| 摘 要： | 由疮痂病菌（Elsinoë arachidis) 引起的花生疮痂病，近年来在辽宁省大面积发生，严重制约花生产业的健康发展。本文对花生疮痂病菌生物学特性开展了系统研究。结果表明，花生疮痂病菌在PSA上菌落褶皱、隆起，生长缓慢，在最适培养基PSA上培养30d菌落直径仅为28.1mm，最适碳氮源分别为半乳糖和酵母浸粉，最适温度25℃，pH4~6时菌丝长势良好，黑暗有利于该菌的生长，菌丝致死温度为48℃；分生孢子萌发最适pH值为5，最适温度为25℃，最适碳源为1%葡萄糖，最适氮源为1%丙氨酸和1%甘氨酸，光照对分生孢子萌发差异不显著，分生孢子致死温度为47℃。

| Abstract: | Peanut scab caused by Elsinoë arachidis occurred widely in Liaoning Province and caused serious yield loss. The biological characteristics of E. arachidis were investigated to clarify the characteristics of the pathogen. The results showed that the colony morphology of E. arachidis on PSA appeared raised, wrinkled and grew slowly. The optimum medium for colony growth was PSA, best pH value was pH6, optimum temperature was 25℃ and grew well in darkness. The best carbon and nitrogen sources were galactose and yeast extract. The mycelia could not survive above 48℃ after 10min. The optimum temperature for conidial germination was 25℃, best pH value was 5. The best carbon and nitrogen sources were 1% dextrose, 1% alanine and 1% glycine. The conidia could not germinate above 47℃ after 10min. |
