| description | Chlorophyll fluorescence is used to characterize the plant response to natural environments or under stress conditions. This study aimed to identify correlations between the maximum quantum efficiency of PSII (Qy) with climatic and soil variables associated with bunch weight. The experimental design used in the field corresponds to an observational and longitudinal study, where 72 production units in the independent vegetative stage were randomly selected, of which 36 units from a low production area and 36 from a high production area. In each unit, the quantum yield (Qy: Fv/Fm) was measured and correlated with climatic and soil variables, the nutrient content in the leaves, and the average weight of the cluster in each sampled batches. The results indicated a correlation between Qy of -0.703 concerning temperature and -0.583 with radiation. On the other hand, pH and resistance to soil penetration are directly related to Qy to a lesser extent, with r2 values of 12.77 and 24.28%, respectively. Precipitation, wind, gusts, dew point, atmospheric pressure, and texture composition of the soil do not significantly affect Qy variation; when attacks of leaf pests (mites) occur, significant reductions are also observed in this. Qy is a variable that responds to the stress generated by factors external to the plant, these can significantly affect production, and which is reduced by up to two kg per cluster, with a bias of three to four weeks, when the loss of 0.04 points in the value of Qy occurs. |

La fluorescencia de la clorofila es empleada para caracterizar la respuesta de los vegetales a ambientes naturales o bajo condiciones de estrés. El objetivo de este estudio fue identificar correlaciones entre la máxima eficiencia cuántica de PSII (Qy) con variables climáticas y edáficas asociadas al peso del racimo. Se empleo un diseño experimental de tipo observacional y longitudinal, donde se seleccionaron al azar 72 unidades productivas en etapa vegetativa independiente, 36 en un lote de baja producción y 36 en un lote de alta producción, a cada una de las cuales se le midió el rendimiento cuántico (Qy: Fv/Fm) del fotosistema II, y se correlacionó con variables climáticas y edáficas, con el contenido de nutrientes en las hojas y con el peso promedio del racimo en cada uno de los lotes muestreados. Los resultados indicaron una correlación entre Qy de -0,703 con respecto a la temperatura y -0,583 con la radiación. Por otro lado, el pH y la resistencia a la penetración del suelo se relacionaron de forma directa con Qy en menor proporción con valores de r2 de 12,77 y 24,28%, respectivamente. La precipitación, el viento y sus rachas, el punto de rocío, la presión atmosférica y la composición textural del suelo no afectaron de forma significativa la variación Qy. Cuando se produjeron ataques de plagas en hojas (ácaros), también se observaron reducciones significativas en Qy. Qy es una variable que responde al estrés generado por factores externos a la planta, estos pueden afectar significativamente la producción, la cual se reduce hasta en dos kg por racimo, con un sesgo de tres a cuatro semanas, al presentarse la pérdida de 0,04 puntos en el valor de Qy.
