Mycobiota on Wild Oat (<i>Avena fatua</i> L.) Seed and Their Caryopsis Decay Potential
Bibliographic record
Abstract
Wild oat is a serious weed in cereals that is difficult to control due to long-term survival in the weed seed bank. The mycobiota associated with dormant wild oat (Avena fatua L.) seeds buried for six months in a no-till wheat field were evaluated for their caryopsis decay potential. Of the 118 representative isolates tested, only 15% were found to have caryopsis decay potential. One isolate of Fusarium avenaceum and three isolates of Fusarium culmorum completely decayed wild oat caryopses within two weeks. Only a few isolates were susceptible to the antifungal activity from water or acetone extracts of wild oat hulls, suggesting that soluble chemicals from the hull play a minor role in resistance to decay. The procedures developed here can be used to isolate and screen individual organisms to determine their potential for seed decay and weed biocontrol. Accepted for publication 20 December 2010.

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.
