description	Blueberries in the Ericaceae family are important, cultivable species for commercial and industrial purposes. Critical parameters for evaluating the nutritional and physiological status of plants include estimates of photosynthetic pigments such as chlorophylls; however, this is a destructive, expensive and time-consuming method that is not easily accessible for agricultural producers. For this reason, in recent years, several technological solutions have been made available, such as the SPAD-502 chlorophyll index meter, which has demonstrated efficiency in terms of rapid estimates of total chlorophyll content in the field. Therefore, the objective of this research was to evaluate the contents of chlorophylls a, b and total obtained with spectrophotometry and to determine the correlation with the non-destructive method (SPAD) in blueberry plant (Vaccinium corymbosum L.) cultivares Biloxi, Legacy and Victoria, in the vegetative phase under conditions of the municipality of Paipa-Boyaca (Colombia). The data obtained with the SPAD-502 ranged from 57.4 to 62.8 SPAD in the 'Victoria', 61.2 to 68.3 in the 'Biloxi', and 68.2 to 73.1 in the 'Legacy'. The content of chlorophylls a, b and total presented a positive and significant correlation with the SPAD index, with a correlation coefficient (r) greater than 0.91 and adjustment to simple linear regression models with a coefficient of determination (R2) greater than 0.90 in the three cultivars. This confirms the usefulness and importance of using SPAD for non-destructive estimation of chlorophyll content under field conditions.

Los blueberry dentro de la familia Ericaceae, son especies cultivables importantes con fines comerciales e industriales. Dentro de los parámetros críticos para evaluar el estatus nutricional y fisiológico de la planta, es la estimación de pigmentos fotosintéticos como las clorofilas; sin embargo, este es un método destructivo, costo y demorado, al cual no pueden acceder fácilmente los productores agrícolas. Por esto en los últimos años, se han puesto a disposición varias soluciones tecnológicas, tales como el medidor de índice de clorofila SPAD-502 el cual ha demostrado su eficiencia en cuanto a la estimación rápida de los contenidos totales de clorofila en campo. Por lo anterior, el objetivo de la investigación fue evaluar los contenidos de clorofilas a, b y total obtenidas mediante espectrofotometría y su correlación frente al método no destructivo (SPAD) en plantas de blueberry (Vaccinium corymbosum L.) de los cultivares Biloxi, Legacy y Victoria, en fase vegetativa bajo condiciones del municipio de Paipa-Boyacá (Colombia). Los datos obtenidos con el SPAD-502 oscilaron entre 57,4 a 62,8 SPAD en la 'Victoria', 61,2 a 68,3 en la 'Biloxi' y 68,2 a 73,1 SPAD en la 'Legacy', el contenido de clorofilas a, b y total, presentaron una correlación positiva y significativa frente al índice SPAD con coeficiente de correlación (r) mayor a 0,91 y el ajuste a modelos de regresión lineal simple con coeficiente de determinación (R2) superior a 0,90 en las tres cultivares evaluadas. Esto confirma la utilidad e importancia de usar el SPAD para la estimación no destructiva del contenido de clorofilas bajo condiciones de campo.
