Estimación del área foliar del arándano (Vaccinium corymbosum) por medio de un método no destructivo

Abstract

Se llevó a cabo una investigación para estimar un modelo de medición no destructiva de área foliar en plantas de arándano (Vaccinium corymbosum), en condiciones de trópico alto, mediante análisis secuencial de regresión, a partir de mediciones lineales de ancho de lámina foliar (Ah), longitud foliar (Lh) y el producto de la longitud por el ancho (LxA). Se utilizaron plantas de las variedades Sharp Blue y Biloxi para desarrollar los modelos en las localidades de Sibaté y de Firavitoba. El proceso de calibración fue desarrollo con las plantas sembradas en Sibaté, con 180 observaciones y, la validación de modelos, se efectuó en un huerto de Firavitoba. Se obtuvieron seis modelos, tres lineales y tres de forma polinómica de segundo orden, para cada material genético. Las formas seleccionadas fueron: AF = 0,638(LxA), R2 0,94 y AF = 0,0075(LxA)2 + 0,3321(LxA) + 2,2104, R2 0,94. Estos modelos fueron validados por nuevas muestras de hojas obtenidas de diferentes partes del dosel vegetal (bajo, medio y superior), solamente en plantas de la variedad Sharp Blue. Los modelos de la variedad Biloxi presentaron R2 muy bajos y alto CME. Los modelos, producidos en este estudio, se pueden utilizar de forma confiable para calcular el área individual de la hoja de distintos niveles foliares del dosel vegetal para la variedad de arándano Sharp Blue y, de esta forma, determinar el área foliar por planta sin necesidad de realizar muestreo destructivo. Esto no se puede aplicar para el cultivar Biloxi.
