Embodiment 1

[0016] Take the seedlings with two true leaves of the same size, transfer them to five groups of 1 / 4 Hoagland nutrient solutions containing NaCl and different concentrations of hydrogen sulfide, and place the five groups of experiments in the light culture room for cultivation, and cultivate them for 3 days. indicators to measure;

[0017] The components of the nutrient solution in the five groups of experiments are as follows: 0, 100mM NaCl, 100μM NaHS+100mM NaCl, 200μM NaHS+100mM NaCl, 500μM NaHS+100mM NaCl, the mother solution of NaHS is 500mM mother solution B (prepared for current use), corresponding to Experiment 1-Experiment 5; each group of corn has 4 parallel experiments, and each parallel experiment contains 1 corn seedling.

[0018] see figure 1 , figure 1 It is the graph of the influence of hydrogen sulfide treatment of the present invention on the growth of corn seedlings under salt stress, wherein, 1 (a) is the effect of different concentrations of NaHS on the ...

Abstract

The invention discloses application of sodium hydrosulfide in improvement of the salt resistance of corn seedlings and belongs to the field of plant stress resistance. According to application of thesodium hydrosulfide in improvement of the salt resistance of the corn seedlings, by improving the activity of PM H+-ATPase of the corn seedlings, conveying of related ions of salt stress is improved to improve the salt resistance of corn, and growth of corn plants can be promoted. The operation is easily and conveniently conducted, a certain basis is provided for research on the salt resistance ofplants, and the sodium hydrosulfide has great economic benefits and social value. According to the application, the sodium hydrosulfide is adopted as a donor of hydrogen sulfide, double distilled water is directly used for being prepared into a mother solution, and the operation is conducted easily and quickly.

Description

technical field [0001] The invention belongs to the field of plant stress resistance, in particular to the application of sodium hydrosulfide in improving the salt resistance of corn seedlings. Background technique [0002] At present, the area of ​​soil salinization is gradually expanding, seriously reducing the world's food production. Salt stress damage to plants includes primary damage and secondary damage. The original damage includes ion poisoning (ion stress) and osmotic stress, and improving the salt tolerance of plants or crops has become an urgent issue. In the long-term natural selection process, plants adapt to the environment through their own adjustments. Studies have shown that plants have many mechanisms to adapt to the environment under salt stress, including growth, metabolism, osmosis, and cell signal transduction regulation. Corn is one of the most important food crops in my country, and it is a salt-sensitive crop. Studying the mechanism of corn salt...
