Embodiment 1

[0020] Example 1, the new application of a new compound with strigolactone and resveratrol as active ingredients in improving the resistance of Pingyi sweet tea to potassium ion stress.

[0021] Dilute the 1 mol / L ethanol solution of the complex of strigolactone and resveratrol with distilled water to prepare a 100 μmol / L aqueous solution of the new complex for use.

[0022] Sow Pingyi sweet tea seeds soaked for 24 hours in pots filled with vermiculite. After culturing for 20 days in a culture room with a temperature of 25°C and a light intensity of 6 lux, water the semi-culture solution for one week and the full nutrient solution for one week.

[0023] First, 32 Pingyi sweet tea seedlings with the same growth and six leaves were selected; then, the selected Pingyi sweet tea seedlings were divided into four groups, with 8 trees in each group; among them, three groups were test groups, and one group was a control group .

[0024] Pack the sterilized nutrient soil into small fl...

Abstract

The invention relates to a new application of a novel compound in improvement of the resistance of malus hupehensis to potassium ion stress. A product containing strigolactones and resveratrol as active ingredients is applied to a plant subject to the potassium ion stress, so that the ability of the plant to remove active oxygen can be remarkably enhanced, oxidative damage of the potassium ion stress to the plant can be relieved, and the ability of the plant to resist the potassium ion stress can be obviously improved.

Description

technical field [0001] The invention relates to a new application of a novel compound in improving Pingyi sweet tea's resistance to potassium ion stress. Background technique [0002] Salt stress is one of the important environmental factors affecting plant growth, crop yield and quality, and soil salinization is also the most serious global problem facing the world today. At present, more than 20% of the land in the world is affected by salinization, and this trend is still expanding. In my country, about 100 million hectares of soil are affected by excessive salt. Potassium ions are key factors involved in many physiological and biochemical reactions, and play an important role in maintaining cell activity, while excessive potassium ions can cause damage to plants, so intracellular potassium ions must be strictly maintained. [0003] Apple is one of the most widely cultivated fruits in the world, but plant growth and fruit yield are severely affected by the accumulation o...
