Plant growth regulators are mainly divided into the following categories:
Hormone: including plant growth hormone, gibberellin, cytokinin, etc., which can regulate various stages of plant growth and development.
Antibiotics: such as carbendazim, streptomycin, etc., have antibacterial and antiviral effects, and can protect plants from diseases.
Stress resistance regulators: such as proline, polysaccharides, etc., can improve the resistance of plants to adverse environments and enhance the stress resistance of plants.
Biologically active substances: such as natural organic acids, amino acids, etc., can promote plant growth and development, and improve plant yield and quality.
Nutrient regulators: such as trace element fertilizers, organic fertilizers, etc., can regulate the nutritional balance of plants and provide the nutrients needed by plants.
Biological pesticides: such as insecticides, fungicides, etc., can control plant diseases and pests and protect the growth and development of plants.
Bioactivators: such as plant bioactive substances, microbial preparations, etc., can activate the physiological metabolism of plants and promote plant growth and development.
Antioxidants: such as vitamin C, vitamin E, etc., can inhibit oxidation reactions, reduce the production of free radicals, and protect plant cells from oxidative damage.
Growth regulator complexes: Combining multiple growth regulators to form a complex can comprehensively play the role of multiple regulators and improve the growth effect of plants.
Biological inducers: such as plant inducers, microbial inducers, etc., can induce plants to produce specific defense reactions and enhance the disease resistance of plants.
The above are some common types of plant growth regulators, which have important applications in agricultural production and horticultural planting.
