Summary: In this study, factors influencing eucalyptus growth were systematically analyzed using plot records and satellite images. The primary restricting factor was found to be precipitation, contrary to common belief that temperature has the most impact. Key factors affecting timber growth, such as tree density, rotation period, and wood ownership, were identified and ranked. Optimal management and planting strategies were suggested for local farmers and policymakers.

Summary: In this study, a high-quality reference genome of E. urophylla x E. grandis was successfully constructed using a combination of Illumina, PacBio HiFi, and Hi-C sequencing platforms. The genome size was 545.75 Mb with a scaffold N50 length of 51.62 Mb. Genome evolution analysis revealed a recent whole-genome duplication event. Additionally, gene families associated with starch and sucrose metabolism, flavonoid biosynthesis, and plant-pathogen interaction were found to be significantly expanded in E. urophylla x E. grandis. This study provides valuable insights into the genome evolution, genetic improvement, and comparative biology of E. urophylla x E. grandis.

Summary: This study extracted essential oils from leaves of a unique hybridization of Eucalyptus grandis x E. urophylla, and evaluated its antioxidant, antimicrobial, and phytotoxic potential. The essential oil was found to be mainly composed of monoterpenes and possess good free radical scavenging ability, antimicrobial activity, and phytotoxicity against various plant pathogens. This research provides valuable insights for further exploration of the essential oil as a functional drug in agricultural and cosmetic industries.

Summary: The drying process of Eucalyptus wood is influenced by moisture content gradient and distribution, as well as moisture flow, which affect drying rate, shrinkage, and quality. Shorter samples have greater moisture content gradients and more uneven moisture distributions during drying.

Summary: The study found that fertilization and dry-season irrigation did not change the carbon distribution among all tissues in Eucalyptus urophylla x Eucalyptus grandis trees, but reduced the total soluble sugar (TSS) concentration in most organs. The primary existing form of non-structural carbohydrates (NSC) was total soluble sugar, which showed gradient differences from source organ to sink organ in spatial patterns.

Summary: This study examined the impact of different slash disposal methods on soil qualities. The results showed that the indicators of burning forest and no-burning forest were generally lower than those of the control group, but they differed in terms of soil properties. Burning forest can rapidly improve soil quality, while no-burning forest is more sustainable for the eucalyptus plantation.

Summary: The objective of this study was to evaluate the losses, survival, uniformity, and growth of a clonal planting of Eucalyptus grandis x Eucalyptus urophylla in Brazil during a short rotation, based on the different morphological characteristics of the seedlings as indicators of quality. The quality of seedlings was positively correlated with stem diameter, leaf biomass, and PH50 at 60 days of age, but these relationships lost significance over time. Only the old seedlings showed a difference in wood volume compared to the other treatments during the 36 to 64 month period.

Summary: This study used a SWAT model to investigate the hydrological impacts of Eucalyptus plantations for energy production in a humid subtropical watershed in Argentina, finding that shallow soils causing seasonal water stress were the most limiting factor for plant growth. An optimization algorithm was developed to identify the best location for Eucalyptus development with the highest productivity and least water impact. E. grandis plantations had higher evapotranspiration rates compared to existing land cover classes, resulting in a decline in streamflow, with different hydrological impacts throughout the year.

Summary: Continuous planting is the primary method for managing Eucalyptus plantations. The space-replacing time approach assesses growth parameters of Eucalyptus trees in China across generations, including height, DBH, slenderness ratio, trunk oblateness, and longitudinal growth strain. Factors influencing growth strain include height, slenderness, and surface longitudinal growth strain at breast height, with strong correlations observed. These parameters serve as growth strain indicators, and it is advisable to select trees with stable or slow growth rates and to avoid continuous planting without limits.

Summary: The research found that supercritical CO2 dewatering treatment can effectively reduce the moisture content of green wood, especially for shorter wood specimens. When the moisture content exceeds the fiber saturation point, the dewatering rate is faster, but the moisture distribution is not uniform.

Summary: Fast-growing Eucalyptus, Populus, and Corymbia species are being evaluated for their potential use in Short Rotation Woody Crop (SRWC) systems in the lower Southeastern USA, especially in Florida. This study characterized the wood properties of different clones and progenies of these species and evaluated their suitability for medium density fiberboard (MDF) production. The results showed significant variation in MDF properties among and within species, with some genotypes exhibiting superior physical and mechanical performance. Further investigation is needed to optimize the processing requirements for these genotypes.
