摘要
对毛壳属25个种50个菌株的最低生长温度、最适生长温度、最高生长温度、致死温度以及在最适生长温度下的菌落日生长速率进行了系统比较。结果表明,毛壳属不同的物种具有稳定的特征性最高生长温度,这一温度指标可作为该属物种鉴定,特别是区分形态相似种的重要生理性状;其他温度指标在种内变异大,在种间存在明显交叉,不具分类学价值。在此基础上,测定了42个种的最高生长温度,为毛壳属物种鉴定提供了一个重要的生理性状指标。
The minimum,optimum and maximum growth temperatures,fatal temperatures as well as the rate of colony growth at optimum temperatures for fifty strains belonging to twenty-five Chaetomium species were compared.The results revealed that each species possessed a stable and specific maximum growth temperature,which can be used for distinguishing Chaetomium species,particularly for the morphologically similar species.The other temperature features showed variation within a single species and obvious overlap between species,which are of little value in taxonomy.The maximum growth temperatures of 42 Chaetomium species were determined.The results provide a valuable physiological criterion for the delimitation of species in the genus.
