Estimating the absorptive Root Area in Norway Spruce by Using the Common Direct and Indirect Earth Impedance Methods

Aims Estimates of root absorption magnitude are needed for the balanced management of forest ecosystems, but no methods able to work on the whole tree and stand level were available. Modified earth impedance method was developed rec...

Estimation of relationship between root absorption area and leaf area index.

Estimation of alometric equations, derived from basic dendrological characteristics (DBH, tree height, crown length), which could be used for evaluation of root absorptive area (RAI), total leaf area (LAI) and foli...

Above- and below-ground tree parameters and their development after modelling of thinning in young elm stands

. The leaf area index of the stand was 5.6, the absorptive root area index was 1.7 and the total biomass of foliage was 8.5 Mg ha-1 prior to the treatment. The absorptive root fo...

Non-structural carbohydrate concentrations of Fagus sylvatica and Pinus sylvestris fine roots are linked to ectomycorrhizal enzymatic activity during spring reactivation

We evaluated whether changes in fine root non-structural carbohydrate reserves concentrations in the fine roots of Fagus sylvatica and Pinus sylvestris and potential as in the soil. Sugar concentrations in the ...
