RELATIONSHIP BETWEEN THE ANATOMY AND DRYING IN Eucalyptus grandis X Eucalyptus urophylla WOOD [PDF]

Revista Árvore, 2016
ABSTRACT Drying is an important step to using wood and anatomical characteristics influence this process. Thus, the objective of this work was to evaluate the relationship between anatomy and wood drying. Samples with 2 x 2 x 4 cm were obtained from eight Eucalyptus urophylla x Eucalyptus grandis clones at 1.3 m height to evaluate the anatomy and ...

Shade and Drought Shape Stomatal Kinetics in Beech Saplings

Physiologia Plantarum, Volume 178, Issue 2, March/April 2026.
ABSTRACT Stomata and photosynthesis respond at different rates to rapid changes in light availability, resulting in different dynamics of water and carbon fluxes. Here, we investigated how growth conditions, drought, and potassium availability affect the dynamics of stomatal conductance and photosynthesis in response to rapid changes of irradiance in ...

Efficient Regeneration of Eucalyptus urophylla x Eucalyptus grandis from Stem Segment [PDF]

Brazilian Archives of Biology and Technology, 2012
The aim of the present study was to establish an efficient regeneration system for the hybrid E. urophylla x E. grandis by means of organogenesis. Stem segments from seedlings were used as explants and cultured in a modified Murashige and Skoog medium (MS), supplemented with 13.2 µM N-phenyl-N'-[6-(2-chlorobenzothiazol)-yl] urea (PBU) and ...

Coevolution and Functional Effects of Endosymbiotic Rickettsia in Leptocybe invasa Fisher & LaSalle (Hymenoptera: Eulophidae) Across China

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Two distinct lineages of L. invasa and the dominant endosymbiont, Rickettsia, was identified, followed by an analysis of its infection density across various developmental stages and tissues of L. invasa. Furthermore, two distinct strains of the Rickettsia endosymbiont were detected, and the phylogenetic relationships between these strains and their L.

Cellular antioxidant activities of polyphenols isolated from Eucalyptus leaves (Eucalyptus grandis×Eucalyptus urophylla GL9)

Journal of Functional Foods, 2014
An activity-guided isolation process was performed to identify the antioxidant constituents of Eucalyptus leaves (Eucalyptus grandis × Eucalyptus urophylla GL9). The ethyl acetate extract showed the highest activity in scavenging DPPH radical among five different fractions extracted from 70% aqueous ethanol extract of Eucalyptus leaves.

Effects of eucalyptus thinning on soil chemical attributes in an unfertilized silvopastoral system 6 years after thinning

Soil Science Society of America Journal, Volume 90, Issue 1, January/February 2026.
Abstract Tree thinning is a common practice in silvopastoral systems, but there is no standard percentage of thinning used by farmers. Moreover, it is unclear how the percentage of thinning affects soil chemical attributes throughout the soil profile and throughout the transect between eucalyptus lines.
