Abstract

fetched live from OpenAlex

El objetivo fue determinar, durante dos años, el contenido de β-caroteno y su relación con el Índice de Color (IC), de ocho cultivares comerciales del tipo 'Flakkee' cultivadas en el INTA La Consulta. El diseño experimental a campo utilizado fue en bloques al azar con 3 repeticiones. Se evaluó β-caroteno (espectrofotometría a 450 nm) y se calculó el IC, mediante captación de imagen digital con PC y escáner, midiendo L, a y b del Sistema CIELAB. Los datos fueron analizados por ACP (análisis de componentes principales), la visualización de la variabilidad, por cartografiado de datos, análisis de varianza, pruebas de diferencia de medias y correlaciones. Los contenidos de β-carotenos y el IC de los cultivares se mantuvieron constantes durante los dos años estudiados, resultando las cultivares Natasha, Flakesse y Colmar las de mayor valor nutricional en cuanto a aporte de β-carotenos. En el rango de valores menores de 18 mg%g de β-carotenos, se observó una correlación positiva significativa en las cultivares Supreme, Spring y Laval. No se encontró una correlación alta lineal entre el IC y el contenido de β-carotenos. El uso del IC resulta adecuado para predecir, en un intervalo de valores, el contenido de β-carotenos en cultivares de zanahoria.

Full frame distilled prediction

Teacher imitation

Not 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.
