Abstract:
The biological characteristics of Akebia trifoliata(Thunb.) Koidz leaf spot pathogen were studied from medium, carbon source, nitrogen source, pH, temperature and light, and its biological controls were discussed briefly.The results showed that the optinal conditions for mycelial growth were PCA medium at 30 ℃,pH=6, and alternating 12 h light and 12 h dark.The rate of spore germination was the highest at CA medium at 30 ℃,pH=7 and 24 h light.This pathogenic can use variety of carbon sources and nitrogen sources, and the ammonium sulfate and ammonium chloride can inhibit the growth of pathogen hyphae.（Bacillus subtilis）SNUB16 can antagonize Alternaria tenuissima growth.
