Abstract
Abstract A plant growth stimulator formulation including a substantially water-soluble concentrate solution of 1-triacontanol, a polar organic solvent, metal ions, and other plant growth substances. Metal ions disclosed in the present invention markedly increase the growth-stimulating effect of 1-triacontanol when applied to plant life resulting in crop yield increases which may be as high as 50 to 100%. The addition of certain plant growth substances such as auxins, gibberellins, cytokinins and kinins, and brassins and brassinosteroids alter the plants' response to 1-triacontanol formulations containing metal ions, and broaden the range at which said metal ions are effective in assisting 1-triacontanol in stimulating plant growth.
