The effects of NaCl on a native boreal nitrogen-fixing shrub: Elaeagnus commutata (wolf willow)
Bibliographic record
Abstract
Salinity is a major abiotic stress that reduces the growth and survival of most plants. In Canada, elevated levels of NaCl pose reclamation challenges for habitats disturbed by the oil sand industry. I examined the salt tolerance of Elaeagnus commutata (wolf willow), a native nitrogen fixing boreal shrub that has potential for land reclamation, by conducting greenhouse hydroponics experiments with seedlings (uninoculated or inoculated with Frankia), exposed to 0,50 and 100 mM NaCl for 12 weeks. All plants survived 100 mM NaCl, suggesting that E.commutata is a moderately salt tolerant plant. Despite reductions in performance of salt stressed seedlings, they were still able to maintain relatively high levels of physiological activities and shoot/root growth. Plant mostly maintained nutritional balance even with elevated levels of Na+ and Cl- in their tissues. However, salinity inhibited root nodule formation and severely reduced root nitrogen fixation. To confirm the suitability of E. commutata as a potential species for saline land reclamation, field studies should be conducted.

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.
