Induction of Callus Formation: The substance has a higher cell proliferation rate compared to other plant growth regulators.
• Improvement of Fruit Quality: While accelerating crop growth, forchlorfenuron also enhances the quality of agricultural products.
• Induction of Parthenocarpy: Forchlorfenuron can induce the development of seedless fruits in crops like watermelon and bitter gourd.

Specific Applications and Effects on Crops:

• Grapes: Applying 3-8mg/L of forchlorfenuron during the final flowering stage can reduce shattering and improve fruit set. A subsequent application of 5-15mg/L after blossom fall can accelerate fruit enlargement and increase fruit weight.
• Cucumbers: Using 5-20mg/L of forchlorfenuron on blooms or before flowering can promote early fruit development and enhance market value.

Precautions and Best Practices

While forchlorfenuron is highly effective, it requires careful handling to avoid adverse effects such as hollow or deformed fruits and cracking. Users should adhere to recommended concentrations, application timing, and methods. It is crucial to use the solution immediately after mixing and to conduct small-scale trials before widespread application. Additionally, the treatment should target the small melon rather than flowers or stems to prevent deformities.

Important Considerations:

• Concentration and Timing: Adjust the concentration based on temperature conditions and avoid arbitrary increases to prevent negative outcomes.
• Application Method: Evening or morning applications are preferable, and artificial pollination can enhance results.
• Safety Measures: Keep forchlorfenuron away from food, seeds, and feed, and ensure it is out of reach of children and livestock.

Conclusion

Forchlorfenuron is a powerful tool for fruit tree cultivation, capable of significantly boosting fruit size and yield. However, its use must be carefully managed to prevent potential side effects. By following the guidelines and best practices, growers can safely harness the benefits of this plant growth regulator to produce high-quality, pollution-free fruits.
