Uniconazole is a triazole plant growth regulator that primarily works by inhibiting gibberellin synthesis in plants.
1. Uniconazole not only inhibits stem elongation, resulting in compact plants with dark green leaves, but also enhances root vitality, improving the crop's resistance to drought, cold, and pests.
2. Promotes Germination: Uniconazole can promote seed germination through soaking. For example, in rice cultivation, soaking seeds in a 20-50 mg/L Uniconazole solution for 24-48 hours can promote tillering, dwarf the plant, and thus increase yield. Furthermore, Uniconazole can promote lateral bud sprouting, making the plant more compact.
3. Promotes Root Development: By inhibiting gibberellin synthesis, Uniconazole enhances root vitality and promotes root development. Its mechanism of action is similar to paclobutrazol; it is an inhibitor of gibberellin biosynthesis. Its main physiological effects include inhibiting cell elongation, shortening internodes, promoting tillering, inhibiting plant height, altering the distribution direction of photosynthetic products, and promoting flower bud differentiation and fruit growth. Uniconazole can be absorbed through seeds, roots, buds, and leaves, and can be transported between organs.
