Embodiment 1

[0027] Example 1. Effect of 1-octen-3-ol on postharvest rot of Actinidia jujube

[0028] experiment material:

[0029] The kiwi fruit (Longcheng No. 1) with uniform size, no disease, and eight matures from Dandong, Liaoning was selected. 1-octen-3-ol is domestic analytically pure.

[0030] Research methods:

[0031] Different concentrations (10 and 50 μl L -1 ) 1-octen-3-ol was fumigated for 2 days, then packed into small packages of 3 boxes each, and the natural onset was observed under low temperature and normal temperature conditions respectively. Measure once every 2 days under normal temperature conditions, and measure once every 7 days under low temperature conditions. 45 fruits per treatment.

[0032] Research result:

[0033] 1. The control effect of 1-octen-3-ol on the rot of Actinidia jujuba at room temperature

[0034] The result is as figure 1 shown. Depend on figure 1 It can be seen that under the condition of normal temperature, the disease of kiwifruit...

Embodiment 2

[0037] Example 2. Control effect of 1-octen-3-ol on postharvest blue mold and gray mold of Actinidia jujube

[0038] 1. Materials and methods

[0039] (1) Test material

[0040] The kiwi fruit (Longcheng No. 1) with uniform size, no disease, and eight matures from Dandong, Liaoning was selected. 1-octen-3-ol is domestic analytically pure. The expanded Penicillium and Botrytis cinerea are preserved by our research group.

[0041] (2) Fruit inoculation

[0042] Pick kiwi fruit with consistent maturity and no mechanical wounds. First use 2% sodium hypochlorite solution to soak and disinfect the fruit. After rinsing with tap water, stab a wound with a diameter of 3 mm and a depth of 3 mm at the equator of the fruit, and wipe off the overflowing juice. Inoculate each wound with 5 μL at a concentration of 1 x 10 5 Individual / mL Penicillium or Botrytis cinerea suspension. Put the inoculated kiwi fruit into an 8L lock box, and use different concentrations of volatile antibacter...

Embodiment 3

[0048]The influence of embodiment 3,1-octen-3-ol on the growth of Penicillium expansum and gray mold Botrytis cinerea

[0049] 1. Materials and methods

[0050] (1) Test material

[0051] 1-octen-3-ol is domestic analytically pure. The expanded Penicillium and Botrytis cinerea are preserved by our research group.

[0052] (2) Research methods

[0053] Inoculate Penicillium P.expansum and Botrytis cinerea B.cinerea on PDA plates, treat the two pathogenic bacteria with different concentrations of 1-octen-3-ol under airtight conditions, cultivate them at 25°C, and detect the colony diameter every day.

[0054] 2. Research results

[0055] 1-octen-3-ol has a significant inhibitory effect on the growth of P.expansum and B.cinerea, and the minimum inhibitory concentration is 20μl L -1 and 10 μl L -1 , can completely inhibit the growth of two pathogenic bacteria.

[0056] From the above experiments, it can be seen that:

[0057] (1) The 1-octen-3-ol fumigation treatment can s...

Abstract

The invention discloses an application of 1-octylene-3-alcohol in prevention and treatment of postharvest diseases of fruits. The 1-octylene-3-alcohol provided by the invention is applied to the following 1)-2): 1) using the 1-octylene-3-alcohol as a reagent for preventing and treating postharvest diseases of fruits; and 2) preparing a product for preventing and treating postharvest diseases of fruits. In the application, the fruits are at least one of kiwi fruits, apples, pears and grapes. The method has the following advantages: 1-octen-3-ol treatment can inhibit the natural morbidity of kiwi fruits under normal temperature and low temperature storage conditions; the bactericide has a good control effect on postharvest penicilliosis and gray mold of kiwi fruits under a normal temperature condition; and the action mechanism is to inhibit the growth of penicillium and grey mould.

Description

technical field [0001] The invention relates to the application of 1-octen-3-ol, in particular to the application of 1-octen-3-ol in the prevention and treatment of postharvest fruit diseases, and belongs to the field of fruit disease prevention and control. Background technique [0002] 1-octen-3-ol (English name 1-octen-3-ol; 3-Octenol) is also known as mushroom alcohol (Mushroomalcohol); vinyl pentyl carbinol (Vinyl pentylcarbinol); 1-vinyl hexanol (1- Vinyl hexanol) molecular formula C 8 h 16 O, the structural formula is CH 2 =CHCH(OH)CH 2 CH 2 CH 2 CH 2 CH 3 , is aliphatic unsaturated alcohol, the appearance is colorless to pale yellow oily liquid, with the aroma of mushroom, lavender, rose and hay. In nature, it mainly exists in mint, thyme and fresh mushrooms, and is a natural equivalent spice. It is also contained in trace amounts in fruits such as bananas and berries, beer, pork, river prawns, soybeans, and many other foods. Insoluble in water, soluble in ...
