Application of 5-hydroxytryptamine to relieving oilseed rape salt damage stress

Abstract

The invention discloses application of 5-hydroxytryptamine to relieving oilseed rape salt damage stress. The application includes the steps that a, a 0.1-0.5 g / L water solution containing 5-hydroxytryptamine is prepared according to the weight ratio, and 5-hydroxytryptamine is weighed according to the weight ratio of 5-hydroxytryptamine to water being 0.1:1,000 to 0.5:1,000 and dissolved in the corresponding water; b, leaf surfaces of oilseed rape seedlings suffering from salt damage stress are sprayed, spraying is carried out at dusk once every day, spraying is carried out three days continuously, and the total spraying number is three; c, the amount of the solution sprayed to each pot every time is 500 mL, the leaf surfaces of the plants are wetted evenly, soil in the pots and the adjacent pots are covered with plastic films during every time of spraying, and the growth amount of the oilseed rape seedlings under salt damage stress is increased. The method is easy to carry out and high in operability, damage of salt damage to the oilseed rape seedlings can be relieved, and the salt tolerance capacity of oilseed rape is remarkably improved.

Description

technical field [0001] The invention belongs to the field of rapeseed production, and more specifically relates to a use of 5-hydroxytryptamine in relieving rapeseed from salt damage stress. Background technique [0002] Soil salinization seriously reduces crop productivity, which is a huge problem faced by agriculture in the world today (Huang Changyong, Soil Science, 2000 edition, Beijing: China Agricultural Press). Land salinization will make it difficult for plants to absorb water, wilting and death, affecting plant nutrient absorption, resulting in yield reduction (Chen Jie, Lin Qifeng, etc., Research Progress in Plant Salt Tolerance Physiology and Salt Tolerance Mechanism, Journal of Hainan University (Natural Science Edition), 2003, 21(2):177-182). Rapeseed is one of the most important oil crops in the world and the largest oil crop in China. It accounts for more than 50% of the oil production of domestic oil crops and plays an important role in maintaining "food sec...

Problems solved by technology

So far, in the research on plant stress resistance of 5-hydroxytryptamine, it has mainly focused on its participation in the response to stress such as drought, salt damage, and disease resistance (Bowden K, Brown BG, Batty JE 5-Hydroxytryptamine: its occurrence incowhage.Nature 1954, 174:925-926; Byrne, M.E, "Making leaves?", Current Opinion in Plant Biology 2012, 15(1):24-30), however, it is not yet clear how serotonin regulates these stress responses Research

In addition, the research on whether 5-hydroxytryptamine has a mitigating effect on plant salt damage is still blank
