Foliar anatomy and morphological characterization of <i>Bambusa </i>vulgaris in the acclimatization phase

Abstract

This study was aimed to achieve the morphological and anatomical characterization of in vitro plants of Bambusa vulgaris Schrad. ex Wendl during acclimatization. The morphological development of the leaf and root in plants acclimatized with 0 and 90 days after planting, as well as field plants with more than 15 years of planting were considered. Results showed important differences between the structures of the leaf in the evaluated periods. Both presented adaxial and abaxial monostratified epidermis, with presence of trichomes, stomata, micro-hairs in the intercostal area. The abaxial surface showed silica and papilla cells. In the analysis of the cross section of leaf blade B. vulgaris were observed bulliform and fusoid cells, confirming the presence of the xylem, phloem, epidermis, cuticle, vascular bundles, the chlorenchyma showing differences among the development stages. The longitudinal cut to the root-stem junction demonstrated a further development in plants acclimatized for 90 days. Key words: bamboo, trichomes, leaf blade, stomata, epidermis.
