Thidiazuron, a urea-based highly active cytokinin, exhibits a strong cell division promoting effect in a low concentration environment. It can not only stimulate photosynthesis, but also efficiently transport photosynthetic products to the fruit. This characteristic makes thidiazuron widely used in agriculture, such as promoting fruit setting, fruit enlargement, keeping leaves green, delaying leaf aging, and even inducing callus differentiation and budding. In a high concentration state, thidiazuron turns into a cotton defoliant. After being absorbed by the leaves of cotton plants, it can promote the natural separation between the petiole and the stem, thereby achieving leaf fall, providing convenience for mechanical harvesting of cotton, and advancing the cotton harvest time by about 10 days, thereby improving the quality grade of cotton.
The role of Thidiazuron
(1) Promoting fruit expansion
Thidiazuron has a strong promoting effect on cell division and fruit enlargement. It is beneficial to organ damage, growth and enhanced growth, so it plays an important role in fruit expansion.
(2) Nutrient accumulation
Thidiazuron can slow down the aging of plants, keep them green, accelerate the synthesis of chlorophyll, thereby improving photosynthesis and changing the color of leaves from dark to dark, so it is of great significance for nutrient accumulation.
(3) Quality improvement and quantity increase
Thidiazuron can stimulate ovary expansion, increase fruit setting rate, promote protein synthesis, and increase the sugar content in fruits.
