Rhizophores in Rhizophora mangle L: an alternative interpretation of so-called ''aerial roots''

Abstract: Rhizophora mangle L., one of the most common mangrove species, has an aerial structure system that gives it stability in permanently swampy soils. In fact, these structures, known as " aerial roots" or " stilt roots", have proven to be peculiar branches with positive geotropism, which form a large number of roots when in contact with swampy soils. These organs have a sympodial branching system, wide pith, slightly thickened cortex, collateral vascular bundles, polyarch stele and endarch protoxylem, as in the s… Show more

“…Its origin is from the axillary bud of the first cataphyll at the plumular axis and not from cotyledonary buds as previously reported for other Smilax species. (Menezes 2006) or from the first axillary bud of the plumular axis as described in S. polyantha.…”

“…Entretanto, Menezes (2007) afirma que esta estrutura de Cordyline fruticosa é um rizóforo (que significa "portador de raiz"). A primeira publicação que trata de rizóforos em angiospermas no Brasil foi o de Menezes (1975), em espécies de Vernonia (Asteraceae) da Serra do Cipó.…”

“…Em Smilax quinquenervia o rizóforo surge a partir de uma gema presente no nó cotiledonar (Andreata & Menezes 1999 De maneira similar à Gill & Tomlinson (1977) que enumeram as diferenças entre o que era denominado raízes aéreas e as raízes subterrâneas, Menezes (2006) analisou as peculiaridades dos ramos com geotropismo positivo, e constatou inúmeras exceções no caso da estrutura ser considerada uma raiz. Entre os aspectos analisados pelos três pesquisadores, estão o fato dessa estrutura possuir protoxilema endarco, enquanto que as raízes subterrâneas possuem protoxilema exarco e a ocorrência de feixes, contrastando com as raízes, as quais possuem cordões de xilema e floema independentes não formando feixes vasculares.…”
