Abstract
Hangs, R. D., Schoenau, J. J., Van Rees, K. C. J. and Steppuhn, H. 2011. Examining the salt tolerance of willow (Salix spp.) bioenergy species for use on salt-affected agricultural lands. Can. J. Plant Sci. 91: 509-517. Dryland salinity is a significant limitation on crop production across the Canadian prairies, with an estimated 4 million ha of salt-affected land. The potential exists to make better use of saline marginal lands by developing them into willow (Salix spp.) plantations as a bioenergy feedstock; however, relatively little is known about the salt tolerance of willow. The objective of this study was to compare the relative salt tolerance of 37 different native and exotic willow varieties grown under controlled environment conditions on soils of varying salinity. The soils were collected from a farm field in south-central Saskatchewan along a hillslope catena influenced by saline seep salinity, containing high concentrations of sulfate salts, which commonly occurs within western Canada. Most willow varieties tested in this study were able to tolerate moderately saline conditions (ECe=5.0 dS m-1). In addition, several varieties (Alpha, India, Owasco, Tully Champion, and 01X-268-015) showed no reduction in growth with severe salinity (ECe=8.0 dS m-1). These results indicate that some willow varieties are quite salt-tolerant and suitable for establishment on salt-affected soils in Saskatchewan and abroad.

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 it
