Morfologia, valor nutritivo e anatomia de Brachiaria brizantha sob doses de fósforo e idades de corte
Bibliographic record
Abstract
Objetivando avaliar o efeito de doses de fósforo e idades de corte na morfologia e valor nutritivo de folhas de B. brizantha Stapf cv. Marandu e correlacionar características anatômicas com o valor nutritivo, foi conduzido um experimento inteiramente casualizado com 4 repetições, em esquema fatorial 3 x 5, sendo 3 idades de corte (28, 56 e 84 dias) e 5 doses de P (20, 200, 400, 600 e 800 mg.dm-3). O capim-marandu foi cultivado em vasos de 4 dm3. Foram medidas as características morfológicas. E confeccionadas lâminas das folhas e as secções fotomicrografadas foram as áreas do esclerênquima (ESC), da bainha parenquimática dos feixes (BPF), do metaxilema (MET), do floema, das células buliformes, espessura do mesofilo (MES), das epidermes e a distância entre feixes. Determinou-se a produção de MS, e os teores de proteína bruta (PB), fibra em detergente neutro (FDN), fibra em detergente ácido (FDA), lignina, a digestibilidade in vitro da matéria seca (DIVMS). O aumento nas doses de P e idades de corte proporcionou aumento na MS e redução na DIVMS e PB. Houve correlações positivas entre o MET e FDA; mesofilo, células buliformes e BPF com a DIVMS e PB; e foram negativas entre floema, MET e ESC e PB.

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.
