| Abstract: | The pathogenic fungus of the brown root disease of rubber trees(Hevea brasiliensis) is Phellinus noxius Corner, and its biological characteristics were observed. This fungus showed an optimum mycelial growth when cultured at 28℃ with the pH 6 to 7, and it could effectively use parts of carbon and nitrogen sources, with the best carbon resource being D-fructose and yeast extract and the best nitrogen source being L-asparagine. Light treatment had significant effects on mycelial growth. Darkness is good for mycelial growth while light and black light have an inhibitory action against mycelial growth. The lethal temperature for the mycelium is 55℃ for 10 minutes. |
