Variation of Sodium Uptake Rate in Suaeda glauca and Its Relation to Plant Size and Salt Acclimation
Bibliographic record
Abstract
To characterize the pattern of sodium uptake by Suaeda glauca (Bunge) plants at mild salinity, this study investigated the temporal variation of sodium uptake rate (mmol Na+ plant−1 d−1) and its relation to plant size (i.e., main stem length) and salt acclimation for S. glauca grown in nutrient solutions with 6, 8, or 10 mM NaCl. During the 23-d salt treatment, sodium uptake rate in S. glauca increased gradually at 5- to 7-d intervals with time advancement and showed a positive exponential relationship with the development of plant size. During the first week (0–7 d) of salt treatment, the weekly average sodium uptake rate was higher in larger plants than in smaller ones. During the last week (18–23 d) of salt treatment, non-salt-acclimated plants showed a similar sodium uptake rate (on a weekly average) to salt-acclimated plants when their plant sizes were not significantly different. These results suggest that at the largest plant size (i.e., 1 wk before harvesting as a leafy vegetable), S. glauca reached the maximum level of sodium uptake rate, which was affected to a larger degree by plant size than by salt acclimation on a weekly scale.

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.
