Resumen
La papaya es una fruta de alta producción y exportación en Colombia, su comercialización se debe al aporte en nutrientes. Sin embargo, su mayor problema de calidad se relaciona con el ablandamiento y la actividad de Poligalacturonasa. Se planteó determinar una posible relación entre los cambios en la actividad enzimática de la Poligalacturonasa, la expresión molecular semicuantitativa de la enzima y los atributos morfoestructurales de las células de papaya como indicadores del avance de la senescencia. Se encontró una relación lineal de expresión génica con actividad enzimática durante el avance de la senescencia. Igualmente se encontró una relación lineal entre factores de tamaño e irregularidad celular con la actividad enzimática y se calculó un modelo aproximativo que describe ese comportamiento.
