Prohexadione calcium is a plant growth regulator that effectively controls the vegetative growth of crops such as rapeseed by inhibiting the synthesis of gibberellins in plants, thereby enhancing lodging resistance and promoting increased yield.
Main effects of Prohexadione calcium:
1. Controlling excessive growth and enhancing lodging resistance: Prohexadione calcium can significantly shorten the internode length of rapeseed stems, making the stems thicker and stronger, reducing plant height, and decreasing the risk of lodging caused by wind and rain.
2. Promoting reproductive growth and increasing yield: While inhibiting excessive stem and leaf growth, Prohexadione calcium can promote flower bud differentiation, increase fruit setting rate, and promote pod development and seed filling, thereby increasing yield per unit area.
3. Improving plant health: This agent can increase chlorophyll content, making the leaves greener and thicker, and enhancing photosynthetic efficiency; at the same time, it promotes root development and improves nutrient absorption capacity, contributing to healthy plant growth.
4. Enhancing stress resistance: Prohexadione calcium can improve the tolerance of rapeseed to abiotic stresses such as drought and low temperature, and to a certain extent reduce the impact of diseases.
