(1) Stem biomass proportion increased with age, while branch and foliage biomass proportion decreased biomass allocation and most tree variables became steady after maturing. Biomass of stem, branch and foliage was estimated from destructive measurements, and with other tree dimensions, they were used to present the tree growth patterns. This study (1) tested the age independence of the PMT-based structure equations and (2) provided general information about the stability of tree structure with age.Ī total of 162 Scots pine and 163 Norway spruce trees in four age groups were analysed to test the age effect on the parameters of structure equations using a linear mixed model. However, more data concerning old-growth trees is needed to test the reliability and generality of the structure equations. Pipe model theory-based (PMT-based) structure equations have been incorporated in many process-based models. However, age dependence of parameters should be accounted for when applying the equations. Tree structure equations derived from pipe model theory (PMT) are well-suited to estimate biomass allocation in Scots pine ( Pinus sylvestris L.) and Norway spruce ( Picea abies Karst.). We were able to predict changes in the branchiness of the tree but not in the foliage mass supported per unit of branch area. Models based on Φ were simpler, since no other variables were able to explain between-stand variation in the presence of Φ. Models based on absolute height or tree diameter were usually weaker. The relative height of a tree in the stand (Φ) was the major factor that determined the variation in the relationship between the branch cross-sectional area and the stem cross-sectional area. The lowest site fertility class had a higher foliage mass to stem area ratio than better sites.
We studied how these relationships varied within and between stands. Our analysis allowed a separation of the relationship between stem and branch cross-sectional areas and the relationship between the branch cross-sectional area and foliage mass.

#Treesize free v2.4 windows#
Technical Title: TreeSize Free 4.2.2.473 for Windows Requirements: Overall, this handy little utility occupies minimal disk space, uses a small amount of system resources and has an intuitive interface on standard and touch enabled devices. The column view offers detailed information about files and folders including size, occupied disk space, number of files, last access, and owner.
The interface is clean and fresh showing you a stack of data including NTFS compression rates. You can easily navigate folders and their sizes by key, color coded visualisation bars. As TreeSize Free uses the MTF (Master File Table) for local NTFS drives, it guarantees ultra-fast, secure scans. It is also able to scan network shares and cloud drives.
TreeSize Free is pretty versatile as it is able to scan hard drives and mobile devices via MTP (Media Transfer Protocol) and WebDAV.
