Abstract

fetched live from OpenAlex

Se realizó un ensayo en invernadero, con el objetivo de determinar la eficiencia simbiótica de 39 cepas nativas de bradyrizobios procedentes de Sancti Spíritus. Los aislamientos se hicieron a partir de nódulos radicales de Centrosema molle, Centrosema virginianum y Centrosema plumieri, los cuales son macrosimbiontes provenientes de las zonas centro y sur de Sancti Spíritus. Las cepas obtenidas se inocularon en C. molle, leguminosa forrajera promisoria para la alimentación del ganado en el territorio. Los métodos de inoculación fueron estándares, acorde con lo recomendado en la literatura internacional. El diseño experimental fue de bloques al azar, con 41 tratamientos y tres réplicas. Se realizó análisis de varianza (ANOVA) y se evaluó el peso seco de la parte aérea de la planta, el peso seco radical, el índice de nodulación y el rendimiento de nitrógeno. Se concluye que existió una alta eficiencia simbiótica de las cepas nativas de la zona centro, al ser inoculadas en una leguminosa perteneciente a la misma zona; mientras que las de la zona sur fueron ineficientes en dicha leguminosa. Por otra parte, JK3 (C. virginianum), HG1 (C. plumieri) ambas de la zona centro, SP20 (C. molle, zona sur) y JJ2 (C. virginianum, zona centro) presentaron altos índices de eficiencia en la leguminosa evaluada, lo que las convierte en las más promisorias. Los altos índices de nodulación de JH4, JJ2, JJ7, JK6, JK1 y JK5 (C. virginianum) no implicaron una alta eficiencia simbiótica. Se recomienda una fase de selección en condiciones de campo, con diferentes macrosimbiontes y en condiciones edafoclimáticas estresantes.

Not 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.
