Abstract
The effects of magnetized water irrigation on the growth and ionic movements of one-year-old potted seedlings of Populus × euramericana ‘Neva’ were investigated. A magnetic treatment device was used to treat the plants. The contents of K + , Na + , Ca 2+ , and Mg 2+ in leaves and roots were analyzed by atomic absorption spectrophotometry (AAS), and the fluxes of K + , Na + , Ca 2+ , Mg 2+ , and H + in mesophyll cells and in meristematic zones were measured using a noninvasive micro-test technique (NIMT) after 30 days of treatment. After 90 days, the plants were harvested, and their growth indices and root morphology were measured. The results showed that (i) compared with nonmagnetic treatments (NMT), the magnetic treatments (MT) led to higher K + and Mg 2+ contents and lower Ca 2+ content in roots and leaves, while the Na + content was lower and the K + /Na + ratio was higher; (ii) MT enhanced Na + efflux, increased H + influx, and decreased K + and Mg 2+ efflux compared with NMT; (iii) MT resulted in greater height, diameter, and leaf area of the plants and increased the length, surface area, and number of root tips compared with NMT; and (iv) stomatal conductance (Gs), net photosynthetic rate (Pn), intercellular CO 2 concentration (Ci), and water use efficiency (WUE) were increased in MT, whereas both transpiration rate (Tr) and stomatal limiting value (Ls) were decreased compared with NMT. The results indicate that the use of magnetized water can promote plant quality and regulate the ion absorption, transpiration, and distribution. Thus, MT is conducive to the re-establishment of ionic homeostatic mechanisms via ion-selective absorption and transportation under salt stress.

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
