Resumo: | This work evaluated the influence of seal type and substrate type on pre-acclimatization, and symptomatological aspects relating to acclimatization of ipê-roxo. For the pre-acclimatization, ipê-roxo plants obtained through an in vitro zygotic embryo culture were aseptically inoculated in test tubes with different types of seal (cotton plug, plastic cap + parafilm and plastic lid) and different substrates (agar, vermiculite and Plantmax®) supplemented with a WPM culture medium with 1 gL-1 of activated charcoal, 10 mgL-1 of citric acid and 30 gL-1 of sucrose added. For the acclimatization, in vitro ipê-roxo plants were transplanted into 56-cm3 plastic tubes containing vermiculite and Plantmax® at a 2:1 ratio which had been previously autoclaved at 121oC and 1 atm for 20 minutes. Once transplanted, the plants were irrigated with different concentrations of the MS medium (25%, 50%, 75%, 100% and 150%), using distilled water as control. After 30 days, the effects of seal type and substrate type on pre-acclimatization were examined. Cotton can be recommended where Plantmax® or vermiculite is used as substrate. In the acclimatization it was noted that where plants were irrigated with distilled water and concentrations < 50% they showed symptoms of nutritional deficiency. Similar symptoms were observed when using MS medium at a concentration equal to or greater than 100%. The 75% MS concentration was found to be the most effective at maintaining the nutritional vigor of ipê-roxo seedlings in the process of acclimatization. |

Para pré-aclimatização, plantas de Ipê-roxo obtidas in vitro por meio de cultura de embriões zigóticos foram inoculadas assepticamente em tubos de ensaio contendo diferentes tipos de vedação (algodão, tampa plástica + parafilme e tampa plástica) e diferentes substratos (ágar, vermiculita e Plantmax®) suplementados com meio de cultivo WPM acrescidos de 1 gL-1 de carvão ativado, 10 mgL-1 de ácido cítrico e 30 gL-1 de sacarose. Para a aclimatização, plantas de Ipê-roxo obtidas in vitro foram transplantadas para tubetes de 56 cm3, contendo vermiculita e Plantmax® na proporção 2:1, previamente autoclavado a 121oC e 1 atm, por 20 minutos. Após o transplantio, as plantas foram irrigadas com diferentes concentrações do meio MS (25%, 50%, 75%, 100% e 150%), sendo utilizada como controle água destilada. Após 30 dias, foram verificados efeitos do tipo de vedação e substrato na pré-aclimatização. O algodão pode ser recomendado quando se utiliza Plantmax® ou vermiculita como substrato. Na aclimatização, verificou-se que as plantas quando irrigadas com água destilada e concentrações < 50% apresentaram sintomas de deficiência nutricional. Foram observados sintomas semelhantes com a utilização de MS em concentração igual ou superior a 100%. A concentração 75% do meio MS foi a mais eficiente na manutenção do vigor nutricional de mudas de Ipê-roxo em processo de aclimatização.Universidade Federal de Lavras (UFLA)2015-05-122017-08-01T20:17:08Z2017-08-01T20:17:08Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfMARTINS, J.
