Seed soaking solution and method for improving germination rate of aged peanut seeds

Abstract

The invention relates to a seed soaking solution for improving a germination rate of aged peanut seeds. The seed soaking solution comprises 100 to 300 mg / L of gibberellin GA3, 0.1 to 0.3 mg / L of brassinolide, 0.1 to 0.3 mg / L of ethylene, 0.1 to 0.3 mg / L of cytokinin 6-BA and 0.2 to 0.4 mg / L of auxin IAA. The invention also provides a method for improving a germination rate of aged peanut seeds. The method comprises S1, pretreatment: airing aged peanut seeds, S2, seed soaking solution preparation from 100 to 300 mg / L of gibberellin GA3, 0.1 to 0.3 mg / L of brassinolide, 0.1 to 0.3 mg / L of ethylene, 0.1 to 0.3 mg / L of cytokinin 6-BA and 0.2 to 0.4 mg / L of auxin IAA, and S3, seed soaking: soaking peanut seeds in warm water for 0.5h, soaking the peanut seeds in the seed soaking solution at thenormal temperature and taking out the peanut seeds for sowing.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a seed soaking solution and a method for increasing the germination rate of aging peanut seeds. Background technique [0002] Peanut (Arachis hypogaea L.) is one of the four major oil crops in the world, and it is also an important oil crop and economic crop in my country. my country's total peanut production, consumption and export volume rank first in the world for a long time, so peanuts occupy a pivotal position in my country's agricultural economy. [0003] Peanut seeds are prone to aging during storage at room temperature, resulting in reduced seed vigor and reduced germination rate. Therefore, improving the germination rate of peanut seeds, accelerating seed germination, and promoting seed emergence have become the key links to ensure high and stable peanut yields. At present, there are few studies on how to improve the germination rate of peanut seeds, and farmers g...

AI Technical Summary

Problems solved by technology

Although the method of soaking seeds in warm soup is simple, fast and low in cost, there are still many problems, including low seed germination rate, slow seedling emergence, irregular seedling emergence, and serious phenomenon of large and small seedlings.

Recently, some studies have used gibberellin solution to soak peanut seeds for 8 hours to accelerate germination, which can increase the germination rate by 5%-8%, but the overall effect on the germination rate is not obvious, especially for aging peanut seeds with a very low germination rate. , it is not meaningful to only increase the germination rate by 5%-8%
