Effects of Simulated Salt and Alkali Interaction Stress on the Germination and Seedlings Growth at Germination Stage of Sorghum bicolor × S. sudanense Seeds
Bibliographic record
Abstract
To determine the dominant factors limiting the germination and seedlings growth at germination stage of Sorghum bicolor × S. sudanense seeds in saline- alkali soil,two kinds of neutral salts( NaCl,Na2SO4) and two kinds of alkaline salts( NaHCO3,Na2CO3) were mixed in different proportions,the authors simulated 16 salt and alkali interaction stresses,and studied the effect of salt and alkali interaction stress on the germination and seedlings growth at germination stage of Sorghum bicolor × S. sudanense seeds. The results showed that total salt concentration,pH and the concentration of CO2-3and HCO-3had great influence on the germination and seedlings growth at germination stage of Sorghum bicolor × S. sudanense seeds,and the concentration of CO2-3and HCO-3were the main factors influencing the pH value,so the total salt concentration and pH value could be assumed to be the dominant factors limiting the germination and seedlings growth at germination stage of Sorghum bicolor × S. sudanense seeds. However,germination parameters( Gr),germination potential( GP),germination index( Gi) and other indicators which reflect the germination rate of seeds and germinal length( GL),root length( RL),lateral root number( LRN) and other indicators which reflect seedlings growth parameters had different sensitivity to salt concentration and pH stress. Under the same salt concentration,the reduction of GL,RL and LRN was more obvious than that of Gr,GP and Giwith the increase of pH value,there is also significant difference between the salt damage coefficient,it showed that salt concentration had great influence on the germination of Sorghum bicolor × S. sudanense seeds,and the high pH stress mainly affected the seedlings growth. Therefore,the process of Sorghum bicolor × S. sudanense planting in saline- alkali soil should consider both the factor of soil salinity and the pH value.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
