摘要
对6株剑麻茎腐病原菌黑曲霉菌生物学特性的研究结果表明，在不同种类培养基、pH值、温度、光照等培养条件下病原菌生长速率有差异，病原菌的孢子生长的温度范围为10～44℃，最适温度为32℃，菌落生长的最适pH值为9，全光照条件下菌落生长最适，分生孢子的致死温度为60℃，50 min。
The biological characters of six rotten sisal stem pathogens （ Aspergillus niger） were stud-ied in this paper.The results showed that there were differences for pathogen growth between different cultivation mediums, pH, temperature, humidity, illumination and so on.The growth temperature for As-pergillus niger ranged from 10℃to 44℃, and the optimal temperature was 32℃.The best value of pH for the growth of colonies was 9.The colonies grew perfectly under a complete illumination condition , and the lethal temperature for conidia was 60℃for 50 min.
