“Ethylene" is a plant hormone found in rubber, playing a role in root development and participating in latex vessel operation. It stimulates latex production, facilitating a slower coagulation process, and resulting in a more viscous latex flow. Scientists have devised various methods to supplement ethylene into the plant stem based on these properties. The most common method is applying on a splitting mouth (ethephon absorbed by the tree releases ethylene), which is widely used by farmers. In Vietnam, Ethephon goes by several trade names such as Adephone 2.5Paste, Callel 2.5Paste, Forgrow 2.5Paste, Sagolatex 2.5PA..."...
