Problems solved by technology

However, in agricultural production, the antioxidant mechanisms in plants are often insufficient to remove stress-induced ROS in a timely manner, thus hindering plant growth.
[0005] Melatonin, also known as melatonin, melatonin, pineal gland, chemically named N-acetyl-5-methoxytryptamine, is an important plant endogenous active oxygen scavenger discovered only in recent years However, no one has studied the effect of melatonin on plant waterlogging stress

Embodiment 1

[0025] Example 1, the new application of a product with melatonin as an active ingredient in improving the resistance to waterlogging stress of Semen chinensis.

[0026] Dilute the 100 mmol / L melatonin ethanol solution with distilled water to prepare respectively 50 μmol / L, 100 μmol / L, and 200 μmol / L melatonin aqueous solutions for use.

[0027] Sow the seeds of Betia chinensis soaked in deionized water for 48 hours in a pot filled with vermiculite, and cultivate them in a culture room with a temperature of 25 °C and a light intensity of 6 lux for two weeks, then treat them with half culture solution for one week, and then use full The nutrient solution was treated for one week.

[0028] Firstly, 24 seedlings of T. japonica with the same growth and four leaves and one heart were selected; then, the selected seedlings of T. chinensis were divided into four groups with 6 trees in each group; among them, three groups were the test group and one group was the control group.

Abstract

The invention relates to novel application of melatonin in resistance to waterlogging stress of plants. A product which takes melatonin as an effective component is applied to a plant subjected to waterlogging stress to remarkably enhance the ability of the plant for eliminating ROS, alleviate oxidative damages on the plant caused by waterlogging stress and remarkably improve the ability of the plant for resisting the waterlogging stress, so that the yield and quality drop caused by waterlogging is reduced.

Description

technical field [0001] The invention relates to a new application of melatonin in improving plant resistance to waterlogging stress. Background technique [0002] Waterlogging is the main natural disaster. The precipitation in summer and autumn is concentrated and abundant. If the drainage of farmland is not timely, it is easy to cause crop waterlogging. When crops suffer from waterlogging, the level of reactive oxygen species in the crops will increase, breaking the original metabolic balance of reactive oxygen species. Excessively synthesized reactive oxygen species will damage the plant membrane system, causing great harm to crop physiology, and finally causing crop yield reduction. [0003] The root hypoxia caused by waterlogging will weaken the respiration of plant roots, affect plant water metabolism and the absorption of mineral elements such as potassium ions; and the reduction of potassium ion levels will in turn lead to the closure of stomata and affect water absor...
