RÉSUMÉ

Hericium erinaceus is a popular culinary and medicinal mushroom in China because of its broad beneficial effects. In this study we evaluated the effects of stimulation with 7 growth regulators at 5 different concentrations on improving the production of nutritional and bioactive compounds by H. erinaceus. Results showed that among all the tested regulators, gibberellic acid (GA) increased protein content (165%), free amino acids (100%), polysaccharides (108%), and polyphenols (26%). Spraying nephthyl acetic acid increased polysaccharides and triterpenoids to 4.37 and 17.27 g/100 g, respectively. Spraying chitosan significantly increased polyphenols by 42%. The addition of triacontanol, indole acetic acid, and 2,4-dichlorophenoxyacetic acid improved the production of proteins, free amino acids, polysaccharides, and polyphenols, but not to the extent that GA did. These results indicate that adding certain growth regulators can effectively improve the production of nutritional and bioactive compounds in H. erinaceus.
