Embodiment 1

[0079] The progesterone was made into a 0 μmol / L progesterone solution with water for use.

[0080] Wheat seed is sowed in the plastic pot (diameter 8cm, height 9cm) that contains nutrient soil, 10 plants in every pot, every 3 days pour 1 / 4 Hoagland nutrient solution once, every pot sprays the progesterone solution 15ml of preparation after two weeks, Once a day, a total of 3 days, after spraying, grow samples and analyze 5 days later.

Embodiment 2

[0082] Progesterone was made into a 0.001 μmol / L progesterone solution with water for use.

[0083] Wheat seed is sowed in the plastic pot (diameter 8cm, height 9cm) that contains nutrient soil, 10 plants in every pot, every 3 days pour 1 / 4 Hoagland nutrient solution once, every pot sprays the progesterone solution 15ml of preparation after two weeks, Once a day, a total of 3 days, after spraying, grow samples and analyze 5 days later.

Embodiment 3

[0085] Progesterone was made into a 0.01 μmol / L progesterone solution with water for use.

[0086] Wheat seed is sowed in the plastic pot (diameter 8cm, height 9cm) that contains nutrient soil, 10 plants in every pot, every 3 days pour 1 / 4 Hoagland nutrient solution once, every pot sprays the progesterone solution 15ml of preparation after two weeks, Once a day, a total of 3 days, after spraying, grow samples and analyze 5 days later.

Abstract

The invention provides an application of progesterone as a drought-resistant agent for crops and a method for improving drought resistance of the crops. Research of a laboratory experiment, a pot experiment and a field experiment of the crops with three different volumes and in different environments shows that progesterone can affect wheat phenotype, malondialdehyde content in wheat, hydrogen peroxide content and activity of superoxide dismutase, catalase and peroxidase under the drought condition, can also affect net photosynthetic rate, stomatal conductance and fluorescence parameters of the wheat and can affect level of abscisic acid and cytokinin in the wheat and a root-shoot ratio of the wheat, thereby affecting the yield of the wheat finally. The application range of progesterone iswidened, and progesterone is not limited to medication of a human body and is applied to drought resistance and yield increase of the crops.

Description

technical field [0001] The invention relates to the technical field of plant hormones, in particular to the use of progesterone as a crop drought resistance agent and a method for improving crop drought resistance. Background technique [0002] Progesterone (progesterone), also known as progesterone hormone and luteinizing hormone, belongs to steroid hormones, and its molecular formula is as shown in formula (1). [0003] [0004] At present, progesterone is mainly used as medicine to promote the development and maturity of female secondary sexual characteristics, and is suitable for miscarriage protection, amenorrhea, dysmenorrhea, menstrual disorders and other diseases. However, progesterone is a naturally occurring compound with a low concentration in plants, and there are few reports on the development and application of progesterone in the field of plants. [0005] In view of this, the present invention is proposed. Contents of the invention [0006] The first ob...
