Seasonal variations of mycorrhizal colonisation of European beech, Fagus sylvatica L. and Norway spruce, Picea abies Karst., rootlets in two stands, were investigated by comparing ergosterol content and very-fine root tip counts for a 3 yr period. Significant correlations and interactions between three environmental factors, ‘year’, ‘season’ and ‘horizon’ and the measured data, were interpreted. It was shown that root tip counting together with ergosterol analysis of rootlets enables us to follow changes induced by the environment on a long-term basis.
