On short roots of aspen hybrids planted in forest soil, mycorrhizae were formed. Six years after planting, fruiting bodies of the fungal symbiont Leccinum aurantiacum began to appear, even during drought. The abundance of fruiting bodies corresponded with root system growth stages, suggesting a dependence on the development of the host's root system.
