New Reports of Fungi on Mahogany (Swietenia macrophylla King, Meliaceae) Leaves and Seeds in Brazil
Bibliographic record
Abstract
Mahogany (Swietenia macrophylla King, Meliaceae) is a forest species of high commercial value and is considered noble in many countries. Fungi are the main plant pathology agents, and can attack roots, leaves, flowers, fruits, woods, and seeds. Studies on diseases caused by fungi that affect S. macrophylla are incipient. There is little information about foliar diseases and pathogens that are transmitted by seeds. Because of the scarcity of this type of study in the above referenced species, this study aimed to identify and characterize the fungi found in leaves and seeds of mahogany collected in a small urban forest located in Brasilia, Federal District, Brazil, as well as to evaluate the pathogenicity of potentially pathogenic fungi. In our study, a foliar fungus, not yet reported for mahogany in Brazil, was found, Phomopsis sp. In seeds, this paper represents the first report of the occurrence of Fusarium oxysporum causing reduction in seed germination and death of mahogany seedlings. In addition, the fungi Aspergillus, Curvularia, Penicillium and Rhizopus also were found on mahogany seeds.

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.
