Preservative postharvest solutions in two varieties of tuberose (Polianthes tuberosa L.) native to Mexico: ‘Mexicano’ and ‘Perla’

ntroduction: ‘Perla’ and ‘Mexicano’ are varieties of tuberose grown in Mexico that have potential for commercialization export; however, no preservative solutions been evaluated to increase their shelf life. Objective: To determine physical, physiological, chemical changes occur postharvest when different applied. Methodology: Tuberose flower spikes Perla, with two open basal flowers, were placed (Crystal®, sucrose [Sac] + citric acid [CA] hydroxyquinoline citrate [HQC] ascorbic [AAsc]). A group was kept as control, all cases destructive non-destructive variables during postharvest. Results: Relative fresh weight water consumption increased both varieties. The appearance the variety excellent 5 days Crystal®. had more flowers Crystal® Sac AC HQC, while same result AAsc Respiration Mexicano’ high case variety, respiration low AAsc. highest specific superoxide dismutase activity detected variety. Study limitations: results valid without previous applications pulse or hydrating evaluated. Originality: This is first study where behavior Mexican solutions. Conclusions: can use maintain quality longer time vase.
