Abstract
Pear decline (PD) phytoplasma populations were examined over one year in non-symptomatic pear trees with HW620 scions grafted onto three different rootstocks: OH×F87 (PD resistant), OH×F69 (PD susceptible), and Bartlett (PD susceptible). For all three rootstocks, populations were at a maximum during late summer for leaves and shoots, and reached their minimum in mid-winter for shoots and early spring for leaves. In contrast, roots exhibited maximum populations in mid-winter and minimum populations in mid-spring. For all tissue types, PD populations were consistently lowest in trees grafted onto OH×F87 rootstocks, intermediate in those on OH×F69, and highest on Bartlett rootstocks, demonstrating that the type of rootstock significantly impacts PD populations. While OH×F87 rootstocks had the lowest populations, they can still contain relatively high PD populations, particularly during periods with maximum populations. Future research could explore the development of even higher levels of PD resistance in pear rootstocks to reduce PD populations in both the rootstock and scion.

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 it
