Abstract:

As part of a study of growth ring structure and growth periodicity in tropical trees, the formation of indistinct growth rings in young Hevea brasiliensis cultivated in Peninsular Malaysia was investigated. The cycle of shoot elongation included the following stages: apical growth (three phases), leaf maturation (two phases), and radial growth with no change in appearance (one phase). Correlation analysis of height and radial increment revealed a 6-week cycle and a 4- to 5-week delay between the height increment and the radial increment. The darker bands visible on wood disks had radially flat

AbstractThe article presents the results of the research on the peculiarity of response ofPinus sylvestrisL. growth in height and diameter in young pine forest stand of the Left-Bank forest-steppe of Ukraine under the influence of surface fire that happened in May 2011. Forestry taxation, comparative ecology, standard dendrochronological methods were used. Response of trees was different for the height growth and the radial increment in the year of fire (2011). The radial growth got depressed in the year of fire; at the same time, the height of trees showed positive trend of growth against the

The objectives of this study are to determine a trend of the radial growth at breast height (b.h.) and to compare the radial growth of trees of younger and older generations in the XX century for fir (Abies alba Mill.), beech (Fagus sylvatica L.) and pine (Pinus sylvestris L.) in the Świętokrzyski National Park. In the investigated area fir, 41 to 200–300 years of age at breast height, gradually regenerated its radial growth after a very strong decline during 1971–1990, and most likely the process of vitality reduction and death of its stands of various age is slowly coming to an end.

A high degree of stem taper limits the potential value of giant sequoia (Sequoiadendron giganteum (Lindl.) J. Buchholz) when grown for timber. I measured the effects of pruning to different height targets (0, 2.0, 3.5, and 5.5 m), resulting in the removal of 25%–85% of crown length, on the growth of 360 S. giganteum trees over 17 years. Height growth and growth of diameter at breast height were both negatively related to pruning intensity to a similar degree. Within the 17 years following pruning, repeated measurements of stem growth at different heights above the ground revealed that radial s

Three years after release, understory responses were best demonstrated by decreasing specific leaf area with increasing release level and by changes to height and radial growth increments. Clear-cutting the overstory stalled the height growth in fir for two seasons and radial growth at the tree

In association with TBX5 (T-box), SALL4 is responsible for the establishment and morphogenesis of the thumb. Pathogenic SALL4 variants have been reported to cause Duane-radial ray syndrome (also known as Okihiro syndrome), acro-renal-ocular syndrome and Holt-Oram syndrome.

Abstract:

Climate change and warming will potentially have profound effects on forest growth and yield, especially for pure stands in the near future. Thus, increased attention has been paid to mixed stands, e.g., pine and beech mixtures. However, the interaction of tree species growing in mixtures still remains unknown. Thus, the aim of this study was to investigate the impact of the interspecific and intraspecific competition to diameter, height, and crown width of pine and beech trees growing in mixtures, as well as to evaluate the impact of climatic indicators to the beech radial diameter increment.

Abstract:

Effects of pruning on the growth of Douglas-fir: findings from northwestern Germany Owing to Douglas-firs' insufficient self-pruning ability, for the production of high-grade wood, manual pruning is mandatory. Pruning of live branches increases the branch-free tree volume considerably. Branchiness is important for grading wood quality, but with pruning this detrimental characteristic loses its significance for the value of the Douglas-fir asset. In 1980, trials were conducted in the forest district of Ahlhorn (Lower Saxony, Germany) with three-year-old Douglas- firs to test the effects of live

Abstract:

Basal cankers induced by Cryphonectria parasitica (=Endothia parasitica) occur throughout the natural range of scarlet oak (Quercus coccinea) within Pennsylvania. Because colonization of scarlet oak is thought to be a long-term host/pathogen relationship, analyses were conducted to investigate effects of basal cankers on radial growth (expressed as area increment) at 1.4 m, breast height (BH). Moderately cankered oaks grew more slowly at BH than did noncankered trees. However, severely cankered scarlet oaks generally exhibited greater radial growth at BH than did noncankered trees.

Abstract:

Mixedwood forests are an ecologically and economically important ecosystem in the boreal forest of northern Canada. The objectives of this study were to (i) compare the ageheight relationships for dominant tree species growing on two contrasting soil types and originating from different disturbances (logging versus wildfire), and (ii) determine the influence of competition on tree growth. Eight stands were selected that encompassed two age-classes replicated on two soil types (clay loam and sand) in a split-plot design. Four of the eight stands originated from logging (2126 years old), and &

Radial variation in uniseriate ray characteristics of six Korean oak species was observed to provide information for wood identification and quality evaluation. Radial variations in uniseriate ray characteristics, such as ray height, number, and spacing, were observed at five growth ring intervals from the pith to near the bark using optical microscopy. The transition point between the juvenile and mature wood was evaluated using a segmented regression model. All species showed a comparable trend in uniseriate ray number and spacing, gradually decreasing from the pith to near the bark. Transit

Abstract Although most investigations of long-term growth trends of trees involve description of radial growth of trees, investigation of height growth of dominant and codominant trees also warrants attention for two significant reasons--the dependent variable is largely independent of stand density and it represents an index of stand productivity. Residuals from a height growth equation for jack pine (Pinus banksiana Lamb.) were used to examine long-term trends in height growth. No consistent long-term trend was apparent; however, a period of superior growth was identified during the 1960s. S

Thinning plays a vital role in controlling stand density of plantation forests to get quality wood and more ecological function.

Abstract Accurate tree ages are critical to a range of forestry and ecological studies. However, ring counts from increment cores, if not corrected for the years between the root collar and coring height, can produce sizeable age errors. The magnitude of errors is influenced by both the height at which the core is extracted and the growth rate. We destructively sampled saplings and small trees of red pine (Pinus resinosa Ait.) and combined within- and between-tree cross-dating to determine accurate rings counts and radial growth rates for 11 stem sections of each sample.

In order to realize the accurate and continuous digital measurement of tree diameter at breast height, this paper develops a low-power tree diameter at breast height continuous measurement device based on the magneto-resistive effect.

For a stand following Meyer's tables and reaching breast height in 1915, mean tree basal area increment increases steadily to a maximum in the early 1960's and then declines; mean radial increment is constant from 1925 to 1955 and then declines rapidly.

Trees within 10 meters of gaps grew more than trees from the reference sample, with no detectable differences in this depth caused by gap size (0.1 to 1.0 ha), sp
