Dissimilarity between Mouriri elliptica (Mart.) plants cultivated in vitro and in situ through anatomic parameters

Mouriri elliptica (Mart.) is a genetic resource of the Cerrado domain, which has potential for food and medicinal use. A few studies have been performed on its in vitro propagation, and no studies have examined dissimilarities between plants of this species when cultivated in situ or in vitro. Therefore, the objective of the present study was to identify in vitro cultivation conditions that permit the formation of plantlets with leaf anatomical features that are less dissimilar to those of plants grown in situ. Thus, an anatomical study of the leaves was conducted to investigate the adaxial epidermis thickness, abaxial epidermis thickness, chlorenchyma thickness, stomatal crypt depth, stomatal crypt density, and leaf surface stomatal crypt aperture area. The distance between phenotypes was determined based on micromorphometric data, and unweighted pair group mean arithmetic clustering was performed. Four different groups were tested, and cultivation with sucrose and 50 and 75 μmol⋅m⋅s irradiance was found to promote plantlet development and maximize similarity to plants cultivated in situ. The most important anatomical parameters in this study were the stomatal crypt aperture area and the crypt density. This study is of importance for the anatomical characterization of M. elliptica (Mart.) leaves, as it identifies plasticity as a function of in vitro culture conditions.

“…Similar results were also reported by Oliveira et al (2010) during the acclimatization of Z. spectabile, with the use of other substrates and inoculated with fungus arbuscular mycorrhizal fungi. Others species of Zingiberales (Etlingera elatior, Zingiber officinal, Heliconia velloziana) also presented great survival to acclimatization process (GIRARDI and PESCADOR, 2010;DAS et al, 2013;QUISEN et al, 2014;RODRIGUES et al, 2015).…”

Zingiber spectabile is a tropical ornamental species with difficulties to obtain efficient propagation system. Thus, this study aimed to assess the in vitro propagation of Zingiber spectabile. Seed characterization was determined by measuring length, width and thickness, the weight of 1000 seeds and imbibition curve. In vitro germination of seeds was at constant (25 °C) or alternating temperatures (20-30 ºC). For optimization of in vitro multiplication, different concentrations of activated charcoal (0.0, 0.1 and 0.3%) and sucrose (0.0, 0.1, 0.3, 0.5 and 0.7 M) were evaluated. Plantlets were inoculated in flasks with different sealing systems (PVC covers with or without filters at the center) and culture media (MS or WPM). The plants were acclimatized in Plantmax ® substrate. Seeds were of 6.06 mm length, 3.22 mm wide and 2.83 mm thick. The weight of 1,000 seeds corresponded to 46.4 g. The seed imbibition curve approaches to a tree phase pattern. Alternating temperatures induced high germination rates (68%). The addition of 0.3% activated charcoal provided higher root growth and plants with smaller number of senescent leaves. The best plant growth was obtained by the use of 0.1 M sucrose. All acclimatized plants survived (100%). The results demonstrate that Z. spectabile respond well to in vitro propagation. Keywords: beehive ginger, micropropagation, tropical plants. RESUMO Propagação in vitro de Zingiber spectabileZingiber spectabile é uma espécie ornamental tropical com dificuldades para se obter um sistema de propagação eficiente. Assim, este estudo teve como objetivo avaliar a propagação in vitro de Z. spectabile. A caracterização das sementes foi determinada pela medição do comprimento, largura e espessura, pelo peso de 1.000 sementes e pela curva de embebição. A germinação in vitro das sementes foi avaliada em temperatura constante (25 °C) ou alternada (20-30 ºC). Para a otimização da multiplicação in vitro, diferentes concentrações de carvão ativado (0,0, 0,1 e 0,3%) e sacarose (0,0, 0,1, 0,3, 0,5 e 0,7 M) foram avaliadas. As plântulas foram inoculadas em frascos com diferentes sistemas de vedação (tampas de PVC com ou sem filtros no centro) e meio de cultura (MS ou WPM). As plantas foram aclimatizadas em substrato Plantmax®. As sementes apresentaram comprimento de 6,06 mm, largura de 3,22 cm e espessura de 2,83 mm. O peso de 1000 sementes correspondeu a 46,4 g. A curva de embebição de sementes se aproxima de um padrão trifásico. Temperaturas alternadas induziram altas taxas de germinação (68%). A adição de 0,3% de carvão ativado proporcionou maior crescimento radicular e plantas com menor número de folhas senescentes. O melhor crescimento de plantas foi obtido pelo uso de sacarose 0,1 M. Todas as plantas aclimatizadas sobreviveram (100%). Os resultados demonstraram que Z. spectabile responde bem à propagação in vitro. Palavras-chave: sorvetão, micropropagação, plantas tropicais.
