Regulators that promote soybean seed germination and regulate seedling growth
Gibberellic acid GA3
In high northern latitudes, low temperature (such as 10~15℃) often prolongs the germination process of spring-sown soybeans, delays germination, and reduces the germination rate. The lower the temperature, the lower the germination rate.At the same time, low temperature will increase the chance of infection of soybean sprouts, reduce the viability of seedlings, and cause uneven populations.Soaking seeds with 3.5 mg/L gibberellic acid solution for 2 hours can effectively speed up the initial germination of spring soybeans at 10-15 ℃, significantly accelerate the growth rate of young roots, and increase the fresh and dry weights of young roots.
Sodium nitrate
Soaking seeds with sodium nitrophenolate 10 mg/L or 5-nitroguaiacol sodium 5 mg/L for 12 h can increase the bud weight, germination potential, germination rate and seed vigor of soybean.
Diethyl aminoethyl hexanoate
Soaking seeds with 160-320 mg/L diethyl aminoethyl hexanoate for 2 hours can improve the stress resistance of soybean seedling stage and promote the activity of protective enzymes under drought stress;At the seedling stage, 10 mg/L ethyl hexanoate combined with pyraclostrobin was sprayed to increase the leaf length and leaf width of soybean seedlings, increase the leaf area, thus increase the photosynthesis of the plant and promote the nutrient in the plant. Accumulation, and ultimately improve the overall metabolic capacity of plants, alleviate the damage of high concentrations of pyraclostrobin to soybean seedlings, and improve soybean stress resistance.
Kinetin
At low temperature, soaking seeds with 1 mg/L kinetin solution for 2 h can effectively accelerate the initial germination rate of spring soybeans at 10-15 °C, significantly accelerate the growth rate of young roots, and increase the fresh and dry weights of young roots.The promotion effect at 10°C is better than that at 15°C, and at 25°C, there is no obvious promotion effect.
Brassinolide
Brassinolide can increase the activity of nitrate reductase in soybean seedlings, increase the absorption and transformation of nitrate fertilizers, increase plant height and material accumulation, and improve the resistance of crops to adverse environments.On this basis, the cotyledons were sprayed with 0.01 mg/L medicinal solution after soybean emergence, and the plant height increased by 10%-15% and the fresh root weight by 40%-60% after 6 days.
Triacontanol
Seed soaking with 0.05mg/L triacontanol for 6h or seed dressing treatment with 0.5mg/kg (seed). Both can improve the germination rate and germination potential, increase the 3-kernel pod, reduce the single-kernel pod, and increase the number of beans per pod.
Chitosan
The seeds were coated with 125-165 mg of chitosan per kilogram or soaked with 1.2% liquid for 1 h. It can improve the germination rate of seeds and improve the vigor of seeds.
