摘要

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 p H value of 2- 10,the optimal temperature and p H value were 25℃ and 7 for its growth and sporulation,respectively. Starch was the optimal carbon sources and peptone was the optimal nitrogen source for the growth and sporulation of bacterial colony,respectively; PSA and PCA were the optimal media for its growth and sporulation,respectively.
