Abstract:

Studies were carried for 200 trees coming from eight pure pine stands aged 25–95 years, growing in a fresh mixed coniferous forest habitat, in the Murowana Goślina Forest Experimental Station (52°34′ N, 17°00′ E) in western Poland. The aim of the study was to determine the size of the assimilatory apparatus of single pines (Pinus sylvestris L.): weight of leaved twigs (ugc), needle weight (ic), the volume of leaved twigs (ugo) and needle volume (io) and its relationship with selected dendrometric and increment traits of trees.

Abstract:

Abstract Annual height increments are a very important characteristic of Scots pine. They have a direct effect on the determination of the dendrometric properties of a stand, such as volume increment. In the present study the data concern height increments of the main shoot in selected age classes of trees (age 72 to 92 years). A relationship is determined between the values of the increments and meteorological conditions such as temperature, precipitation and sunshine. On the basis of lasso regression analysis, precipitation in the year preceding the incremental season was shown to have the g

Abstract Individual-tree growth models basically consist of a number of equations (e.g., diameter or basal area increment model, height increment model, crown ratio model) to update tree parameters over time. These equations commonly are assumed to be independent, with parameters of each equation estimated separately rather than simultaneously with linear or nonlinear regression. However, the opposite assumption of interdependence seems more reasonable.

Much higher tree mortality in spruce was explained by a lower light intensity under the spruce stand canopy and higher tolerance of beech to shade.

The study presents the results of an analysis of the pine tree growth increments (height increment, dbh increment, basal area increment and volume increment) for a 5-year period. The study involved Scots pine trees of Kraft’s class 1, 2 and 3 (dominant stand) in stands of different age classes (II, III, V) growing in fresh mixed coniferous (BMśw) and fresh coniferous (Bśw) forest habitats. The multivariate analysis of variance was performed to assess the statistical significance of age and dominance of trees within a stand on their increment.

Abstract:

Basal-area increment and height growth of 30-year-old red spruce (Picearubens Sarg.) from 12 rangewide provenances growing in a plantation in northern New Hampshire were measured for a 3-year period (1986 through 1988) in which severe and (or) frequent winter damage to needles occurred. Growth of uninjured trees and injured trees were compared. Basal-area increments were successively smaller for groups of trees arranged in increasing order of average needle damage as a portion of the upper crown and number of years that the trees were injured. A similar pattern was observed for height growth,

Abstract:

A general form for expressing gross volume increment in terms of stand density is derived and tested with data from spacing trials in red alder (Alnus rubra Bong.), eastern white pine (Pinus strobus L.), longleaf pine (Pinus palustris Mill.), and loblolly pine (Pinus taeda L.). The equation relates the stand sum of individual-tree volume increment per metre height increment to a power function of quadratic mean diameter times tree density. The proposed equation fit the data best when the model included an intercept. Within each species, the fits were unbiased with respect to the independent va

The effects of heavy thinning on tree and stand increment were studied on sample plots in the artificially established Turkey oak stand, aged 51 years. Before thinning, extremely low height and diameter increments were recorded and also the process of revitalization and tree decline. Heavy thinning at the stand age of 46 years removed 38.0% of trees and 31. 4% of wood volume. Five years later, on the heavily thinned plot, a lower current increment of basal area and volume per ha for 10-13% was measured, while the percentage of volume increment increased for 13%, and the diameter increment of t

The aim of this study was to test the protection of the clone Populus deltoides cl. S-6-36, with several fungicides, against the loss of height and diameter increment. The idea was to protect the leaf immediately from the beginning of vegetation growth against the attack pathogens. By the planed treatments, the foliage would be protected against the fungal attack during the first two to three months of vegetation growth, which would presumably contribute to avoid the significant decrease of height and diameter increments.

The non-linear regression models of height curves for beech and fir were derived, where tree height is a function of tree diameter and model height for a selected diameter class.

The annual height increment of the shoot can be divided into two morphogenetic components: the number of stem units initiated in the bud prior to bud break and their mean length. Observations were made on the lateral shoots of 43 Abiescephalonica open-pollinated families from three provenances located in an experimental site in southern France. Genetic parameters of the two components were evaluated with an analysis of variance. Correlations both between components and with annual height increment were examined at the phenotypic, genotypic, and individual levels. Differences between provenance

The national level carbon sequestration estimation for urban trees generally relies on diameter at breast height (DBH) increments. However, limited research on urban tree growth has led to uncertain estimates.

Additionally, wedeterminded the aboveground woody biomass (AGWB) increment, which was calculated using the estimated DBH increment, and the accuracy of the

Abstract A formula is derived for the bias when an angle-count sample is used to estimate the mean of a tree variable that is correlated with the breast height diameter. This bias occurs, for instance, if average increment is estimated with increment cores from an angle-count sample. Estimation of mean increment for a given initial diameter is studied further by assuming that increments are log-normally distributed, in which case the sampling distribution is a mixture of three log-normal distributions.

These set-aside natural research plots have a smaller mean basal area diameter, but the number of trees is higher than in comparable managed forests. Due to the high-density of tree stands over the past thirty years, radial increment of spruce and larch has declined. To determine the influence of environm
