Abstract
A composition for use in the treatment for developing seedless fleshy berry of grapes. By treating the flower bunches of a grape tree with a composition containing gibberellin and cyclic 3',5'-adenylic acid in the form of an aqueous solution, it became possible to make seedless fleshy berry from grape trees belonging to varieties other than Delaware, namely belonging to Campbell-Arley, Berry A, Niagara, Kyoho, etc., from which seedless fleshy berry cannot be made by the conventional treatment with gibberellin.
Claims11
A process for developing seedless, fleshy berry of grapes which comprises contacting the flower bunches of grapes with an effective amount of an aqueous solution containing gibberellin and at least one cyclic 3', 5'-adenylic acid compound selected from the group consisting of cyclic 3', 5'-adenylic acid, alkali metal and alkaline earth metal salts of cyclic 3', 5'-adenylic acid, and derivatives of cyclic 3', 5'-adenylic acid, said gibberellin and cyclic 3', 5'-adenylic acid being present in the concentration of 10 to 300 p.p.m. and 1 to 10,000 p.p.m., respectively, and said derivatives of cyclic 3', 5'-adenylic acid being selected from the group consisting of 6-benzyl-cyclic 3', 5'-adenylic acid, 6-allyl-cyclic 3', 5'-adenylic acid, 8-bromo-cyclic 3', 5'-adenylic acid, 8-iodine-cyclic 3', 5'-adenylic acid, 9-methyl-cyclic 3', 5'-adenylic acid, N.sup.6, O.sup.2' -(dibutyl ester)-cyclic 3', 5'-adenylic acid and N.sup.6 -(butyl ester)-cyclic 3', 5'-adenylic acid.
