Fruit trees are a type of plant that people often come into contact with in daily life, and the color of the fruit is a phenomenon that is naturally formed during the growth of fruit trees. However, external environmental factors have a great impact on the color of the fruit, and may also have adverse effects. At this time, spraying colorants has become one of the effective countermeasures to improve the color of the fruit.

There are many kinds of plant growth regulators on the market today that can promote fruit coloring, among which the more common colorants such as brassinolide, choline chloride, Ethephon, Triacontanol, etc. are available for us to choose.

Brassinolide was originally found in rapeseed pollen, which can promote endogenous growth of plants, increase yield and commodity added value. The method of use is to spray brassinolide during the expansion period or color change period of the fruit to promote fruit coloring and increase sugar content.

Choline chloride can make the fruit larger, sweeter, and promote coloring or color change. Spraying fruit trees during the color change period of the fruit can also improve the appearance of the fruit.

Ethephon is a plant growth regulator that has the effects of ripening, coloring, increasing the number of female flowers, sweetening, and increasing yield. During the fruit color change period, 400 times diluted 40% Ethephon solution can be used for whole plant spraying to promote fruit color change and early maturity.

Triacontanol can promote the accumulation of dry matter in fruit trees and increase fruit color change and yield.
