INVESTIGATION OF CYANIDIN AND PELARGONIDIN CONTENTS IN THE GENUS FRAGARIA L.
Bibliographic record
Abstract
Cultivated strawberry (Fragaria x ananassa ) fruit contain primarily pelargonidin and little cyanidin. The antioxidant potential of cyanidin is reportedly twice that of pelargonidin. A High Performance Liquid Chromatography method was developed to assay fruit anthocyanidin content in 87 Fragaria accessions, including wild diploids and octoploids, cultivars, and two segregating populations. A cyanidin to pelargonidin ratio (CPRatio) greater than one was found only in diploids Fragaria vesca ssp. americana (confirming a previous report), F. viridis, and F. iinumae, and in three wild octoploid accessions: all F. chiloensis. The highest cyanidin contents were found in diploid F. viridis and in F. chiloensis ssp. lucida. During fruit ripening, pelargonidin content increased, while cyanidin content held steady. The results hold promise for breeding of cultivars with higher cyanidin content and with potentially higher antioxidant potential.

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.
