Early growth performance of salal (<i>Gaultheria shallon</i>) from various North American west-coast locations
Bibliographic record
Abstract
Salal is a native perennial evergreen shrub occurring from the panhandle of Alaska along the entire coast of British Columbia to southern California.In the North American west coast industrial forest it is considered a weed because it is a persistent, serious competitor with coniferous species.Intraspecific genotypic and phenotypic diversity of salal is not well known despite of its ecological and economic significance.A morphometric analyses within and among populations was performed in a statistically appropriate manner.Two-year-old container grown seedlings of 24 collections of salal from throughout the natural area of distribution in western North America were planted in a randomized complete blocks design (6 blocks) on a cleared 0.7 ha plot on Vancouver Island.Each of the 24 seedlots was planted once in each block with 24 plants per seedlot in April 1990.Shoot height and the number of buds prior to planting, the plant spatial volume (product of plant height and plant width on two perpendicular axes) in 1992 and 1993, the relative growth increment (1992)(1993) and the number of dead plants in 1992 and 1993 were subjected to analysis of variance.No differences among seedlots were detected for the relative growth increment and the number of dead plants in 1992 and 1993.Conversely, shoot height and the number of buds prior to planting as well as the plant volume in 1992 and 1993 showed statistically significant seedlot effects.Cluster analysis of these effects revealed greatest differences in plant response among the eastern-and southernmost collection and the remainder of the collections; i.e. three geographical races of salal may exist. Gaultheria shallon / geographical origin / experimental designRésumé -Potentiel de croissance initiale du Salal (Gaultheria shallon) de diverses régions de la côte ouest de l'Amérique du Nord.Le Salal est un arbuste autochtone pérenne à feuilles persistantes réparti depuis la péninsule de l'Alaska tout au long de la côte de la Colombie Britannique jusqu'au sud de la Californie.Dans les forêts industrielles de la côte ouest de l'Amérique du Nord, il est considéré comme une mauvaise herbe parce qu'il est persistant et un compétiteur sérieux des espèces de conifères.La diversité intra spécifique génotypique et phénotypique du Salal n'est pas bien connue malgré son importance écologique et économique.Une analyse morphométrique parmi ses populations a été réalisée selon les règles statistiques.Des semis de 2 ans, ayant poussé en conteneurs, provenant de 24 collections de Salal originaires des diverses régions naturelles de l'ouest de l'Amérique du Nord ont été plantés selon un dispositif complet à blocs randomisés (6 blocs) dans une parcelle nettoyée de 0,7 ha sur l'Ile de Vancouver.Les 24 lots de semis ont été plantés dans chacun des blocs en 1990.La hauteur de la pousse et le nombre de bourgeons avant plantation, le volume spatial (produits de la hauteur du plant par sa largeur sur 2 axes perpendiculaires) en 1992 et 1993, l'accroissement relatif (1992-1993) et le nombre de plants morts en 1992 et 1993 ont fait l'objet d'une analyse de variance.Il n'y a pas de différence significative pour l'accroissement relatif et le Ann.For.

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.
