摘要：Oak forest (Quercus petraea) in Dřevíč was selected for intensive year-round study of mycorrhizal activity and development of oak roots. At this study plot also activity of macromycetes was monitored based on their fructifications. This work presents quantitative data of active and inactive mycorrhizae that were collected monthly by the standard sampling method, thin root dry mass (roots up to 1 mm in diameter) and information about fungi species (qualitative and quantitative). Levels of active mycorrhizae were relatively stable year-round while inactive mycorrhizae showed statistically significant fluctuation with substantial increase after summer. A direct link between these two types of mycorrhizae can be probably explained by a shorter and variable longevity of active mycorrhizae during the season.
