Phytotoxicité de huit mycotoxines associées à la fusariose de l'épi chez le blé
Bibliographic record
Abstract
The study of eight mycotoxins from Fusarium spp. at concentrations ranging from 0 to 4.3 mg/L for deoxynivalenol, 3-acetyldeoxynivalenol, nivalnol, and a culture filtrate, and from 0 to 14.3 mg/L for T2 toxin, HT2 toxin, diacetoxyscirpenol, and zearalenone, demonstrate that trichothecenes are phytotoxic. The inhibition of coleoptile elongation by each trichothecene is well described by a linear equation and these compounds show differences in phytotoxicity. Deoxynivalenol and 3-acetyldeoxynivalenol are 2.5 times more toxic than T2 toxin, 8 times more toxic than HT2 toxin, and 13 times more toxic than diacetoxyscirpénol. The culture filtrate, which contains deoxynivalenol and 3-acetyldeoxynivalenol, is the most toxic to the coleoptile. A mixture of four purified trichothecenes, deoxynivalenol, 3-acetyldeoxynivalenol, T2 toxin, and nivalénol, revealed differences in trichothecene susceptibility among 11 wheat cultivars. Moreover, reduction of coleoptile elongation of these cultivars was correlated with scabsusceptibility (r = 0.74; P = 0.0068).

How this classification was reachedexpand
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.
