Allelopathic Potential of Hesperozygis ringens Extracts on Seed Germination of Soybeans and Beggarticks
Bibliographic record
Abstract
Hesperozygis ringens L., popularly known as espanta-pulga, is a native shrub found in rocky fields in Rio Grande do Sul. Its leaves produce a lot of essential oil, which contains pulegone as a main component that may be allelopathic. The objectives of this study were to analyze the allelopathic effects of H. ringens leaf extracts on the germination and initial development of soybean seeds and to evaluate the herbicidal potential of these extracts on beggarticks (Bidens pilosa L.). The seeds were placed on paper embedded in an aqueous extract of H. ringens leaves at concentrations of 0, 25, 50, 75 and 100% and maintained in a germination chamber at 25 °C and a photoperiod of 12 h. The tests included the following: germination, first germination count, germination speed index, and length and dry mass of seedlings. The experimental design was completely randomized. Based on the results, the aqueous extracts of Hesperozygis ringens leaves had a detrimental effect on the germination and seedling growth of the soybeans and beggarticks, evidencing their allelopathic action.

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.
