Promotes wheat seed germination and regulates seedling growth
Application of regulators to promote wheat seed germination and regulate seedling growth
Triacontanol
Soaking seeds with 0.2～0.5mg/L triacontanol for 4～12h can improve the germination vigor of wheat. The soaking time is proportional to the effect of improving germination vigor. Meanwhile, the seed soaking with triacontanol can also improve the growth rate of wheat seedlings in the field.
Sodium Nitrophenolate
Before sowing the wheat seeds, soak the seeds with sodium nitrophenolate at 6-12mg/L for 12 hours, and then air them to half dry before sowing, which can break the seed dormancy, promote germination and rooting, and make the shoots thick and strong.
Chitosan
Coating with 125-165mg/kg (seed) or soaking seeds with 0.1%-0.2% liquid for 24h can activate protease, promote seed germination and seedling growth, improve seedling quality and enhance plant resistance.
Fulvic acid
Seed soaking with 1.67% fulvic acid solution for 30min has the effect of improving the germination rate of wheat and promoting the growth of wheat seedling stage. Compared with the control, the germination rate increased by about 4.87% after 24h. Irrigation of wheat with 0.2% fulvic acid in the field can significantly increase the chlorophyll content of wheat in the field at seedling and greening stages.
Gibberellic acid
The wheat seeds were soaked with 10 mg/L gibberellic acid for 24 hours, rinsed with distilled water 3 times, spread out on filter paper, and then placed in a petri dish for observation. The results showed that the germination index increased by 20.4% and the germination rate increased after soaking. 11.2%, germination potential increased by 21.0%
Naphthalene Acetic Acid (Sodium)
Wheat was cultured with 10 mg/L, 1 mg/L, 0.1 mg/L, 0.01 mg/L, 0.001 mg/L, 0.0001 mg/L, 0.000 01 mg/L naphthalene acetic acid (sodium) solution, and water culture was used as control. After 4 days, the wheat sprouts, root length, chlorophyll content and root activity were measured. The results showed that naphthalene acetic acid (sodium) exhibited low concentration promoting and high concentration inhibiting effects on the growth of wheat roots and shoots. Roots are more sensitive to naphthalene acetic acid (sodium), when the concentration is 0-0.00001 mg/L, 0.00001 mg/L can significantly promote the growth of roots, the average root length is 4.83 cm; the concentration of naphthalene acetic acid (sodium) is 0-0.1 mg /L treatment group had longer buds than the control group, and the effect of 0.0001mg/L treatment was the most obvious. Appropriate concentration of naphthalene acetic acid (sodium) has different degrees of promoting effect on the growth of wheat roots and shoots, and wheat roots are more sensitive to naphthalene acetic acid (sodium) than shoots.
6-BA
Soaking seeds with 15～20mg/L6-BA for 24h, or spraying 2.5～25mg/L liquid on the surface of wheat at 2 leaves and 1 heart stage can improve the germination rate and germination potential, and can improve the ability of seedlings to resist low temperature and drought , and can alleviate the damage of heavy metal stress on seedlings, but its effect varies with wheat varieties.
