Hydration with citric acid or benzyladenine improves the metabolism and quality of tuberose

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.SourcesHydrating solutions in two tuberose (Polianthes tuberose) cultivars: physical, physiological?and biochemical responsesSandy Lizbeth Fernando-Santos, Gloria Alicia P?rez-Arias, Iran Alia-Tejacal, Clara Pelayo Zald?var, V?ctor L?pezMart?nez, Porfirio Ju?rez-L?pez &?Dagoberto S?nchez-Guill?nBiotecnia, Revista de Ciencias Biol?gicas y de la Salud Volumen XXIII, N?mero 1, http://biotecnia.unison.mx Picture https://gardenseedsmarket.com/
