Effects of Saline-Alkali Stress on Seed Germination and Seedling Growth of Wild Wancomponents(Kochia scoparia(L.) Schrad)
Bibliographic record
Abstract
The seeds of wild wancomponents(Kochia scoparia(L) Schrad) were tested under 30 kinds of mixed salt solutions composed of NaCl,Na2SO4,NaHCO3,Na2CO3 at different proportions of salinity and alkalinity similar to natural saline-alkali soil.Seven indexes such as germination rate were determined.The results showed that the germination capability of wild wancomponents seeds was restrained obviously under complex saline-alkali stress.Complex saline-alkali stress decreased germination rate,germination energy and germination index.With saline-alkali concentration increasing,the trend became more obvious.The mixed effect of high saline-alkali stress was much stronger than that of high salt stress or high alkali stress respectively.The survival rate and relative water content decreased among all the six different treated groups,but MDA and soluble sugar content increased gradually with saline-alkali degree increasing,and increasing range of soluble sugar under 50,100 mmol/L or low pH was lower than 200,250 mmol/L or high pH.So it played obvious cooperation role between saline and alkali stress.

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.
