In vitro Bioassay of Allelopathic Activities of Soybean, and Three Isoflavones, Using Protoplast Co-culture Method with Digital Image Analysis
Bibliographic record
Abstract
Inhibitory allelopathic activities of dried leaves of potted plants and protoplasts of Glycine max (soybean) cv. Okuhara-wase were studied using two in vitro bioassay methods. Strong inhibition (90%) of growth of recipient lettuce root was obtained with 50 mg soybean leaves using the lettuce seedling growth test (sandwich method), and moderate inhibition (65%) of lettuce protoplast division was obtained with 100 × 103 mL-1 protoplasts of etiolated soybean seedlings using the protoplast co-culture method with digital image analysis (DIA-PP method). Three isoflavones, genistein, genistin (genistein-7-O-glucoside), and daidzin (daidzein-7-O-glucoside) were investigated as putative allelochemicals using the DIA-PP method. The three isoflavones at 100 µM showed early crystal accumulation in lettuce protoplasts and inhibited lettuce protoplast division by 100%. Genistein showed the strongest inhibition. The results were compared and discussed with the previous reports on the invader leguminous plant, Kudzu, and two isoflavones, daidzein and Kudzu-specific puerarin (daidzein-6-C-glucoside), and other allelopathic plants and their putative allelochemicals.

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.
