Allometric equations for estimating belowground biomass of Androstachys johnsonii Prain
BACKGROUND The belowground component of the trees is still poorly known because it needs labour- and time-intensive in situ measurements. However, belowground biomass (BGB) constitutes a significant share of the total forest biomass. I analysed the BGB allocation patterns, fitted models for estimating root components and root system biomasses, and called attention for its possible use in predic...
متن کاملEffect of Topping Trees on Biomass and Nitrogen Removal in the Thinning of Norway Spruce Stands
In Central Europe, full-tree (FT) harvesting is an increasingly common harvesting method in steep terrain harvesting due to the increased use of highly economical processor tower yarders. In conventional FT harvesting, nutrient removal from harvest sites is substantially higher than in cut-to-length (CTL) harvesting due to the extraction of nutrient-rich branches and foliage. One strategy to re...
متن کاملCytokinins in Norway Spruce Seedlings and Forest Soil Pollution
KRAIGHER H. & HANKE D.E. 1996. Cytokinins in Norway spruce seedlings and forest soil pollution. Phyton (Horn, Ausrtia) 36 (3): (57) (60). Cytokinins can correlate with pollution damage in spruce trees and also with different strains and species of their mycorrhizal symbionts. In our study, Norway spruce seedlings were grown in vitro on sterilized or nonsterile soil substrates from two different...
متن کاملAllometric Equations for Aboveground and Belowground Biomass Estimations in an Evergreen Forest in Vietnam
Allometric regression models are widely used to estimate tropical forest biomass, but balancing model accuracy with efficiency of implementation remains a major challenge. In addition, while numerous models exist for aboveground mass, very few exist for roots. We developed allometric equations for aboveground biomass (AGB) and root biomass (RB) based on 300 (of 45 species) and 40 (of 25 species...
