Characteristics and mechanism of Trinexapac-ethyl

I. Characteristics of Trinexapac-ethyl
Trinexapac-ethyl belongs to the cyclohexanedione plant growth regulator, a gibberellins biosynthesis inhibitor, which controls the vigorous growth of plants by reducing the content of gibberellins. Trinexapac-ethyl can be quickly absorbed and conducted by plant stems and leaves, and plays an anti-lodging role by reducing plant height, increasing stem strength, promoting the increase of secondary roots, and developing a well-developed root system.

Trinexapac-ethyl is a plant growth regulator with significant anti-lodging effects. Its molecular structure is stable, easily absorbed by plants, and safe and harmless to the environment and human body. The main function of Trinexapac-ethyl is to regulate the growth process of plants, enhance the toughness and elasticity of stems, and thus improve the lodging resistance of crops. It can be used at most once per crop season.

II. Mechanism of action of Trinexapac-ethyl
The mechanism of action of Trinexapac-ethyl in plants is mainly achieved by affecting the balance of endogenous hormones in plants. Specifically, trinexapac-ethyl can promote the synthesis and distribution of auxin in plants, thicken the cell walls of stems, and make the connections between cells tighter, thereby improving the mechanical strength of stems. At the same time, trinexapac-ethyl can also regulate the photosynthesis and transpiration of plants, making plants stronger during growth and improving their resistance to lodging.
