Abstract
Objective: The objectives were to research the response of Glycyrrhiza uralensis on morphology and structure under different salt stress environment. Methods: Taking Glycyrrhiza uralensis Fisch as materials. By the method of hydroponics,seedlings were cultured in plastic pots filled with a complete Hoagland nutrient solution with different concentration of Na HCO3,Na Cl and Na2SO4. After 30 days,we measured the plant height,root length,root biomass,total biomass and leaf area. We determined the leaf thickness,stomatal density and gland density by technology of paraffin section and scanning electron microscopy. Result: There were different growth inhibition of Glycyrrhiza uralensis under three kinds of salt stress. The damage strength of salt stress was Na HCO3 Na Cl Na2SO4. With the increasing of Na2SO4 concentration,the root biomass and total biomass were highly significant increased. Middle concentration of Na2SO4 had promoted the plant height and root length increased. High concentration of Na2SO4 make the layers of palisade tissue cell increased,so the leaf thickness and specific leaf weight were increased. The total biomass was significantly less than the control group under the middle and low concentration of Na Cl,but did not significantly influenced the root biomass.High concentration of Na Cl treatment promoted the root length and root biomass accumulation,so that the total biomass significantly increased. Under Na Cl treatment,the leaf area and leaf thickness significantly decreased.There were no plants survived under high concentration of Na HCO3treatment( 50 mmol / L),but low Na HCO3treatment( ≤50 mmol / L) were conducive to root biomass and total biomass accumulation. The 25 mmol / L Na HCO3 treatment significantly inhibited the leaf area increased,so the leaf thickness and leaf weight ratio were increased. Three kinds of single salt stress could promoted the differentiation of leaf stomata,but inhibited the leaf glandular growth.

Full frame distilled prediction
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
