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.

Method for regulating plant growth

Improved secondary metabolite production is achieved by culturing plant tissue and plant cells in a culture medium wherein the carbohydrates comprise a mixture of maltose and glucose.

Method and composition for plant tissue and cell culture

A plant food with superior growth promoting properties that comprises a mixture of steepwater and other sources of nitrogen, phosphorus, and potassium. The optimum proportion of steepwater and other materials in the plant food is determined by analysis of growth response using the technique of response surface methodology.

Plant food and method for its use

This invention relates to monoxanthates and dixanthates of dipropylene glycol and triethylene glycol. These xanthates increase both the rate of plant growth and the concentration of chlorophyll in the plants.

Method for regulating plant growth using xanthates

This invention relates to condensation polymers of thiolactic and thioglycolic acids. These polymers, as well as thiolactic acid, 2,2'-dithobisacetic acid, and 2,2'-dithiobispropanoic acid, increase both the rate of plant growth and the concentration of chlorophyll in the plant.
