“…Since our studied seedlings were grown in the same plantation, observed differences in the anatomical characteristics of vessel elements during the juvenile phase of growth might be explained by genetic variation among seed sources. In agreement with our results, Dünisch et al (2004) reported a genetic control on the anatomical characteristics of vessel elements in two leaf-morphotypes of Ilex paraguariensis from south Brazil.…”

We attempted to observe differences in vessel element anatomy, and physiological and morphological traits of leaves in Fagus crenata seedlings originated from seven different provenances grown under the uniform environmental conditions. We also investigated the relationships between the anatomical characteristics of the vessel elements and physiological plus morphological traits of leaves in Fagus crenata seedlings. To carry out the experiments, Fagus crenata samples were prepared from Chichibu Research Forest of Tokyo University. For anatomical studies of the vessel elements, vessel number per mm 2 , average vessel area, and the percentage of vessel area from the pith to the bark side were measured. We also measured transpiration rate, stomatal conductance, leaf area, leaf thickness, leaf dry mass per unit leaf area and leaf density for foliar studies. The anatomical characteristics of the vessel elements as well as the physiological and morphological traits of leaves were noticeably different among provenances. In addition, we found significant correlations between the foliar characteristics not only with vessel number per mm 2 , but also with vessel area percentage and sum of the (vessel area) 2 , theoretical hydraulic conductivity, from the pith to the bark side. Therefore, we concluded that variations in physiological and morphological traits of leaves in response to provenance variation were in correspondence with vessel number per mm 2 as a parameter that determines the total vessel area and consequent water hydraulic conductance in Fagus crenata as a diffuse porous hardwood.

“…The values of the vessel diameter indicated an increase in the pith-bark direction. This tendency was also verified by Dünisch et al (2004), Chagas et al (2007), Roque and Tomazello Filho (2009) and Melo et al (2013). Carlquist (1989) reports that the increase in vessel diameter in the radial direction (pith-bark) as a function of the tree'sage can be considered an anatomical adaptation of the xylem to increase the sap volume, and to consequently increase its photosynthetic capacity.…”

The characterization of wood anatomy and proprieties can provide subsidies for rational use of tree species. Enables, oftentimes, the definition of technological potential of wood - and wood products - through the assessment of quality information and also allows it´s correct identification, contributing to the timber production chain. The objective of this study was to contribute to the knowledge about wood properties of the Cerrado biome (Brazilian savanna) species trough the anatomical characterization and determination of density profile. Twenty trees species belonging to thirteen families occurring in Pirenópolis, Goiás and Brasília, Federal District, Brazil, was selected and radial samples were removed from the tree trunks at the DBH (1.30 m) in a non-destructive way using an incremental probe and a motorized extractor. The qualitative and quantitative anatomical parameters of vessels and fibers and the wood density were determined in the collected samples. Species presented fibers with mean values between 900.5 and 2052.9 µm for the length; 18.1 and 27.7 µm for the diameter; and 4.4 to 9.4 µm for the wall thickness. The species presented a variation in the vessel dimensions from 29.2 to 155.6 µm for the diameter; 17.7 to 32.5% for occupied area; and 2.6 to 165 to vessels.mm-2. The apparent density presented mean values between 0.36 and 1.21 g cm-3. The specie that presented the highest variation of wood density was A. fraxinifolium. According to the radial profiles two patterns of increasing and stable variation in the apparent density of the pith to bark were defined as a function of the wood anatomical characteristics.

“…The maximum diameter of vessels and tracheids tends to increase with cambial age (Fisher and Ewers 1995;Gartner et al 1997;Domec and Gartner 2002;Sperry et al 2006), although this was not true for holly oak (Quercus ilex L.) (Dünisch et al 2004). Maximum conduit size is limited by embolisms (Tyree et al 1994;Hacke and Sperry 2001;Gartner et al 2003).…”

The goal of maintenance pruning is the development of a tree canopy that meets a defined objective while minimizing the risk of failure. An indepth understanding of the primary functions of branches and how they influence canopy form is needed in order to assess the impacts of cultural practices such as pruning or plant spacing on canopy development. Allometric modeling describes the relationship between size and shape of organisms. This paper explores three allometric methods of modeling branch form (pipe model theory, fractal dimensioning, and power laws) and their potential in guiding pruning research. Additionally, two principal functions of plants—hydraulic and mechanical—are discussed in light of their impact of stem and branch form.
