| The experimental studies were conducted in 2007-2008, 2008-2009 and 2009-2010 crop seasons, in order to know the agro-economic yield of 'Chinês' and "Macaquinho" taro clones, propagated using huge, extra, large, medium, small and tiny cormels. The harvest was done on average on 202 days after planting, in three crop seasons. Based on the joint analysis of variance carried out, it was observed that taro clones showed significant differences in the yield of fresh and dry weight of leaves, cormels, and commercial and non-commercial comels; besides, there were significant differences in yield of a crop season to another and the size of the cuttings induced significant differences in yield. In the conditions that the experiments were conducted, and considering... |

| Aspects related to the nature of stem thickening in monocotyledons have been the subject of many studies. Primary thickening has been attributed to the Primary Thickening Meristem (PTM). According to most authors, it gives rise, besides the adventitious roots, to the vascular tissues and part of the cortex. In other words, it has centripetal and centrifugal activity. For some authors, however, it gives rise only to the vascular system, and for others, only to part of the cortex. However, this work demonstrated that PTM corresponds to the pericycle in the meristematic phase or to the pericycle associated with the endodermis, also with meristematic activity. It was observed that the pericycle was responsible for the formation of the vascular system of the... |

| Cyperaceae are usually perennial, with underground stems mainly rhizomatous, however, other stem types may also occur, such as corms and tubers. The underground stems of five Cyperaceae species were examined. Cyperus rotundus and Fuirena umbellata have plagiotropic rhizomes, while C. esculentus, C. odoratus, Hypolytrum schraderianum and Bulbostylis paradoxa have orthotropic rhizomes. Corms occur in C. rotundus and C. esculentus, and stolons in C. esculentus. The primary body originates from the activity of the apical meristem and later, from the primary thickening meristem (PTM). Secondary growth results from secondary thickening meristem (STM) activity, and occurs in rhizomes of H. schraderianum, B. paradoxa, C. odotarus and F. umbellata. The procambium... |

| ABSTRACT The aim of this study is to compare physiological development of Heliconia bihai cv. Lobster Claw Two plants derived from in vitro culture of zygotic embryos and conventional propagation. Heliconias obtained from rhizomes and from in vitro multiplication were evaluated every 30 days during ten months under greenhouse conditions. The experimental design was completely randomized, with ten repetitions, and the 2x10 factorial arrangement consisted of two plant multiplication methods and ten evaluations performed at different times. The analyzed biometric parameters were plant height, number of leaves, number of tillers, leaf area, and color intensity in the bracts. Plants derived from in vitro culture showed significant differences in the development... |

| Las heliconias son plantas ornamentales tropicales cultivadas como flor de corte por sus colores brillantes y formas exóticas. Su cultivo en México ha tenido un crecimiento lento por las dificultades que presentan para su propagación. Una alternativa para la propagación clonal es el uso de técnicas de cultivo de tejidos vegetales in vitro. En esta investigación se desarrolló un protocolo para la producción de plántulas de Heliconia collinsiana, H. nickeriensis y H. psittacorum x H. spathocircinata cv. ‘Golden Torch’ vía organogénesis directa a partir de yemas laterales de rizomas procedentes del campo. La mezcla de 30% de hipoclorito de sodio (v/v), 4% de Tween® 20 (v/v) y 3% de plata coloidal (v/v) fue eficiente para abatir la contaminación de... |

| Brazilians have been using the underground organs of Smilax species in alternative medicine since the 19th century because of their anti-rheumatic qualities. However, even nowadays, these species are explored only by extractivism. Studies on seed germination and development of these organs could be useful to preserve these plants. After germination, seedling development of Smilax polyantha was analyzed to understand underground stem formation. Furthermore, to analyze the ontogenesis of the underground system, seedlings aged from one to twelve months were sectioned. One of the most striking features of this species is the presence of two stem branching systems. The plumule gives rise to the first stem branching system with negative geotropism. Its first... |
