Thidiazuron Promotes Cell Division and Tissue Differentiation
Thidiazuron, a plant growth regulator, primarily increases germination rate by regulating endogenous hormone levels. Its mechanisms of action include promoting cell division, breaking dormancy, and optimizing hormone balance. Specifically, they are as follows:
Thidiazuron Promotes Cell Division and Tissue Differentiation
Thidiazuron strongly promotes cell division and expansion, increasing cell number. During the cotton seedling stage, it accelerates stem elongation and leaf growth, improving photosynthetic efficiency and resulting in thicker, greener, and more lush leaves.
Thidiazuron's Dormancy-Breaking Mechanism
This substance breaks seed dormancy, promoting rapid germination and significantly improving seedling emergence and uniformity.
Thidiazuron Regulates Hormone Balance
Thidiazuron regulates hormone levels by inhibiting ethylene production and delaying chlorophyll degradation, creating a favorable environment for germination. For example, its application to crops like grapes and citrus can reduce preharvest fruit drop and increase marketable fruit yield. For vegetables like tomatoes and cucumbers, it promotes flower bud differentiation and increases the number of fruits per plant.
