Genetic control of Eucalyptus urophylla and E. grandis resistance to canker caused by Chrysoporthe cubensis [PDF]

open access: yesGenetics and Molecular Biology, 2010
Chrysophorte cubensis induced canker occurs in nearly all tropical and subtropical regions where eucalypts are planted, causing losses in both wood quality and volume productivity, especially so in the warmer and more humid regions of Brazil. The wide inter and intra-specific genetic variability of resistance to canker among Eucalyptus species ...

Quality of Eucalyptus urophylla x E. grandis cuttings as a function of substrate

open access: yes, 2022
Considering the increasing demand for seedlings of plants for aforestation and the scarcity of raw materials for the substrates used for plant growth, it is necessary to evaluate new components and formulations that ensure the quality of seedlings. In this experiment the development and quality of production of Eucalyptus urophylla x E.

Development and survival of Bemisia tabaci MEAM1 (Hemiptera: Aleyrodidae) on Eucalyptus genotypes

open access: yesAgricultural and Forest Entomology, EarlyView.
This study provides the first experimental evidence of the biological performance of Bemisia tabaci MEAM1 on Eucalyptus genotypes. Development time was shortest and viability highest on soybean compared with the evaluated Eucalyptus genotypes. B. tabaci MEAM1 completed its development on Eucalyptus camaldulensis and Eucalyptus urophylla × Eucalyptus ...

Gene Expression Profiling in Eucalyptus Associates Phenylpropanoid Resistance to Teratosphaeria destructans

open access: yesPlant Pathology, Volume 75, Issue 3, May–June 2026.
Transcriptomic analysis of a resistant Eucalyptus genotype revealed that the phenylpropanoid pathway was activated in response to Teratosphaeria destructans infection. Analysis in vitro showed contrasting effects of compounds produced. Chlorogenic acid completely inhibited germination of T.

Across-rotation genetic analysis and multitrait selection in a cloned cross of <i>Eucalyptus urophylla</i> × <i>E</i>. <i>tereticornis</i>. [PDF]

open access: yesFront Plant Sci
Clonal testing is crucial for estimating genetic parameters and selecting elite clones. However, few studies have tested clones over two or more rotations. In this study, a clonal trial of the sibs from a Eucalyptus urophylla × Eucalyptus tereticornis cross was used for genetic parameter analyses and multitrait selection based on traits such as across ...
