Abstract

Abstract: Morphologic traits, cultural characteristics and rDNA ITS sequences were studied for the pathogens of strawberry anthracnoses collected in Zhejiang Province. The results showed that Colletotrichum gloeosporioides was the predominant pathogen causing the disease in Zhejiang. PDA and PSA culture media were suitable for the growth of C. gloeosporioides and the optimal temperature was 25-30℃. It was found that spore germination rate was the highest in pH 6.0, however, the suitable pH to maintain mycelium growth was 6.0-7.0. The growth rate of mycelium was optimized using sucrose and fructose as carbon source and potassium nitrate as nitrogen source．
