Physiological and morphological variation of <i>Gremmeniella abietina</i> from Spain
Bibliographic record
Abstract
Summary Gremmeniella abietina isolated from Pinus halepensis in Spain was characterized based on disease symptoms and conidia morphology. The disease symptoms, which became more evident in the spring, included drying up of needles and branches with some distortion of terminal twigs, resulting in dieback and sometimes to death of trees of all sizes. Variation in conidia size and growth rate was investigated between 15 isolates from Spain, and the conidia morphology was compared with four isolates from Finland, four from Switzerland and three from the US. Great variation occurred between Spanish isolates both in growth rates and in conidia size. The growth rates of the isolates were greatest on malt agar amended with pine needle extract and at 15°C. The length and the width of the conidia of the isolates from Spain ranged between 10.7–44.8 and 1.5–4.4 μm, and most of them had three septa. The results suggest that the isolates from Spain do not belong to the Alpine biotype, and the disease symptoms caused by these isolates resembled those of the European biotype.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
