Resumo: | Considering the importance of knowledge of anatomical structures in the protocol definition for the micropropagation of the ipê-branco, this study compared the in vitro and ex vitro internal structure of leaves. For anatomical evaluations, the first leaf in vitro with 30 days of growth and adult plants were used. The anatomical study of leaves was based on microscope examination from cross-sectional and paradermic sections from the leaf blade. The leaf structures from plants ex vitro show uniseriate skin, and mesophyll with dorsiventral organization. They are hipostomatics and trichome is present in all faces. Leaves ex vitro was thicker that culture in vitro in limb, central nervure, epidermis and palisade and spongious parenchyma. In leaves in vitro, cuticle and sclerenchyma are absent. Leaves of ex vitro presented minor numbers of stomata and greater number of trichromes when compared with culture in vitro. Stomata of in vitro are larger than stomata ex vitro. |

Para as avaliações anatômicas foram utilizadas folhas do primeiro nó de ramos, da base para o ápice, com 30 dias de cultivo in vitro e de plantas de campo. O estudo anatômico foi feito por meio das secções transversais e paradérmicas das folhas. As folhas apresentam epiderme uniestratificada e mesofilo dorsiventral. São hipostomáticas e apresentam tricomas em todas as faces. Folhas de plantas cultivadas ex vitro, quando comparadas com in vitro, tiveram espessura do limbo foliar, nervura central da epiderme adaxial e abaxial e os parênquimas paliçádico e esponjoso maiores. Em folhas oriundas do cultivo in vitro, a cutícula e o esclerênquima são ausentes. Folhas de plantas cultivadas ex vitro apresentaram menor número de estômatos e maior número de tricomas, quando comparadas com o cultivo in vitro. Os estômatos de folhas cultivadas in vitro são maiores que os de folhas ex vitroUniversidade Estadual De Maringá2009-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/193710.4025/actascibiolsci.v31i3.1937Acta Scientiarum.
