| description | The global demand for avocados has grown in recent years. In Colombia, the Lorena variety is widely accepted in the market but the challenge for consumers is determining when the fruits should be consumed. However, there are no studies on this matter because most research is done on the Hass variety, which dominates global production. Therefore, the objective was to evaluate ripening treatments in Lorena variety avocado fruits to establish the postharvest behavior, avoid quality losses, and maintain organoleptic characteristics, facilitating commercialization of the product. A randomized complete block design was used with two blocks (maturity I and maturity II), five maturation treatments, three ethylene applications (2, 4 and 6 mL L-1), fruits wrapped in unprinted newspaper, and a control. The fruits reached 16 days after harvest (dah) with commercial quality. The application of 6 mL L-1 of ethylene presented the greatest mass loss. At 6 dah, the climacteric peak presented with the highest values of soluble solids, maturity index (MI), and loss of firmness and the lowest percentage of total titratable acidity (TTA). The TTA had higher values for the control treatment during storage. The MI registered two maximums during postharvest: the first in the climacteric peak, and the second during fruit senescence. |

In Colombia, the Lorena variety is widely accepted in the market but the challenge for consumers is determining when the fruits should be consumed. However, there are no studies on this matter because most research is done on the Hass variety, which dominates global production.

The TTA had higher values for the control treatment during storage. The MI registered two maximums during postharvest: the first in the climacteric peak, and the second during fruit senescence. La demanda por el fruto de aguacate en el mundo ha crecido en los últimos años. En Colombia, un cultivar que tiene una amplia aceptación en el mercado es la variedad Lorena, la cual tiene frutos que generan dificultad en los consumidores a la hora de identificar el momento adecuado de consumo, sin que haya estudios al respecto, debido a que la mayoría de investigación se realiza en la variedad Hass cuya producción es dominante en el mundo. Por lo anterior, el objetivo fue establecer tratamientos de maduración en frutos de aguacate variedad Lorena, con el fin de conocer el comportamiento poscosecha, para evitar pérdidas de calidad y mantener las características organolépticas, facilitando la comercialización del producto. Para lo cual, se llevó a cabo un diseño de bloques completos al azar, con dos bloques (madurez I y madurez II) y cinco tratamientos de maduración así: tres aplicaciones de etileno (2, 4 y 6 mL L-1), frutos envueltos en papel periódico sin imprimir y un testigo. Los frutos alcanzaron 16 días después de cosecha (ddc) con calidad comercial. La aplicación de 6 mL L-1 de etileno presentó la mayor pérdida de masa. A los 6 ddc se presentó el pico climatérico con los mayores valores de sólidos solubles, índice de madurez (IM) y pérdida de firmeza y los más bajos porcentajes de acidez total titulable (ATT). La ATT mostró mayores valores para el tratamiento testigo durante el almacenamiento. El IM registró dos máximos durante la poscosecha, el primero en el pico climatérico y el segundo durante la senescencia del fruto.
