Abstract

Provided is a compound and composition capable of increasing a sugar content in a fruit by a simple method, without being restricted by a cultivation area of a plant or a climatic environment. The agent for increasing a sugar content in a fruit of a plant comprises a compound represented by the formula MX as an active ingredient, wherein M represents alkali metal ion or alkaline earth metal ion, and X represents carbonate ion, hydrogen carbonate ion, acetate ion, citrate ion, succinate ion, phosphate ion, hydrogen phosphate ion, or pyrophosphate ion.

First claim

The invention claimed is:

1. A method for increasing a sugar content in a fruit of a plant, comprising applying to the plant a composition comprising:
a) a compound represented by the formula MX as an active ingredient; and
b) a surfactant comprising polyoxyethylene cocoamine, polyoxyethylene alkyl ether, polyoxyethylene sorbitan monolaurate, and diglycerin monooleate, and

wherein M represents potassium ion, and X represents carbonate ion or hydrogen carbonate ion, and wherein the plant is grape.

2. The method according to claim 1 , wherein the composition is applied in a period from 2 months before an expected harvest date or a harvest date of the fruit to 2 months after the expected harvest date or the harvest date.

3. The method according to claim 1 , wherein the compound represented by the formula MX is applied to the plant at a concentration in a range from 1 g/L to 100 g/L.

4. The method according to claim 1 , wherein the compound represented by the formula MX is applied to the plant at a dose in a range from 1 kg/ha to 30 kg/ha.

5. The method according to claim 1 , wherein the composition is applied only to a fruit portion of the plant.

6. The method according to claim 1 , wherein the composition is applied to a fruit of the plant after harvest.

7. A method for producing a fruit wine, comprising using as a raw material a fruit and applying to the fruit a composition comprising:
(a) a compound represented by the formula MX as an active ingredient; and
(b) a surfactant comprising polyoxyethylene cocoamine, polyoxyethylene alkyl ether, polyoxyethylene sorbitan monolaurate, and diglycerin monooleate, and
wherein M represents potassium ion, and X represents carbonate ion or hydrogen carbonate ion, and wherein the fruit is grape.

8. A method for producing dried grape, comprising adding to the grape a composition comprising:
(a) a compound represented by the formula MX as an active ingredient; and
(b) a surfactant comprising polyoxyethylene cocoamine, polyoxyethylene alkyl ether, polyoxyethylene sorbitan monolaurate, and diglycerin monooleate, and
wherein M represents potassium ion, and X represents carbonate ion or hydrogen carbonate ion.
