Study on Identification of Seedborne Fusarium species of Rootstock for Watermelon Grafting and Their Pathogenicity
Bibliographic record
Abstract
Two Fusarium isolates were obtained from seed embryo and seed coat of rootstock seeds(cvs.Shenlizhenmu and Futianjiangjunzhenmu) for watermelon grafting,repectively.The two isolates were identified using morphological methods and DNA sequencing analysis.Effects on seed germination and pathogenicity to seedlings of these two Fusarium isolates were also determined.The results showed that the two Fusarium strains were identified to be Fusarium oxysporum.They had significant effect on seed germination,compared to control treatment,which causing reduction of germination energy,percentage germination,germination index and vigor index significantly;they were pathogenic to rootstock seedlings and caused typical wilt symptom on leaves,fulfilled Koch’s postulates.To our knowledge,it’s the first report of seedborne F.oxysporum of rootstock for watermelon grafting can be pathogenic to rootstock seedlings in China.

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.
