Sodium o-nitrophenolate can be used as a plant cell activator, which can quickly penetrate into the plant body, promote the flow of cell protoplasm, and accelerate the rooting speed of plants.

The main types of plant root and stem expansion agents include chlorformamide and choline chloride/naphthyl acetic acid.
Choline chloride is a synthetic plant growth regulator that can promote the rapid expansion of underground roots and tubers, improve yield and quality. It can also regulate the photosynthesis of leaves and inhibit photorespiration, thereby promoting the expansion of underground tubers.

Plant growth regulators that promote early maturity of plants mainly include the following types‌:Gibberellic Acid (GA3)‌: Gibberellic Acid is a broad-spectrum plant growth regulator that can promote the growth and development of crops, make them mature early, increase yields, and improve quality. It is suitable for crops such as cotton, tomatoes, fruit trees, potatoes, wheat, soybeans, tobacco, and rice‌.

Plant rooting is one of the important stages of plant growth and is of great significance to the growth, development and reproduction of plants. Therefore, how to promote plant rooting is an important issue in plant cultivation. This article will discuss how to promote plant rooting from the aspects of nutritional conditions, environmental factors, and treatment methods.
