Behavior of Eucalyptus urophylla and Eucalyptus citriodora Seedlings Grown in Soil Contaminated by Arsenate [PDF]

Revista Brasileira de Ciência do Solo, 2016
ABSTRACT Persistent areas of tailings and deposits from coal and gold mining may present high levels of arsenic (As), mainly in the arsenate form, endangering the environment and human health. The establishment of vegetation cover is a key step to reclaiming these environments.

Potential drivers of fast growth in Paulownia

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 516-529, March 2026.
Trees in the genus Paulownia play a crucial role in sustainable forestry, rural economic development, and carbon mitigation due to their rapid growth, exceptional hardwood properties, and prominent carbon sequestration capacity. This review highlights the societal value of Paulownia trees and synthesizes several potential drivers of extraordinarily ...

Air-drying of seven clones of Eucalyptus grandis × Eucalyptus urophylla wood

BioResources, 2019
Selecting clones with the best genetic material is one goal of eucalyptus breeding programs. Understanding the variations between the wood from different hybrid clones during drying is necessary to process improvement. This study aimed to select eucalyptus clones for lumber production based on their drying defects. From a plantation in Brazil, 42 trees

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 ...

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 ...

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.

Compatibility and ectomycorrhiza formation among Pisolithus Isolates and Eucalyptus spp Compatibilidade e formação de Ectomicorrizas entre Isolados de Pisolithus e Eucalyptus spp

Revista Brasileira de Ciência do Solo, 2005
Twenty-nine isolates of the ectomycorrhiza fungus Pisolithus sp. from different geographical and host origins were tested for their ability to form ectomycorrhizae on Eucalyptus grandis and E. urophylla seedlings under greenhouse conditions.

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 ...
