Five ectomycorrhizal fungi were studied in relation to the effects of applications of lime and wood ash to the growth substrate. Growth and survival of inoculated fungi in unsterile humus and relative root colonization frequency by inoculated and indigenous ectomycorrhizal fungi were measured. Growth of the fungi was tested in Petri dish systems with humus taken from a field site treated with lime and wood ash. The infection potential of the fungi was tested by introducing Pinus sylvestris L. seedlings into the growth systems. Paxillus involutus (Fr.) Fr. was the only fungus affected both by the pH increase, and by the different treatments applied, in all aspects of its ecology tested (growth and survival in humus, infection potential and competitive ability). No other fungus grew saprophytically, but they showed the similar changes in infection potential in response to pH whether lime or ash had been used.
研究了五种外生菌根真菌，探讨了在生长基质中施用石灰和木灰的影响。测定了接种真菌在未灭菌腐殖质中的生长和存活情况，以及接种和本地外生菌根真菌的相对根定殖频率。利用取自施用石灰和木灰的田间地块的腐殖质，在培养皿系统中测试真菌的生长情况。通过将樟子松幼苗引入生长系统来测试真菌的感染潜力。在所有测试的生态学方面（在腐殖质中的生长和存活、感染潜力和竞争能力），卷缘桩菇是唯一受到pH值升高和不同处理影响的真菌。没有其他真菌能腐生生长，但无论使用石灰还是木灰，它们在感染潜力方面对pH值的变化表现出相似的反应。
