Effects of plant growth-promoting rhizobacteria on the seedling growth of oat and annual ryegrass at various salt concentrations
Bibliographic record
Abstract
Four strains of plant growth-promoting rhizobacteria(PGPR) containing 1-aminocyclopropane-l-carboxylic acid(ACC) deaminase were isolated from the rhizosphere of salty plants,and their effects on the seedling growth of oat and annual ryegrass at various salt concentrations in gnotobiotic growth pouch assay were investigated.These four bacterial isolates,especially Pseudomonas sp.S1,alleviated greatly salt stress and promoted significantly the seedling growth of oat and annual ryegrass under either 5 g/kg or 10 g/kg NaCl stress. Compared with control(no NaCl),more plant promotion was observed under 10 g/kg NaCl stress.The greatly significant positive correlations between ACC deaminase activity of four bacterial isolates and plant growth parameters(root length and shoot length) were observed(Pearson correlation co-efficients0.81).

How this classification was reachedexpand
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.
