Embodiment 1

[0036] Example 1 Fresh-keeping test of trans-2-nonenal on plants

[0037] (1) Experimental example: under the temperature condition of 25 ℃, put into the airtight container the fresh plant fruit that does not have any spot of pathogenic bacteria, wherein, place 0.1% trans -2-nonenal, wherein trans-2-nonenal is liquid, and trans-2-nonenal does not contact with the fruit, and the volatilized gas is filled in a closed container;

[0038] (2) Comparative example: repeat experiment example, wherein, do not place trans-2-nonenal, all the other conditions are equal;

[0039] (3) After 15 days, observe the appearance, color and luster of the plant fruits in the two containers, and whether there are germ spots.

[0040] In the above-mentioned Example 1, the mentioned plant fruits and corresponding observation results are shown in Table 1 below.

[0041] Table 1

[0042]

[0043] It can be known from the above Table 1 that trans-2-nonenal has a good fresh-keeping effect on plant f...

Embodiment 2

[0044] Example 2 Trans-2-nonenal is effective against plant pathogen 1 # ~9 # The test of the control effect

[0045](1) Prepare the corresponding purchased trans-2-nonenal standard substance with ethanol to prepare solutions with the following 12 concentration gradients: 1 μl / mL, 30 μl / mL, 60 μl / mL, 90 μl / mL, 120 μl / mL , 150μl / mL, 180μl / mL, 200μl / mL, 400μl / mL, 600μl / mL, 800μl / mL, 1000μl / mL;

[0046] (2) the solutions of above-mentioned 12 concentration gradients are respectively carried out following experimental example: the PDA culture medium is poured in the bottom of the petri dish dish of diameter 9cm, inoculate fresh phytopathogenic bacterium bacterium cake in the middle of the bottom of a part of petri dish dish, in another In a part of the bottom of the petri dish, take 100 μL of the solution prepared in step (1) and spread it on the petri dish, and buckle the bottom of the two petri dishes with the lids removed. At the bottom of the dish, the lower layer is the bo...

Abstract

The invention relates to application of trans-2-nonenal to the preparation of a plant preservative. Furthermore, the invention relates to application of trans-2-nonenal to the preparation of a prevention and treatment agent of plant diseases. Plants are dicotyledons and monocotyledons; particularly, the plants are rosaceous plants, solanaceae plants, rhamnaceae plants, fagaceae plants and grass family plants; and more particularly, the plants relate to apples, pears, loquats, strawberries, cherries, peaches, plums, tomatoes, eggplants, chilies, cucumbers, dates, Chinese chestnuts, wheat and corns. Trans-2-nonenal provided by the invention can be used for effectively preventing and treating the plant diseases, particularly preventing and treating plant fruit diseases, so that plant fruits can keep fresh for a long time.

Description

technical field [0001] The present application relates to the field of plant preservation, in particular, to the application of trans-2-nonenal in the preparation of plant preservation agents and in the preparation of plant disease control agents. Background technique [0002] Along with the improvement day by day of people's living standard, in more and more studies, adopt various ways to suppress plant aging, especially keep the freshness of the fruit after picking. [0003] There are various ways to preserve freshness, which are specifically divided into the following categories: ordinary preservation, constant temperature preservation, low temperature preservation, modified atmosphere preservation, vacuum preservation, and nano-preservation. In addition, plants are also preserved by preservatives. [0004] At present, the types of preservatives are mainly divided into the following categories: [0005] 1. Ethylene absorbent: It can inhibit respiration and prevent post-...
