摘要
杜仲灰斑病是福建省杜仲栽培区三明、龙岩等地的一种主要病害.经分离培养、接种试验,鉴定其病原菌为细交链孢(AlternariatenuisNees).菌丝生长最适温度为20~25℃;最适pH值为6.0~6.5℃;分生孢子在高湿条件下才能萌发;它能有效地利用多种碳源,但以葡萄糖为好;也能利用多种氮源,其中以蛋白胨为佳.
Grey spot is a major pethogen of Eucommia ulmoides in Sanming and Longyun areas in Fujian All virulent strains isolated from diseased leaves from this areas were identified as Alternaria tenuis Nees.The optimum temperature and optimum pH for mycelium growth was between 20℃ and between 6 and 6.5,respectively,High relative humidity was necessary for germination of the conidia.Thefungus grew better in sucrose and glucose as carbon source, and in peptone as nitrogen source.
