Combining ability of elite clones of Eucalyptus grandis and Eucalyptus urophylla with Eucalyptus globulus [PDF]

Genetics and Molecular Biology, 2007
In Brazil, eucalyptus breeding programs for cellulose production has used two species, Eucalyptus grandis and Eucalyptus urophylla. Nevertheless, it would be useful to introgress alleles from other species to improve wood quality and volume.

Genes expression profiles in vascular cambium of Eucalyptus urophylla × Eucalyptus grandis at different ages. [PDF]

BMC Plant Biol, 2023
Abstract Background Wood is a secondary xylem generated by vascular cambium. Vascular cambium activities mainly include cambium proliferation and vascular tissue formation through secondary growth, thereby producing new secondary phloem inward and secondary xylem outward and leading to ...

Silicon attenuates nutritional disorder of phosphorus in seedlings of Eucalyptus grandis × Eucalyptus urophylla. [PDF]

BMC Plant Biol
Abstract Background Nutritional disorders of phosphorus (P), due to deficiency or toxicity, reduce the development of Eucalyptus spp. seedlings. Phosphorus deficiency often results in stunted growth and reduced vigor, while phosphorus toxicity can lead to nutrient imbalances and decreased physiological function.

Is There a Relationship Between Secondary Metabolites of Leaves and the Growth of Eucalyptus Species? [PDF]

Physiol Plant
ABSTRACT Flavonoids are essential molecules that affect plant growth and development and act as defense mechanisms against biotic and abiotic factors. This study aimed to assess whether the content of flavonoids in different species of Eucalyptus is related to tree growth.

Site Classification of Eucalyptus urophylla × Eucalyptus grandis Plantations in China [PDF]

Forests, 2020
Background and Objectives: It is important to match species needs with site conditions for sustainable forestry. In Eucalyptus urophylla × Eucalyptus grandis plantations in southern Yunnan, China, species-site mismatches have led to inappropriate expansion and management, which has degraded forests and decreased efficiency in plantation production ...

Drying Characteristics of Eucalyptus urophylla × E. grandis with Supercritical CO₂. [PDF]

Materials (Basel), 2020
Supercritical CO2 (ScCO2) is a drying medium with excellent solubility and mass transfer efficiency. Supercritical CO2 drying (SCD) can remove the water of wood rapidly and prevent a change of microstructure caused by capillary tension in the drying process. In this study, Eucalyptus urophylla × E.

Genetic Resistance to Rust of Eucalyptus urophylla Progenies [PDF]

Floresta e Ambiente, 2018
This study assessed the genetic variability in open-pollinated progenies of Eucalyptus urophylla for resistance to rust (Puccinia psidii). The progeny trial was conducted on a statistical randomized block design with 20 progenies, five plants per plot, and nine replications.

Analysis of transcriptome and differential expression of different types of calli of Eucalyptus urophylla × Eucalyptus grandis. [PDF]

PLoS One
Eucalyptus urophylla X Eucalyptus grandis is an important afforestation hybrid clone that supports wood safety in China. To explore the mechanism of callus formation and differentiation of different types of E. urophylla × E. grandis, we cultivated four different types of E. urophylla × E.

Light quality in micropropagation of Eucalyptus grandis × Eucalyptus urophylla

Scientia Forestalis, 2020
The importance of eucalypts species and their interspecific hybrids has been evidenced in forestry programmes due to their wood quality and adaptation to diverse environmental conditions. To solve the limiting factors in the in vitro cultivation of the A211 clone of Eucalyptus grandis Hill ex Maiden × Eucalyptus urophylla S. T.
