Generalmente los trabajos reportados en esta especie se centran en el genotipo virens levis, pero existe muy poca información del comportamiento poscosecha del genotipo n. spinosum bajo almacenamiento refrigerado. Para ello se cosecharon frutos en madurez hortícola y se almacenaron a temperatura ambiente (20 ±2 °C) y a baja temperatura (10 ±1 °C, 85% HR) durante tres periodos de tiempo (3, 6 y 9 semanas) con y sin la aplicación de 1-metilciclopropeno (0, 500 y 1 000 nL L-1) para reducir el viviparismo. Las variables evaluadas fueron: porcentaje de humedad, acidez titulable, SST (ºBrix), contenido de clorofila a y b y total, contenido de azúcares totales (sacarosa, fructosa y glucosa), pérdida de peso y porcentaje de viviparismo. Los resultados mostraron un contenido promedio de humedad de 94%, con bajo contenido de SST (4.5-5.2%) que permanece sin cambios durante el almacenamiento, un contenido de fructosa y glucosa de 1.07% y 0.89% respectivamente, sin la presencia de sacarosa. Los frutos mantuvieron sus características de apariencia con el almacenamiento refrigerado por 3 semanas, pero a 6 y 9 semanas, fue evidente la deshidratación de espinas, aunque ambas dosis de 1-MCP (500 y 1000 nL L-1) redujeron significativamente el viviparismo, incrementaron la susceptibilidad a la incidencia de hongos principalmente Fusarium sp.]]></p></abstract>

Generally, the works reported in this species are focused on the genus virens levis, but there is very little information on the post-harvest behavior of genotype n. spinosum under refrigerated storage. For this, fruits were harvested in horticultural maturity and stored at room temperature (20 ±2 °C) and at low temperature (10 ±1 °C, 85% RH) for three periods of time (3, 6 and 9 weeks) with and without the application of 1-methylcyclopropene (0, 500 and 1 000 nL L-1) to reduce viviparism. The variables evaluated were humidity percentage, titratable acidity, SST (ºBrix), chlorophyll a and b content and total, content of total sugars (sucrose, fructose and glucose), weight loss and percentage of viviparism. The results showed an average moisture content of 94%, with low SST content (4.5-5.2%) that remains unchanged during storage, a fructose and glucose content of 1.07% and 0.89% respectively, without the presence of sucrose. The fruits maintained their appearance characteristics with refrigerated storage for 3 weeks, but at 6 and 9 weeks, the dehydration of thorns was evident, although both doses of 1-MCP (500 and 1000 nL L-1) significantly reduced the viviparism, increased the susceptibility to the incidence of fungi mainly Fusarium sp.]]></p></abstract>
