Resumo: | 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. |

Diante do exposto, o objetivo do trabalho foi avaliar o desenvolvimento in vitro de espécies Etlingera elatior, Zingiber spectabile e Alpinia purpurata em função de diferentes relações de K, Ca e Mg. Os tratamentos foram baseados no meio MS básico com relações K:Mg (mmol L-1) de: 22K:1Mg, 20K:3Mg, 16K:7Mg, 12K:11Mg, 8K:15Mg e 4K:19Mg; relações K:Ca (mmol L-1) de: 22K:4Ca, 20K:6Ca, 16K:10Ca, 12K:14Ca, 8K:16Ca e 4K:22Ca, com cinco repetições, sendo a parcela experimental composta de duas plântulas por frasco. Foram utilizados como explantes rizomas de plântulas in vitro, mantidas em sala de crescimento, a temperatura de 25±2 °C, sob irradiância 52 W m-2 s-1 e fotoperíodo de 16 horas. Após 80 dias de cultivo, as plântulas foram avaliadas em relação às variáveis: número de folhas, altura e comprimento da raiz. Posteriormente, foram determinadas as massas secas da parte área e raiz, relação parte aérea/raiz e realizada a análise química das folhas. Foi possível melhorar o crescimento das plantas de zingiberáceas avaliadas, na fase de micropropagação, mudando-se as concentrações de K, Ca e Mg da formulação original do meio MS, sendo recomendadas as concentrações de K de 22 mmol L-1 para Etlingera elatior e Zingiber spectabile e de 16 mmol L-1 para Alpinia purpurata e concentração de Ca de 4 mmol L-1 para Etlingera elatior e Zingiber spectabile, e entre 8 a 10 mmol L-1 para Alpinia purpurata. Uma maior concentração de Mg para o cultivo in vitro de Etlingera elatior é necessário. Para Zingiber spectabile e Alpinia purpurata são recomendadas a concentração proposta no meio MS de 3 mmol L-1 de Mg.Sociedade Brasileira de Floricultura e Plantas Ornamentais2019-02-22T11:16:23Z2019-02-22T11:16:23Z2016info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCOELHO, V.
