Hydrating solutions in two tuberose (Polianthes tuberose) cultivars: physical, physiological and biochemical responses
Tuberose (Polianthes tuberosa) ‘Mexicano’ and ‘Perla’ spikes, were harvested with 5 or 1 open basal flowers, and then treated with hydrating solutions containing gibberellic acid, benzyladenine, amino oxyacetic acid, citric acid, sucrose or hydroxyquinoline citrate, to evaluate postharvest physical,...

Nardo, peroxidasa, catalasa, superóxido dismutasa, respiración. Tuberose (Polianthes tuberosa) ‘Mexicano’ and ‘Perla’ spikes, were harvested with 5 or 1 open basal flowers, and then treated with hydrating solutions containing gibberellic acid, benzyladenine, amino oxyacetic acid, citric acid, sucrose or hydroxyquinoline citrate, to evaluate postharvest physical, chemical and physiological changes, for a later technological development to increase the useful life of this ornamental plant. We used a radomentized experimental design, with a spike as the experimental unit and six or eight repetitions. Our results indicate that in both varieties, the relative fresh weight and water consumption and the number of open flowers increased, while respiration and total sugars decreased, when treated with HS containing AC or BA. The appearance was good for five days in ‘Mexicano’ spikes hydrated with AC or BA + Sac, while in ‘Perla’, for seven days in all HS-applied treatments. Peroxidase, catalase and superoxide dismutase enzymatic activities were high in control spikes and low when hydrated with AC or BA. In conclusion, hydration with AC or BA improves the metabolism and quality of ‘Mexicano’ and ‘Perla’ spikes. Espigas de nardo (Polianthes tuberosa) ‘Mexicano’ y ‘Perla’ con 5 ó 1 flores basales abiertas, se trataron con soluciones hidratantes (SH) conteniendo ácido gibérelico (AG3), benciladenina (BA), ácido amino-oxiácetico (AOA), ácido cítrico (AC), sacarosa (Sac) o hidroxiquínoleina citrato (HQC) con el objetivo de evaluar los cambios físicos, químicos y fisiológicos durante poscosecha, para posteriormente desarrollar tecnologías que incrementen la vida útil de esta especie ornamental. Se utilizó un experimento completamente al azar, la unidad experimental fue una espiga con seis a ocho repeticiones. Los resultados indican que el peso fresco relativo, consumo de agua y número de flores abiertas se incrementó; la respiración y azúcares totales disminuyeron en ambas variedades, cuando se aplicaron SH con AC o BA. La apariencia fue buena por cinco días en ‘Mexicano’ en las espigas hidratadas con AC o BA+ Sac y en ‘Perla’ por siete días en todos los tratamientos donde se aplicó SH. La actividad de peroxidasa, catalasa y superóxido dismutasa fue mayor en las espigas testigo y menor cuando se aplicaron las SH con BA + Sac o AC. En conclusión, la hidratación con AC ó BA mejoran el metabolismo y calidad de las espigas de nardo ‘Mexicano’ y ‘Perla’ en poscosecha.
