Proanthocyanidins in Sea Buckthorn (Hippophae\nrhamnoides L.) Berries of Different Origins with Special\nReference to the Influence of Genetic Background and Growth Location
Bibliographic record
Abstract
Wild\nsea buckthorn berries from Finland (Hippophaë\nrhamnoides ssp. rhamnoides) and China (ssp. sinensis) as well\nas berries of two varieties of ssp. rhamnoides cultivated in Finland and five of ssp. mongolica cultivated in Canada were compared on the basis of the content and\ncomposition of proanthocyanidins (PAs). Among all of the samples,\nonly B-type PAs were found. The contents of dimeric, trimeric, tetrameric,\nand total PAs were in the range of 1.4–8.9, 1.3–9.5,\n1.0–7.1, and 390–1940 mg/100 g of dry weight, respectively.\nThe three subspecies were separated by three validated factors (<i>R</i><sup>2</sup>, 0.724; <i>Q</i><sup>2</sup>, 0.677)\nin the partial least squares discriminant analysis model. Significant\ndifferences in total PAs were found between the ssp. rhamnoides and mongolica samples (<i>p</i> < 0.05). In ssp. rhamnoides, samples grown in northern Finland were characterized by a high\namount of total PAs, typically 2–3 times higher than that in\nthe level found in southern Finland. In ssp. sinensis, altitude did not have a systematic effect on the PA composition,\nsuggesting the significance of the interaction between genetic background\nand growth location.

How this classification was reachedexpand
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.
