Impact saisonnier sur la composition foliaire de<i>Lygeum spartum</i>L. en lipides totaux et en acides gras dans la région ouest-algérienne
Bibliographic record
Abstract
The leaf composition of Lygeum spartum L. in total lipids and fatty acids presents a seasonal quantitative variation. The principal components analysis realized in the fatty acids quantified and identified by gas chromatography showed that, in period of estival dormancy, the leaves of Lygeum spartum are characterized by a very low rates in lipids. They are made up primarily of saturated fatty acids of witch the palmitic, stearic and myristic acid are more representatives (group 1). These saturated fatty acids seem, made up a biochemical strategy of adaptation against the hydrous deficit and the extremes temperatures, witch the area of study know. On the other hand, in period of spring growth where the tufts of Lygeum spartum are made up specially of young leaves in the process of growth, we obtained relatively significant rates in lipids with prevalence of the unsaturated fatty acids of which the acids oleic, linoleic and linolenic are most characteristic and set up group 2.

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.
