本文主要介绍了用人工合成培养基测定烟草黑胫病原菌的致死温度、最适生长的pH值和能够生长的pH值范围的方法及结果。对黄河等“适宜于马铃薯晚疫病菌的一种液体合成培养基”,在配方和实验方法上做了一些改进。通过实验,进一步证实了该菌在营养生长过程中钙素的重要性和三羧酸循环(TCA)中有机酸的重要性;该菌的营养生长并不需要较复杂的营养条件。
This article mainly introduces the method and result of determining the lethal temperature, optimum growth pH value and the growth of pH range of tobacco black tibiae by artificial synthetic medium. On the Yellow River and other “suitable for potato Phytophthora infestans of a liquid synthetic medium” in the formulation and experimental methods to make some improvements. The experiment further confirmed the importance of calcium in the vegetative growth and the importance of organic acids in the TCA. The vegetative growth does not require more complicated nutritional conditions.
