It had as objective to evaluate the effect of 8-hydroxyquinoline and chlorine, isolated and mixed in and conservation of the stem stick of the emperor. Twenty of the stem torch ginger (Etlingera elatior), variety Red Torch were harvested, transported, and immersed in standardized solutions containing biocides for 48 hours. The biocide used were 100 mg L -1 of chlorine; 250 mg L -1 of 8-(HQC); 500 mg L -1 of 8-(HQC) and 50 mg L -1 of chlorine + 50 mg L -1 of 8-(HQC), the control corresponded to water. The stems stay immersed in water for nine days at 20 ± 4 ºC. Every 24 hours, the water in the container was replaced. During nine days, some measurements were realized of pH of the water in which the stems stay immersed, in the same way, it was measured the consumption/loss volume of the water for each 24 hours in the containers. The stems were weighed and also samples were taken from the base of the stems and pear ligule determination of peroxidase activity. In general, the use of solutions of 8-(HQC), 250 and 500 mg L -1 , make easier the flux of water in the vases, measured by the consumption of water; provided lower peroxidase activity at the base, independent of the pH of the solution and maintained lower peroxidase activities in the ligule. Thus, with the results obtained, it demonstrated promise the use of 8-(HQC), in the highest concentrations tested (250 and 500 mg L -1 ) for quality maintenance of cut stems of Etlingera elatior, variety Red Torch.

“…Essa espécie destaca-se por seu porte exuberante e formas exóticas de suas grandes inflorescências cerosas com várias colorações, desde branca até o vermelho, incluindo vários tons de rosa. Apresenta características interessantes que levaram vários produtores a comercializá-lo como flor de corte, para composição de arranjos florais e como planta para paisagismo (LOGES, 2008;RIBEIRO et al, 2012).…”

The large ornamental potential of tropical flowers has stimulated the commercial cultivation of various species. Micropropagation is a viable alternate method of propagation, since it enables obtaining a higher number of seedlings with uniformity and pathogens free. The objective was to evaluate the in vitro multiplication rate of Etlingera elatior cv. Porcelana, using explants obtained from in vitro established seedling shoots, obtained from the 2nd subcultive. The explants were inoculated in MS culture medium containing different concentrations of BAP (0.0; 2.22; 4.44; 6.66; 8.88; and 11,10 μM), and the cultures maintained in a growth room with temperature 25.0 ± 2.0 °C under a photoperiod of 12 hours of light and light intensity of 30 μmol.m-2 s-1. The multiplication rate was monthly, according to the four subcultives, totaling 120 days. The experimental design was completely randomized, with four replications, analyzed in a factorial 4 x 6. The data were submitted to analysis of variance and regression. There were significant differences in subcultives and made for BAP concentrations used. For the first subcultive, the concentration of 2.22 μM of BAP afforded a rate of 4.06 sprouts per explant, already in the second and fourth subcultives, with the addition of cytokinin concentration was increased amount of sprouts reaching at a rate of 4.05 and 4.96 shoots/explant in the highest concentration of BAP. The results of the treatments evaluated indicate that the presence of BAP favored sprout emission. The concentrations of 2.22, 8.88 and 11.10 μM this cytokinin promoted the highest multiplication rates in the first, second and fourth subcultives, respectively.

“…The species Etlingera elatior (torch ginger), Zingiber spectabile (ornamental ginger) and Alpinia purpurata belong to Zingiberales order and Zingiberaceae family, originating in Asia (LAMB et al, 2013). The species of this family have favorable characteristics for trade as cut flowers, with atypical shapes and vibrant colors of the flowers of these plants (LOGES et al, 2008).…”

Considering the increase in economical importance of species belong to Zingiberaceae family for floriculture and the advantages of techniques applied to micropropagation of these plants, it is necessary to carry out studies about growth of species in these conditions. The aim of this study was to evaluate the in vitro development of Etlingera elatior, Zingiber spectabile and Alpinia purpurata under different ratios of K, Ca and Mg. The treatments were based on MS medium with K: Mg ratios (mmol L-1) of: 22K:1Mg, 20K:3Mg, 16K:7Mg, 12K:11Mg, 8K:15Mg 4K:19Mg; K:Ca ratios (mmol L-1) of: 22K:4Ca, 20K:6Ca, 16K:10Ca, 12K:14Ca, 8K:16Ca and 4K:22Ca; with five replications, and two seedlings per pot. Explants used were obtained from in vitro rhizomes, kept in a room at a temperature of 25 ± 2°C under irradiance 52W m-2 s-1 and 16 hours photoperiod. After 80 days, seedlings were harvest and have the about number of leaves, height and length of root measured. After, seedlings were separated in shoots and roots, dried and carried out chemical analysis of plant tissue. It is possible to improve the Zingiberaceae plants growth during the micropropagation, changing the concentrations of original formulation MS medium. For K are recommended concentrations of 22 mmol L-1 to Etlingera elatior and Zingiber spectabile cultivation and 16 mmol L-1 for Alpinia purpurata. For Ca, we recommend the concentrations of 4 mmol L-1 for Etlingera elatior and Zingiber spectabile and from 8 to 10 mmol L-1 for Alpinia purpurata. A higher concentration of Mg for in vitro cultivation Etlingera elatior is required. For Zingiber spectabile and Alpinia purpurata it was recommended the proposed merger among MS original concentration of 3 mmol L-1 of this macronutrient.
