Forchlorfenuron丨CAS 68157-60-8

Forchlorfenuron丨CAS 68157-60-8, is a synthetic cytokinin-like plant growth regulator (PGR) widely used in agriculture and horticulture to promote cell division, fruit development, and increase crop yields. Chemically, it is known as N-(2-chloro-4-pyridyl)-N'-phenylurea, and functions similarly to natural cytokinins by promoting cytokinesis, cell enlargement, and delay of senescence. Forchlorfenuron has been adopted globally, particularly in high-value crops such as grapes, kiwifruit, melons, and citrus.

A. Fruit Size Enlargement

One of the most prominent uses of forchlorfenuron is to increase the size and weight of fruits, especially in crops like kiwifruit, grapes, apples, and melons.

By enhancing cell division and elongation, CPPU-treated fruits develop with greater volume and improved market value.

B. Yield Improvement

CPPU significantly contributes to increased fruit set and final yield when applied at critical reproductive stages.

In crops like citrus, mangoes, and bananas, application improves both fruit retention and size, resulting in higher total productivity per plant.

C. Delay of Senescence

Forchlorfenuron丨CAS 68157-60-8 delays natural leaf aging and fruit softening, extending the photosynthetic activity of leaves and the post-harvest life of produce.

Increases storage potential of crops by retaining firmness, color, and texture longer, especially in table grapes, strawberries, and peaches.

D. Flower and Fruit Thinning

When applied at specific concentrations or stages, CPPU can also assist in thinning excessive fruit load by modulating hormonal balance and abscission.

This controlled thinning helps achieve uniform fruit size and improved quality by reducing intra-plant competition.

E. Seedless or Parthenocarpic Fruit Production

Forchlorfenuron can induce parthenocarpy, the development of fruit without fertilization, especially useful in cucumber, melon, and some berry crops.

Ideal for producing seedless fruits, which are preferred in fresh markets and export-oriented supply chains.

F. Ornamental and Floriculture Use

In ornamental plants, it is used to enhance shoot proliferation, delay wilting, and prolong flower longevity.

Helps improve aesthetic appeal and shelf life of cut flowers during storage and transportation.

A. Promotes Vigorous Fruit Development

By stimulating mitosis (cell division) and enhancing cytoplasmic expansion, CPPU-treated fruits grow larger and more uniform in size.

In crops like grapes and kiwifruit, this results in significantly increased commercial quality and value.

B. Improves Crop Uniformity and Quality

Ensures more even ripening and fruit appearance, which is critical in mechanized harvesting and export grading.

Enhances characteristics such as skin brightness, firmness, and sugar content, depending on application timing and dosage.

C. Extends Shelf Life and Marketability

Delays fruit softening and aging, extending the harvest window and reducing post-harvest losses.

Enables longer-distance shipping and better adaptability to modern supply chains.

D. Enhances Stress Tolerance

CPPU has been shown to help plants withstand abiotic stresses, including drought, heat, and low light, by prolonging leaf functionality and improving water retention.

Acts synergistically with other hormones like auxins and gibberellins to balance plant growth under fluctuating conditions.

E. Versatile Across Multiple Crops

Effective in a wide range of fruit, vegetable, and ornamental plants, with adaptable application strategies including foliar sprays, trunk injections, or dipping.

Compatible with integrated crop management systems.

Forchlorfenuron丨CAS 68157-60-8 is a powerful, synthetic cytokinin-like plant growth regulator that promotes fruit development, size enlargement, delayed senescence, and enhanced crop yield. With versatile applications across many crops, it has become an essential tool in commercial horticulture, orchard management, and floriculture. When used with care and precision, forchlorfenuron contributes significantly to crop quality, marketability, and economic value, making it a vital component of modern, high-efficiency agriculture.
