<p>Disclosed is a method for imparting stress tolerance to a plant, which can provide a plant with such stress tolerance that accelerates the growth of the plant under the environment where various stresses to the plant may occur. The method comprises the step of applying a plant stress tolerance-imparting composition to a plant that is placed under the cultivation conditions receiving a stress at a percentage plant stress of 111 to 200%, wherein the plant stress tolerance-imparting composition comprises a sugar derivative type of surfactant and water. In the plant stress tolerance-imparting composition, the sugar derivative type of surfactant comprises at least one sugar derivative type of surfactant having a structure selected from the group consisting of an ester of a sugar and a fatty acid, an ester of a sugar alcohol and a fatty acid, and an alkyl glycoside. The sugar derivative type of surfactant is contained in the composition in an amount of 85 to 100 wt% relative to the total amount of the components other than water contained in the composition.</p> |
