Abstract
A substantially microbe-free composition containing plant growth regulators is produced by culturing a fungal spawn on high carbohydrate medium under suitable conditions. The culture filtrate is sterilized, formulated, and used to enhance plant growth.
Claims22
A composition comprising plant growth regulating substances which composition is a sterilized culture filtrate recovered from a culture of the spawn of a Basidiomycete fungus incubated in a medium containing at least 10% available carbohydrate in the presence of long wavelength light, and in the substantial absence of agitation, wherein said medium has a BRIX value of 12-15 and further contains potassium ion and carotene, and wherein said filtrate is the liquid portion of said culture from which proteins have been denatured and removed.
A formulation for application to enhance plant growth and/or development which formulation comprises an effective amount of a composition comprising plant growth regulating substances, which composition is a sterilized culture filtrate recovered from a culture of the spawn of a Basidiomycete fungus incubated in a medium containing at least 10% available carbohydrate in the presence of long wavelength light and in the substantial absence of agitation, wherein said medium has a BRIX value of 12-15 and further contains potassium ion and carotene , wherein said filtrate is the liquid portion of said culture from which proteins have been denatured and removed and wherein said filtrate is optionally dried.
A method for preparing a composition comprising plant growth regulators, which method comprises sterilizing a filtrate of a culture of the spawn of a Basidiomycete fungus, whereby the culture has been grown in medium containing at least 10% available carbohydrate in the presence of long wavelength light and in the substantial absence of agitation, wherein said medium further contains potassium ion and carotene, and wherein proteins have been denatured and removed from the filtrate.
A method for preparing a composition containing plant growth regulators, which method comprises
- culturing the spawn of a Basidiomycete fungus in a medium containing at least 10% available carbohydrate in the presence of long wavelength light and in the substantial absence of agitation, wherein said medium further contains potassium ion and carotene;
- recovering a culture filtrate;
- denaturing soluble proteins in the filtrate and removing said denatured proteins;
- and
- sterilizing the remaining culture filtrate to obtain said composition.
