  • Method for regulating plant growth
    Patent number: 5238841
    Abstract: A process for increasing the rate of plant growth. Plants are treated with one or more acids, which are condensation products of glycolic and/or L-lactic acid. These acids also increase the concentration of chlorophyll, increase the rate of new plant formation when plants are propagated by tissue culture, decrease the amount of added nutrients required for plant growth, and protect plants against the toxic effects of salts. Certain of the acids are useful for increasing the rate of root formation in the plant.
    Type: Grant
    Filed: December 5, 1988
    Date of Patent: August 24, 1993
    Assignee: CPC International Inc.
    Inventors: Alan M. Kinnersley, Taylor Scott, III, John H. Yopp, George H. Whitten
