Study on Allelopathy of Aqueous Extract from Three Crops on Codonopsis pilosula
Bibliographic record
Abstract
The allelopathy effects of wheat straw,horsebean straw and flax straw on Codonopsis pilosual were studied by bioassay methods.The results showed that the aqueous extracts of three crops straw could inhibit the seed germination of Codonopsis pilosual,compared with the controlled,0.15g/ml concentration of inhibitory effect was significantly,0.05g/ml concentration of inhibitory effect was not obvious.On the all test concentration,the inhibitory effect of horsebean aqueous extracts was lower than that of wheat and flex.The root length and dry matter accumulation of Codonopsis pilosula had the effect of low-stimulating and high-inhibitory of horsebean and flex straw extracts,and the best promoting effect was 0.05g/ml concentration of straw extracts.The root length and shoot length of Codonopsis pilosula was restrained by wheat straw extracts,but the effect of dry matter accumulation of leavies and roots of Codonopsis pilosual was promoted by wheat straw extracts significantly,and was 2.11times and 1.32 times of the controlled respectively.

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.
