In boreal forest trees, nearly all the short roots are ectomycorrhizal. The functional importance of mycorrhizal roots is high since they form the interface for water and nutrient exchange between trees and fungi. Our research group found a positive relationship between mycorrhizal diversity and growth of Norway spruce (Picea abies) clones in a field. The mechanism behind the observed correlation is still, however, unknown. We propose to study growth performance, microbial associates and root architecture of 4-43 years old Norway spruce clones planted in spatially heterogeneous forest soils and homogenous agricultural soils. We hypothesize that i) long-term growth rate of the spruce clone is dependent on the spatial structure of the soil and that ii) microbiome of the progeny of the clones, particularly root endophytic fungi affect the inherent root architecture and susceptibility of the progeny to future ECM fungal symbiosis, and thereby their long-term growth rate.
