Wood traits in parental and hybrid species of<i>Sorbus</i>
Bibliographic record
Abstract
The genus Sorbus is an example of taxonomic complexity arising from the combined effects of hybridization, polyploidy, and apomixis. In this study, a comparison of the diagnostic microscopic characteristics of wood, together with the quantitative traits of vascular anatomy, fiber morphology, and cell wall constituents in parental ( Sorbus aria , Sorbus aucuparia , Sorbus chamaemespilus ) and hybrid ( Sorbus haljamovae , Sorbus montisalpae , Sorbus zuzanae ) taxa, was undertaken to discriminate each one of the examined taxa from the other and also to examine relatedness among parental and hybrid taxa. Chemical profiles of the degree of polymerization of cellulose were found to be the discriminating chemotaxonomic marker for all taxa. Sorbus haljamovae was determined to be the only taxon distinctively identified microscopically and distinguishable from the other examined taxa. The use of cell wall constituent traits provided a better segregation of hybrid taxa from their putative parental species than did the application of vascular anatomy variables. Sorbus zuzanae and Sorbus haljamovae formed isolated clusters that were distinctively segregated from all the other examined taxa. The results of this study indicate that the majority of wood traits in Sorbus hybrids do not exhibit an intermediate position between the parental taxa.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
