Product_introduction
Paclobutrazol mainly affects plant growth and development by inhibiting the biosynthesis of gibberellins in plants. It acts on a key enzyme in the synthesis of gibberellins, hindering the conversion of kaempferol to kaempferol, reducing the content of gibberellins in plants, and thereby inhibiting the elongation and division of plant cells, achieving the effect of controlling plant growth and dwarfing plants. Meanwhile, paclobutrazol can also increase the activity of indole-3-acetic acid oxidase in plants, reduce the level of auxin, and further inhibit plant growth.
Physiological effects
Dwarf plants: can effectively control the longitudinal growth of plants, shorten the internodes, make the stems thick and sturdy, compact the plant shape, and enhance the plant's ability to resist lodging.
Promote branching: Promote lateral bud germination and lateral branch growth, increase the number of branches in plants, make them more lush, facilitate the formation of a good plant shape, and improve crop yield.
Improving stress resistance: It can enhance the adaptability of plants to adverse conditions such as drought, low temperature, and salinity. It can regulate the physiological metabolism of plants to maintain a good growth state under adversity and reduce the damage of adversity to plants.
Adjusting flowering period: In some flowering plants, paclobutrazol can regulate flowering period, making flowers more concentrated and increasing their ornamental value.
Application scope
Agricultural crops: widely used in grain crops such as rice, wheat and corn, and oil crops such as rape, soybean and peanut.
Fruit trees: In the cultivation of apple, pear, peach, citrus and other fruit trees, paclobutrazol can control new shoot growth, promote flower bud differentiation, increase fruit setting rate, and improve fruit quality
Vegetables: For some vegetables that are prone to overgrowth, such as tomatoes, cucumbers, peppers, etc., paclobutrazol can inhibit their nutritional growth, promote reproductive growth, make the plants dwarf and compact, improve light energy utilization efficiency, and increase early yield. In flower production, it can be used to control plant shape, make flowers look beautiful, and increase commodity value.
