The effect of age and sample position on eucalypt tree-ring width series
Publisher: Canadian Science Publishing
Date: 05-2008
DOI: 10.1139/X07-184
Abstract: In this study, we examine within-tree variance in proportionate tree-ring width (p rw ) and correlation between radii (r wt ), s les (r bh ), and trees (r bt ) in four eucalypt species common throughout eastern Victoria, Australia. In all species and sites studied, r wt and r bh differ significantly between cambial-age and s le-height classes. Differences between r wt and r bh are nonsignificant between tree-age or radial-azimuth classes. Significant differences in p rw exist between cambial-age, tree-age, and s le-height classes and between radii on different compass bearings. Whilst differences in r wt and r bh between cambial-age classes appears to be the result of variation in mechanical demands with increasing stem size, stem deformation may account for differences between s le-height classes. Variation in p rw appears to be due to stem geometry, stem eccentricities associated with root buttressing, and tree-age dependent variation in the rate of radial growth. No significant differences in r bt exist between s le-height classes. Analysis of the expressed population signal statistic indicates that site-level and species differences are far more significant than s le position on variance within tree-ring width series collected from eucalypts. We discuss the implications of the current work for eucalypt dendroclimatology.

Prescreening in large populations as a tool for identifying elevated CO2-responsive genotypes in plants
Publisher: CSIRO Publishing
Date: 2019
DOI: 10.1071/FP18087
Abstract: Elevated atmospheric CO2 concentration (e[CO2]) can stimulate the photosynthesis and productivity of C3 species including food and forest crops. Intraspecific variation in responsiveness to e[CO2] can be exploited to increase productivity under e[CO2]. However, active selection of genotypes to increase productivity under e[CO2] is rarely performed across a wide range of germplasm, because of constraints of space and the cost of CO2 fumigation facilities. If we are to capitalise on recent advances in whole genome sequencing, approaches are required to help overcome these issues of space and cost. Here, we discuss the advantage of applying prescreening as a tool in large genome×e[CO2] experiments, where a surrogate for e[CO2] was used to select cultivars for more detailed analysis under e[CO2] conditions. We discuss why phenotypic prescreening in population-wide screening for e[CO2] responsiveness is necessary, what approaches could be used for prescreening for e[CO2] responsiveness, and how the data can be used to improve genetic selection of high-performing cultivars. We do this within the framework of understanding the strengths and limitations of genotype–phenotype mapping.
Early-growth results within a Eucalyptus globulus breeding population suggest limited scope for selection focused on CO2 responsiveness

Abstract: Increasing [CO 2 ] may influence commercial crop and timber yield. While selection of genotypes sensitive to elevated [CO 2 ] (e[CO 2 ]) appears possible in agricultural crops, there is limited evidence for genotype-by-CO 2 (G × CO 2 ) interactions in commercial tree species. We examined [CO 2 ] responsiveness in 124 open-pollinated Eucalyptus globulus ssp. globulus ( E. globulus ) families with the aim of assessing whether G × CO 2 interactions are detectable in seedlings for early-age screening. Plants were grown in ambient (a[CO 2 ] ~ 405 μmol mol −1 ) and e[CO 2 ] (640 μmol mol −1 ) and harvested 25 days after germination. Total, shoot, and root dry weights were determined for each plant. Carbon isotopic discrimination against 13 C (Δ 13 C) was determined at the family level. We observed highly significant ( p 0.0001) increases in mean total, shoot, and root dry weights. Mixed-model equations were used to estimate the main and interaction effects of the G × CO 2 for each mass trait. The main effects from the mixed-model output ([CO 2 ] and in idual-tree effects) were significant for all traits. However, [CO 2 ]-by-in idual tree interactions were non-significant for all traits, indicating little G × CO 2 interaction. A secondary aim was to examine the correlation between greenhouse and mature-age growth from breeding trials that use common families conducted under ambient [CO 2 ]. These correlations were non-significant, suggesting early growth is not necessarily indicative of later-age responses. Our results suggest that while early growth of E. globulus is enhanced under e[CO 2 ], genotypes respond relatively uniformly to e[CO 2 ] and little opportunity exists for seedling-based selection at the population level based upon the response of plants during the first weeks of growth.

Eucalypt dendrochronology: past, present and potential
Publisher: CSIRO Publishing
Date: 2006
DOI: 10.1071/BT05039
Abstract: Dendrochronology has the capacity to provide unique insights into natural vegetation dynamics and yield climatological reconstructions. However, because of a persistent belief that eucalypts are unsuited to dendrochronological analysis, research interest in the genus has been limited. A thorough review of the eucalypt dendrochronological literature reveals that perceived limitations may be locally overcome. However, methodological problems associated with many studies mean that results are often difficult to interpret. Consequently, the dendrochronological potential of the eucalypts remains unresolved. To overcome this, a detailed dendrochronological reconnaissance of the eucalypts, drawing on established datasets, systematic study of in idual species and sites and examination of non-width-based tree-ring properties, is recommended.
