Within tree variation in anatomical properties of some clones of Eucalyptus tereticornis Sm.

Variation in Wood Properties and Growth in Some Clones of <i>Populus deltoides</i> Bartr. ex Marsh

“…Significant differences in average specific gravity of different clones of different species of Populus were reported [6,8]; in Tectona grandis [14] and in Eucalyptus tereticornis Sm. [15,16]. In contrary, non-significant radial and directional variations in specific gravity and fiber length in different clones of Dalbergia sissoo were reported by Pande and Singh [17], however these variations were significant due to height of the ramet.…”

“…Significant inter-tree variation in specific gravity of Dalbergia sissoo was reported by Pande [18] and in Lucanea leucocephala by Pande et al [19]. Similarly, significant differences among the different clones of different species in average fiber length were reported by many a worker [6,8,9,15,17,20]. Interclonal variation in vessel element dimensions in Dalbergia sissoo was reported by Pande and Singh [17]; in Populus deltoides by Chauhan et al [8] and in Tectona grandis by Rao and Shashikala [21].…”

Variation of wood density in Turkish hazel (Corylus colurna L.) grown in the Czech Republic

“…Nevertheless, the ambiguity of this issue was reported by other authors. Birch wood density rose up to the crown, followed by a drop in the upper part (Sennerby-Forsse 1989), and no trend was found even for the vertical variability in eucalyptus (Rao et al 2002). Bouriaud et al (2004) reported a negligible impact of annual ring width on the wood density value.…”

Feasibility study of quality plantation pulpwood breeding on fibre length, vessel element length and their ratio sought by within-tree variations in Eucalyptus trees

“…On the other hand, a weak pattern of decreasing fibre length from bottom to top was reported in E. nitens (Hudson et al, 2001) E. grandis x urophylla (Quilhó et al 2006) and E. globulus (Valente et al, 1992;Ridoutt & Sands, 1993;Jorge et al, 2000;Hudson et al, 2001). In addition, a mixed pattern was reported in E. tereticornis (Rao et al, 2002). The axial variation of fibre length is also considered to be concomitant with the variation of cambial initial length in the vascular cambium as reported in E. globulus (Ridoutt & Sands, 1993).…”

“…Within-tree variation of cell length property in Eucalyptus has been previously examined (Rudman, 1970;Valente et al, 1992;Ridoutt & Sands, 1993;Jorge et al, 2000;Hudson et al, 2001;Muneri & Raymond, 2001;Rao et al, 2002;Quilhó et al, 2006). However, while a few papers have been published on the radial variation of vessel element length (Dadswell, 1958;Ohbabayashi & Shiokura, 1990;Sharma et al 2005), there is little information on the variation in the axial direction.…”
