Abstract
Meadow saffron (Colchicum autumnale) is an undomesticated plant from whose seeds the alkaloids colchicine and colchicoside are extracted and used pharmaceutically. Research was conducted towards domesticating meadow saffron in which inter- and intra-genetic variability of accessions was studied. Colchicine, 3-demethylcolchicine and colchicoside were assayed in plants of six accessions collected from natural sites in eastern France. These were cultivated at two sites and studied during 1 or 2 yr. Plants from 70 initial transplanted corms of one accession were studied individually for 4 yr to determined intra-accession variability and, as spontaneous vegetative multiplication of corms occurred, comparisons among plants from one initial transplanted corm were also made. For the main characteristics, seed dry weight (SDW) per plant, alkaloid content and colchicine:colchicoside ratio, the inter-accession variability was lower than the intra-accession variability. The results suggest that vegetative propagation of selected genotypes could improve alkaloid content by about 80% and improve SDW per plant by about 300%. Key words: Colchicine, colchicoside, Colchicum autumnale, medicinal plant, genetic variability

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
