Problems solved by technology

So far, in the research on plant stress resistance of 5-hydroxytryptamine, the main focus is on its participation in the response to stress such as drought, salt damage, and disease resistance (Bowden K, Brown BG, Batty JE5-Hydroxytryptamine: its occurrence in cowhage.Nature 1954, 174:925-926; Byrne, M.E, "Making leaves?", Current Opinion in Plant Biology 2012, 15(1):24-30), however, how serotonin regulates these stress responses has not yet been clear research
In addition, the research on whether 5-hydroxytryptamine can relieve plant waterlogging is still blank

Embodiment 1

[0014] The present invention will be further described below in conjunction with embodiment, used material, reagent, as serotonin, NaCl and soil base fertilizer, all are commercially available goods.

[0015] A kind of application of 5-hydroxytryptamine in alleviating rape waterlogging stress, its steps are:

[0016] A. The experiment was carried out in September 2015 in the glass room of the Oil Crops Research Institute of the Chinese Academy of Agricultural Sciences. The pot experiment was used. The pot was a small red plastic barrel (19cm in diameter, 18cm in height), and the soil for the test was taken from the oil crops of the Chinese Academy of Agricultural Sciences. In Yangluo Experimental Base of the Institute, the cultivated layer has been evenly tested for many years. Each pot contains 3kg of air-dried soil, and the amount of soil base fertilizer is N 0.15g, P 2 o 5 0.15g and K 2 O 0.15g. After the soil is mixed, pot it, add water, and sow. Sow 10 seeds in each p...

Abstract

The invention discloses application of 5-hydroxytryptamine in relieving rape waterlogging stress. The application includes: 1), preparing 0.1-0.5g / L of water solution containing 5-hydroxytryptamine according to a weight ratio, weighing 5-hydroxytryptamine according to a weight ratio of 0.1:1000-0.5:1000, and dissolving in corresponding water; b), spraying leaves of rape seedlings under waterlogging stress at nightfall one time in each day for consecutive three times; 3), spraying 50ml of solution for each pot in each time to enable the plant leaves to be uniformly wetted, using a plastic thin film to cover soil in each pot and the adjacent pot during spraying in each time, and enabling sprayed liquid to enter the soil and small rape seedlings in the adjacent pots. The application is easy to implement, high in operability and capable of relieving damage of waterlogging to the rape seedlings, and waterlogging resistance of rape is improved remarkably.

Description

technical field [0001] The invention belongs to the field of rapeseed production, and more specifically relates to the use of 5-hydroxytryptamine in relieving rapeseed waterlogging stress. Background technique [0002] Rapeseed is one of the most important oil crops in the world. In my country, rapeseed is mainly distributed in the Yangtze River Basin (accounting for more than 85% of the total area of ​​rapeseed in the country). In this area, the rotation system of rice and rapeseed is mainly used. The growing season of rapeseed is warmed by the South Pacific. Due to the long-term confluence of humid air flow and northern cold air in the Yangtze River Basin, sometimes it rains continuously for 10-15 days, and the soil is seriously waterlogged, which often causes the water content of rapeseed to exceed the normal demand of rapeseed, resulting in frequent occurrence of rapeseed damage (Zhang Xuekun, Chen Jie, Wang Hanzhong, etc. Identification of genetic differences in moisture ...
