文摘Biological characteristics of Alternaria tenuissima on Dendrobium sandidium Wall. et Lindl. were studied. The result showed that A. tenuissima on D. sandidium Wall. et Lindl. could grow at temperature 5 -35 ℃and pH value of 2 - 10, the optimal temperature and pH value were 25℃ and 7 for its growth and sporulation, respectively.
