Physicochemical properties of fruit of chokecherry (<i>Prunus virginiana</i> L.), highbush cranberry (<i>Viburnum trilobum</i> Marsh.), and black currant (<i>Ribes nigrum</i> L.) cultivars grown in Saskatchewan
Bibliographic record
Abstract
Physicochemical properties of the fruit of chokecherry (Prunus virginiana L.), highbush cranberry (Viburnum trilobum Marsh.), and black currant (Ribes nigrum L.) were assessed from fruit harvested from replicated cultivar trials at Saskatoon, SK, and at Yorkton, SK, in 1999 and 2000. Fruit weight, total solids, soluble solids, pH, titratable acidity, percent pit, estimated percent flesh, and Hunterlab colour characteristics were measured. Fruit of the chokecherry cultivars ranged in their 10-fruit weights from 6.6 to 9.2 g, percent pit from 9.4 to 16.0%, estimated percent flesh from 17.2 to 23.7%, and pH from 3.86 to 4.25. Mean total solids and soluble solids contents were 35.2% and 18.3°Brix, respectively, and did not differ among the cultivars. Hue angle, chroma and L values of chokecherry fruit juice extracts ranged from 34.6 to 88.2°, 15.3 to 23.9, and 23.3 to 51.1, respectively. Fruit of the highbush cranberry cultivars ranged in their 10-fruit weights from 4.1 to 7.3 g, percent pit from 4.6 to 9.0%, estimated percent flesh from 10.9 to 14.0%, soluble solids content from 10.2 to 13.3°Brix, and pH from 2.89 to 3.13. The hue angle and L values of the fruit juice extracts of the highbush cranberry cultivars ranged from 16.0 to 18.2°, and from 15.5 to 21.3, respectively. Mean total solids content and L values were 18.9% and 18.0, respectively; both measurements did not differ significantly among the cultivars. Fruit of the black currant cultivars differed only in their 10-fruit weight, pH and titratable acidity which ranged from 7.5 to 12.8 g, 2.85 to 3.04, and 3.04 to 4.03%, respectively. Mean total solids and soluble solids contents of black currant fruit were 22.3% and 15.8°Brix, respectively. Black currant fruit juice extracts had a mean hue angle, chroma and L values of 13.2°, 12.6 and 9.8, respectively. Key words: Chokecherry, Prunus virginiana, highbush cranberry, Viburnum trilobum, black currant, Ribes nigrum, native fruit

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
