Comparative Anatomical Responses of Tolerant and Susceptible European Plum Varieties to Black Knot Disease
Bibliographic record
Abstract
) plums equally. To understand the spread of the disease, histological analysis was performed in two different European plum cultivars (susceptible and tolerant). Light and scanning electron microscope (SEM) analyses confirmed the presence of the growing hyphae in the internal tissues of the susceptible trees. By using stereoscopic analysis with a fluorescence filter, we were able to detect the hyphae in the visible lesion area. At about 2 inches from above and below the knots, no spore or hypha were visible with the light microscope. However, SEM images showed strong evidence that the fungus is capable of migrating to adjacent vessels in the susceptible plum genotype. In fact, at that distance below and above the knots, conidia were detected inside xylem vessels suggesting a systemic movement of the fungus that has not been shown so far. No symptoms were observed in the resistant genotype. Starch granules, vessel occlusions, and lipid droplets were the main distinguishable characteristics between susceptible and tolerant varieties.

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.
