摘要：

The occurrence of growing, dormant and dead/damaged mycorrhizae on stands of Norway spruce was followed from April 1985 to July 1987. It was found that numbers of growing mycorrhizae reached peaks in may and October in 1985 and were minimal during August. In 1986 the peaks occured in August and November with a minimum in September/October. These differences seemed to be related to weather. Detailed observations indicate that the distribution of living and dead/damaged mycorrhizae is subject to a high degree of spatial variation. Applying 2339 - 4796 kg ha-1 of a fertilizer, containing Ca, Mg and P, increased the proportions of living mycorrhizae. © 1990.
