Plant growth regulators have been developed in recent years, and there are many varieties. The various plant growth regulators on the market make us dazzled. Today, the pesticide network is simple and simple to classify plant growth regulators:
It has been found that substances regulating plant growth and development include auxin, gibberellin, ethylene, cytokinin, abscisic acid, brassinolide, salicylic acid, jasmonic acid and polyamines, chlormequat, and anti-fallin. Plant growth inhibitors and accelerators, etc., and are used as plant growth regulators in agricultural production, mainly in the first six categories.
The most common plant growth regulators are available amines (DA-6), chlorpyrifos, sodium nitrophenolate, fruit treasure, brassinolide, gibberellin.
There are the following types according to their uses: Prolong storage organ dormancy: chlorophyll, sodium naphthalene acetate, methyl naphthalene acetate. Breaking dormancy promotes germination: gibberellin, kinetin, thiourea, chlorohydrin, hydrogen peroxide. Promote stem and leaf growth: gibberellin, 6-benzylaminopurine, brassinolide, triacontanol. Promote rooting: å²å“šbutyric acid, naphthaleneacetic acid, 2,4-D, longer than a long time, paclobutrazol, ethephon, 6-benzylaminopurine. Inhibition of stem and leaf bud growth: paclobutrazol, doconazole, chlormequat, Bijiu, Pixar, triiodobenzoic acid, chlorophyll, and powder embroidery. Promote flower bud formation: ethephon, longer than 6-benzylaminopurine, naphthaleneacetic acid, 2,4-D, chlormequat. Inhibition of flower bud formation: gibberellin, modulating phosphine. Thinning and thinning: naphthaleneacetic acid, carbaryl, ethephon, gibberellic acid, benzoic acid ester, 6-benzylaminopurine. Preserved fruit: 2,4-D, naphthaleneacetic acid, anti-fallin, gibberellin, chlormequat, longer than 6-benzylaminopurine. Extend flowering period: paclobutrazol, chlormequat, ethephon, longer than. Inducing the production of female flowers: ethephon, naphthaleneacetic acid, indole acetic acid, chlormequat. Induction of male flowers: gibberellin cut flowers preservation: ammonia oxyethyl vinyl glycine, ammonia oxy acetic acid, silver nitrate, silver thiosulfate. Form seedless fruits: gibberellin, 2,4-D, anti-fallin, naphthaleneacetic acid, 6-benzylaminopurine. Promote fruit ripening: Ethephon, longer than. Delay fruit ripening: 2,4-D, gibberellin, longer than, kinetin, naphthaleneacetic acid, 6-benzylaminopurine. Delaying aging: 6-benzylaminopurine, gibberellin, 2,4-D, kinetin. Increase the amino acid content: paclobutrazol, anti-fallin, and cooked ester. Increase protein content: anti-fallin, simazine, atrazine, naphthaleneacetic acid. Increase sugar content: Glyphosate, phosphine, Pixar. Promote fruit coloration: longer than long, cooked ester, paclobutrazol. Increase fat content: naphthaleneacetic acid, chlorophyll, toxin. Improve stress resistance: abscisic acid, paclobutrazol, longer than a short period of time.
