The term "melon melon fruit" refers to a type of melon that stops growing early and reaches the size of a walnut without further expansion. These fruits are significantly smaller than normal melons of the same variety, with a hard skin, delayed maturity, and no commercial value. Several factors contribute to this issue: low-position fruit setting, where the melons are prone to falling off; limited fruit growth due to insufficient water or nutrients; poor nutrient allocation caused by weak plant growth or excessive vegetative growth; and prolonged bad weather after fruit set, which disrupts nutrient transport and causes the rind to harden prematurely. To prevent the formation of these unproductive melons, two key strategies should be prioritized. First, selecting the right position for fruit setting is crucial. Melons that set in lower positions tend to be small and misshapen, while those that set in higher positions may also be small, have thin flesh, and low sugar content. Proper positioning ensures better fruit quality and uniform development. Second, managing water and fertilizer effectively is essential. After the fruit sets, the cells begin to divide and expand, requiring a significant amount of water and nutrients. When the melon reaches the size of a walnut, it's time to water deeply and apply fertilizer. A recommended dose is 20-30 kg of potassium fertilizer per mu (approximately 667 square meters). If watering is inadequate at this stage, cell division slows down, leading to smaller fruits and potential stalling in growth. Timely and sufficient irrigation and fertilization are therefore vital to ensure healthy development and high-quality produce.

API

what is API?

High-purity plant monomer refers to one or more single chemical components with specific biological activity or pharmacological effects extracted from plants, and its purity is usually high, meaning that the content of the component in the extract reaches a certain percentage, and the content of other impurities or irrelevant components is low.

These plant monomers are usually secondary metabolites of plants, such as flavonoids (flavonoids), alkaloids (alkaloids), terpenoids (terpenoids), phenolics (phenolics), etc., which play a variety of physiological functions in plants such as defense, signal transduction, and antioxidant. Due to their pharmacological activity, high-purity plant monomers are often used in pharmaceuticals, health products, cosmetics and other biotechnology products.

For example, Naringenin is a high-purity plant monomer extracted from citrus plants with antioxidant and anti-inflammatory activities; Corosolic acid is a high-purity active monomer extracted from loquat leaves, which is considered to be effective in treating type 2 diabetes and obesity.

Extraction and preparation of high-purity plant monomers usually require a complex separation and purification process, including extraction, column chromatography, crystallization, recrystallization and other steps to ensure the purity and activity of the final product. These processes may be required by specialized biotechnology companies.
