“…Em Alpinia speciosa L., Bell (1979) verificou a existência de dois sistemas caulinares, um aéreo e outro do tipo rizoma com crescimento horizontal, sendo formado a partir de uma ou duas gemas laterais, originadas de órgãos subterrâneos precedentes. Segundo esse autor, padrão semelhante de ramificação é observado para Heliconia rostrata Ruiz & Pav.…”

-(Morphology and anatomy of the shoot system of Canna edulis Kerr-Gawler (Cannaceae)). The purpose of this research was to study the morpho-anatomical characteristics of the shoot system of Canna edulis. The observation of the buds and shoot system development were made during the vegetative cycle of the plant. The underground system is formed by fibrous adventitious roots originated from nodes and internodes of the rhizomes. These organs are oriented parallel to the surface of the ground, presenting a pattern of sympodial branching. The apical buds of the rhizomes are differentiated in reproductive stems, constituted by distinctive nodes and internodes. The base of this organ is constituted by cataphylls. The reproductive stem is formed by uniseriate epidermis, and in the subepidermical position there are cells with Casparian strips. The adult rhizome consists of the epidermis, cortex with a clear endodermis and vascular cylinder delimited by pluriseriate pericycle. Although the morphological characteristics of the shoot system of this plant agree with recent descriptions applied to the rhizophore, the underground stem of this species was interpreted as a rhizome.Key words -anatomy, buds, Canna, morphology, rhizomes RESUMO -(Morfoanatomia do sistema caulinar de Canna edulis Kerr-Gawler (Cannaceae)). O objetivo deste trabalho foi estudar características morfológicas e anatômicas do sistema caulinar de Canna edulis. As observações morfoanatômicas, de crescimento das gemas e formação do sistema caulinar, foram efetuadas durante o ciclo vegetativo da planta. O sistema subterrâneo é formado por raízes adventícias fibrosas originadas a partir dos nós e entrenós dos rizomas. Esses órgãos orientam-se paralelamente à superfície do solo com padrão de ramificação simpodial. As gemas apicais dos rizomas diferenciam-se em caules reprodutivos, constituídos por nós e entrenós característicos. A base desse órgão é constituída por catafilos. O caule reprodutivo é formado por epiderme unisseriada e em posição subepidérmica, nota-se a presença de células com estrias de Caspary. Os rizomas adultos são constituídos por epiderme, córtex com endoderme evidente e cilindro vascular delimitado por periciclo plurisseriado. Embora as características morfológicas do sistema caulinar dessa planta concordem com as descrições recentes aplicadas aos rizóforos, o caule subterrâneo desta espécie foi interpretado como um rizoma.

“…Some clonal species follow strict constructional rules (e.g. Bell 1979, Noble et al 1979, while others can alter their clonal growth (see review in Kroon and Hutchings 1995) in response to their abiotic environment (e.g. Slade and Hutchings 1987a, b), intensity of competition (e.g.…”

This study was motivated by the fact that although the plasticity of its above-ground organs is obvious in natural conditions and there are many data on the plasticity of Solidago's rhizome system in glasshouse experiments, there are no data on below-ground plasticity under natural conditions. We compared the morphology of rhizomes in two, contrasting habitats. We found that rhizome system responded to environmental conditions: in the dry habitat, ramets developed more but shorter rhizomes compared to the wet habitat. The decrease in rhizome length can be explained by the decrease in the size of above-ground organs, but the increase of rhizome number cannot. The most important regulating factor of rhizome growth is probably its mechanical restriction by the root biomass of other species.
