Do same-aged but different height Norway spruce (Picea abies) clones affect soil microbial community?
2007
Abstract The influence of individual trees in monocrop forests on soil microbial communities is poorly understood. We measured basal respiration, substrate-induced respiration and phospholipid fatty acids (PLFA), bacterial growth rate with the 3 H-thymidine incorporation technique and fungal growth rate as 14 C-acetate incorporation into ergosterol to investigate whether slow- and fast-growing 12-year-old Norway spruce ( Picea abies ) clones have affected differently on their associated soil microbial communities. Understorey vegetation, soil chemical properties and elemental concentrations of needles were also determined. The slow- and fast-growing spruce clones differed in PLFA profiles, understorey vegetation and elemental concentrations in needles suggesting that spruce clones have directly or indirectly affected soil microbes.
