Abstract

The invention discloses a method for improving the germination of soybean seed under NaCl stress. The method comprises the following steps: picking soybean seeds, which have been dried in the air naturally, have a uniform size, are plump, and do not have any insect or disease, saving the soybean seeds for later use; disinfecting the surface of soybean seeds by a pasteurization solution, soaking soybean seeds in a disinfection solution, then washing soybean seeds by sterilized distilled water for four times; processing soybean seeds for 12 to 24 hours by a fluridone solution at a constant temperature in the absence of light; planting the processed soybean seeds in soil, wherein the culture temperature is 20 to 25 DEG C; and during the germination period, spraying a proper amount of tap water, wherein the water quantity and spraying time are fixed, and after 2 to 10d, soybean seeds germinate. The fluridone solution (0.05-0.15 [mu]mol/L) can prominently increase the germination of soybean seeds under NaCl stress and improve the agriculture production efficiency in a saline-alkali area.

Description

technical field [0001] The invention belongs to the field of agricultural application technology, and in particular relates to a method for improving soybean seed germination under NaCl stress. Background technique [0002] Soil salinization and secondary salinization seriously affect agricultural production and ecological environment. According to incomplete statistics from the World Food and Agriculture Organization, as of 2015, more than 20% of the world's land has been subjected to varying degrees of salinization. For plants, growth in salinized land will cause salt stress, such as a severe reduction in seed germination and emergence rates. Under salt stress, plants will undergo a series of changes in the external morphology and internal physiological and biochemical characteristics, such as germination is inhibited, plant leaf area decreases, the number of leaves decreases, and the content of abscisic acid increases, which is not conducive to the normal growth of plant...
