Apparent Increase in Biomass and Seed Productivity in Hemp<i>(Cannabis sativa)</i>Resulting from Branch Proliferation Caused by the European Corn Borer<i>(Ostrinia nubilalis)</i>
Bibliographic record
Abstract
The European corn borer (Ostrinia nubilalis Hübner), or ECB, is a major pest of hemp (Cannabis sativa L.). During the course of a study of hemp germplasm and cultivar accessions, the ECB attacked the vertical stem leader of hundreds of plants. At the site of invasion the main stem was typically destroyed, and the plant became strongly branched. Although the damaged plants were an average 9% shorter, mean shoot weight was 20% heavier. Seed productivity was also greater, based on a visual scale. The practical significance of such an “overcompensation” response to insect damage, with damaged plants growing more robustly and productively than their undamaged counterparts, is controversial. Certainly, some aspects of productivity, such as fibre quality, are detrimentally affected by the ECB. The insect showed a preference for larger plants, but was indifferent to the level of tetrahydrocannabinol, the chief intoxicant of C. sativa.

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.
