Endoderme com atividade meristemática em raiz de Canna edulis Kerr-Gawler (Cannaceae)

Abstract: RESUMO -(Endoderme com atividade meristemática em raiz de Canna edulis Kerr-Gawler (Cannaceae)). Canna edulis é uma planta ornamental utilizada em muitos países como fonte alimentar alternativa. O objetivo deste trabalho foi descrever a formação do córtex radicular a partir da análise anatômica da região apical. Na região situada a 220µm do pró-meristema, os tecidos meristemáticos apicais já se apresentam organizados em protoderme, meristema fundamental e procâmbio. Em fase subseqüente na diferenciação celular… Show more

“…The layers of the inner root cortex, adjacent to the endodermis, are stratified close to the root apex, indicating that the inner cortex originates from a meristematic endodermis, as demonstrated by Alonso et al (2004) and by Menezes et al (2005) for other monocotyledons.…”

“…Only Melo-de-Pinna & Menezes (2003), Machado et al (2004), Alonso et al (2004) and Menezes et al (2005), citing Williams (1947) described recently, the layers of radiate cortical cells as being the result of an endodermis with meristematic activity. In the present work, corroborating that established by Menezes et al (2005), these same radiate rows of cells are denominated Derivatives of the Meristematic Endodermis (DME).…”
