Optimum Harvest Time of Cucumis africanus Fruit Using Concentration of Cucurbitacin B as a Maturity Standard
Bibliographic record
Abstract
Fruit of wild watermelon (Cucumis africanus) are used to manufacture nemafric-BL phytonematicide for the management of population densities of the notorious root-knot (Meloidogyne species) nematodes on various crops. However, the concentration of the active ingredient, namely, cucurbitacin B, is dependent on the developmental stage of the fruit. A field study was, therefore, conducted to establish the optimum harvest time where C. africanus fruit would have the highest concentration of cucurbitacin B in order to ensure consistent quality of the phytonematicide. Fruit were harvested weekly from 60 to 110 days after transplating, prepared for extraction and cucurbitacin B quantified using reverse phase HPLC. Concentrations of cucurbitacin B were optimised at 5.0 weeks, which translated to a 95-day harvest time after seeding.

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.
