Abstract We studied the impacts of site, stand and tree variables on diameter growth beech trees ( Fagus sylvatica L.) carbonate bedrock examined to what extent regional model can be used at forest type level. Based 12,193 permanent sampling plots (500 m 2 each) with 94,770 trees, we first developed a linear mixed-effect periodic increment level (Dinaric region, Slovenia, 1.7 thousand km ). Sub...

Black locust is one of the most commonly planted exotic tree species in world. It has a crucial role mitigating negative effects climate change. Its increment analyses have key forest planning. Increment added to wood stock over and again, only this continuous replenishment makes sustainable management possible. This study presents results analysis periodic annual (PAI) by diameter (dbh) volume...

Atmospheric pollution critically affects forest ecosystems around the world by directly impacting the assimilation apparatus of trees and indirectly by altering soil conditions, which subsequently also leads to changes in carbon cycling. To evaluate the extent of the physiological effect of moderate level sulfate and reactive nitrogen acidic deposition, we performed a retrospective dendrochrono...

This paper presents distance-independent diameter growth models for Sal (Shorea robusta Gaertn. f.) in Kankali Community Forest, Chainpur VDC, Chitwan. As the basis for modelling, stem discs were cut 0.3 m above-ground for a sample of 80 trees that had recently been felled. Growth rings were measured along four radii and, except for the outer part of a few discs originating from old trees, indi...

This research was conducted in the growing season at an orchard Faculty of Agricultural Engineering Sciences Summel district Duhok governorate (Kurdistan region- Iraq) (2022) to examine effects basin irrigation, DAP supply, and Max-Gro foliar spray, fish irrigation on vegetative development leaf nutritional content three-year-old plum trees cv.Samarra. The experiment included three factors, fir...

Variation in tree stem diameter results from reversible shrinking and swelling and irreversible radial growth, all processes that are influenced by tree water status. To assess the causal effects of water and temperature on stem radial variation (DeltaR) and maximum daily shrinkage (MDS), the diurnal cycle was divided into three phases: contraction, expansion and stem radius increment. Diurnal ...

Aim of study: Understanding the factors that control tree growth in successional stands is particularly important for quantifying the carbon sequestration potential and timber yield of secondary tropical forests.
