ABSTRACT:
Provided is a method for the use of 10-oxo-trans-8-decenoic acid (ODA) as a fungal growth hormone to stimulate mycelial growth of cultivated mushrooms. A species of cultivated mushroom is selected and grown in a solid or liquid growth medium which has been supplemented with ODA to a concentration of 10.sup.-7 M to about 10.sup.-4 M. After culturing the mushroom the mycelium of cultivated mushroom is harvested. In addition to a method of using ODA, a method for the hormonal stimulation of fruiting in cultivated mushrooms is also disclosed. The ODA in this method is added to the casing layer of the compost which is mixed with mushroom spawn. Further, the ODA is added to the casing layer in aqueous solution after casing the compost.
