preparation example Construction

[0030] In a preferred embodiment, the preparation method of the quercetin plant aging accelerator comprises the following steps:

[0031] S1: Prepare quercetin mother liquor: weigh quercetin compound powder and dissolve it in a solvent to prepare quercetin mother liquor;

[0032] S2: Prepare 1 / 2 MS medium: weigh MS powder and dissolve it in distilled water, adjust the pH of the solution to 5.8-6.0, and prepare 1 / 2 MS medium;

[0033] S3: Prepare 1 / 2MS solution of 2-(N-morpholine)ethanesulfonic acid: Weigh 2-(N-morpholine)ethanesulfonic acid and add it to the 1 / 2MS medium to prepare 2-(N-morpholine)ethanesulfonic acid -morpholine) ethanesulfonic acid 1 / 2MS solution;

[0034] In the above steps, the reason for choosing 1 / 2MS solution to dissolve 2-(N-morpholine) ethanesulfonic acid is that this liquid medium can not only fully dissolve 2-(N-morpholine) ethanesulfonic acid, but also ensure the A certain osmotic pattern is formed to lay the foundation for quercetin to play its r...

Embodiment 1

[0044] The quercetin plant senescence accelerator comprises: the quercetin mother liquor whose concentration is 10mmol / L, the 2-(N-morpholine) ethanesulfonic acid 1 / 2MS solution that the concentration is 2.8mmol / L is mixed and made, 2-(N -Morpholine)ethanesulfonic acid 1 / 2MS solution is 2-(N-morpholine)ethanesulfonic acid dissolved in 1 / 2MS medium.

[0045] The specific preparation method is as follows:

[0046] S1. Prepare quercetin mother liquor: weigh quercetin powder, dissolve it in dimethyl sulfoxide, and prepare quercetin mother liquor with a concentration of 10 mmol / L for later use;

[0047] S2. Prepare 1 / 2 MS medium: weigh MS powder and dissolve it in distilled water, adjust the pH of the solution to 6.0, and prepare 1 / 2 MS medium;

[0048] S3. Configure 2-(N-morpholine)ethanesulfonic acid 1 / 2MS solution: weigh 2-(N-morpholine)ethanesulfonic acid and add it to the 1 / 2MS medium to obtain a concentration of 2.8mmol / L of 2-(N-morpholine)ethanesulfonic acid 1 / 2MS soluti...

Embodiment 2

[0051] The quercetin plant aging accelerator includes: a concentration of 8mmol / L quercetin mother solution, a concentration of 3mmol / L 2-(N-morpholine)ethanesulfonic acid 1 / 2MS solution mixed to make, 2-(N- Morpholine)ethanesulfonic acid 1 / 2MS solution is 2-(N-morpholine)ethanesulfonic acid dissolved in 1 / 2MS medium.

[0052] The specific preparation method is as follows:

[0053] S1. Prepare quercetin mother liquor: weigh quercetin powder, dissolve it in dimethyl sulfoxide, and prepare quercetin mother liquor with a concentration of 8 mmol / L for later use;

[0054] S2. Prepare 1 / 2 MS medium: weigh MS powder and dissolve it in distilled water, adjust the pH of the solution to 5.8, and prepare 1 / 2 MS medium;

[0055] S3. Configure 1 / 2MS solution of 2-(N-morpholine)ethanesulfonic acid: Weigh 2-(N-morpholine)ethanesulfonic acid and add it to the 1 / 2MS medium to obtain a concentration of 3mmol / 1 / 2MS solution of 2-(N-morpholine)ethanesulfonic acid in L;

[0056] S4. Configure ...

Abstract

The invention provides application of quercetin in a plant senescence promoter, belongs to the field of plant senescence promoters and application thereof, and can be used for preparing quercetin intothe plant senescence promoter to be applied to actual production so as to accelerate the senescence process of plants, especially crop leaves. The quercetin plant senescence promoter is prepared by mixing a quercetin mother solution and a 2-(N-morpholine) ethanesulfonic acid 1/2MS solution. A direct spraying application mode can be adopted, the aging process of plant leaves is accelerated, and noextra adverse reaction is generated to plants.

Description

technical field [0001] The invention belongs to the field of plant aging accelerators, and in particular relates to the application of quercetin in plant aging accelerators. Background technique [0002] Leaf senescence is a programmed cell death process, which is accompanied by a series of physiological and biochemical changes, including the decline of photosynthesis, the degradation of chlorophyll, the degradation of biological macromolecules, and the reuse of nutrients. Crop growth, nutrient accumulation and yield formation. Planned control of senescence in agricultural production not only improves crop growth and seed yield, but also improves its agronomic traits and stress resistance to a certain extent. [0003] At present, research on leaf senescence-related regulatory genes has achieved relatively satisfactory results. There are also a small number of reports on the application of some functional substances as plant senescence accelerators to plants, especially crop...
