Wood density variations of E. urophylla clone among growth sites are related to climate

Canadian Journal of Forest Research, 2023
The Eucalyptus genus is extensively planted in Brazil for industrial use, and with the expansion of forest frontiers and climate changes, studies are needed on how these changes affect wood density (WD). The aim of this study was to evaluate the effect of some climate variables on WD of an Eucalyptus urophylla clone for a 4–5 year period.

Effects of Heat Treatment on the Machining Properties of Eucalyptus urophylla×E. camaldulensis

BioResources, 2014
The lumber of Eucalyptus urophylla×E. camaldulensis was heat-treated at either 180, 190, 200, or 210 ºC for 3 h. According to the national forestry standard methods for evaluating the machining properties of lumber, the machining properties (including planing, sanding, boring, mortising, shaping, and turning) of heat-treated and untreated control ...

WUSCHEL Transcription Factor: From Stem Cell Maintenance to Crop Improvement

Advanced Science, Volume 13, Issue 24, 27 April 2026.
This review synthesizes emerging insights into WUSCHEL (WUS) as a central regulator of plant stem cell fate beyond Arabidopsis, highlighting its roles in regeneration, somatic embryogenesis (SE), and stress adaptation across crops. It explores how WUS‐centered regulatory networks, genome editing, and AI‐guided strategies can be leveraged for precise ...
