Abstract

The invention discloses a method for improving the stress resistance of soybean seeds during germination. The method comprises intercropping corn and soybeans according to a line ratio of 1: 1, after the soybeans are mature, harvesting soybean seeds, carrying out natural air-drying, selecting the soybean seeds having even sizes, pump shapes and no diseases and worm damage for next use, planting the treated soybean seeds in soil, carrying out culture, regularly and quantificationally spraying an appropriate amount of tap water to the soil during germination and carrying out germination for 12-48h. Through use of the method, high temperature resistance, salt stress resistance, drought stress resistance and ABA stress resistance are improved in intercropped soybean seed germination. In the intercropped soybean seed germination, two key genes of GmABI4 and GmABI5 for abscisic acid signal transduction have a transcriptional level lower than that of sole cropping and thus the ABA signal is weakened in the intercropped soybean seed germination and the seeds have a stronger germination capacity under abiotic stress.

Description

technical field [0001] The invention belongs to the field of soybean cultivation, and in particular relates to a method for improving stress resistance of soybean seeds during germination. Background technique [0002] In recent years, with global climate change, soil degradation and improper management of irrigation measures, abiotic stresses (high temperature, drought, salinity, etc.) have become increasingly serious, limiting crop growth and development, and ultimately leading to a decline in yield. Soybean is not only an important food crop and oil crop, but also an important industrial raw material, which plays an important role in production and life. Abiotic stress can significantly reduce the germination rate of soybean seeds, inhibit the growth of seedlings, and lead to a severe reduction in soybean yield. Therefore, enhancing soybean stress resistance is of great significance for increasing soybean yield and improving quality. [0003] Under the corn / soybean inte...
