| In the Brazilian Cerrado (neotropical savanna), the development of bud-bearing underground systems as adaptive structures to fire and dry periods can comprise an important source of buds for this ecosystem, as already demonstrated in the Brazilian Campos grasslands and North American prairies. Asteraceae species from both woody and herbaceous strata have subterranean organs that accumulate carbohydrates, reinforcing the adaptive strategy of these plants to different environmental conditions. This study aims to analyse the morpho-anatomy of underground systems of six species of Asteraceae (Mikania cordifolia L.f. Willd., Mikania sessilifolia DC, Trixis nobilis (Vell.) Katinas, Pterocaulon alopecuroides (Lam.) DC., Vernonia elegans Gardner and Vernonia... |

| O camu-camu [Myrciaria dubia (Humb., Bonpl. & Kunth) McVaugh], da família Myrtaceae, é encontrado em áreas inundáveis da Região Amazônica e utilizado como conservante em antioxidantes por seu alto teor de ácido ascórbico. O objetivo deste trabalho foi avaliar porta-enxertos desta família, adaptados a terra firme, visando à propagação vegetativa de camu-camu. Selecionaram-se duzentas e quarenta mudas de camu-camu, goiabeira (Psidium guajava L.) e pitangueira (Eugenia uniflora L.), que receberam quatro tipos de enxertia, originando doze tratamentos de sessenta plantas, com cinco repetições. Apenas o porta-enxerto de camu-camu se mostrou compatível. A incompatibilidade entre camu-camu e os porta-enxertos de goiabeira e pitangueira foi demonstrada por... |

| Smilax L. species, popularly known in Brazil as salsaparrilha, have been used in folk medicine as tonic against rheumatism and as anti-syphilitic since the sixteenth century; however, until today, their roots have been explored in an extractive way. The aim of this study was to analyze the propagation of Smilax fluminensis aiming to meet the demand and to propose procedures for its sustainable management. It was analyzed the percentage of seed germination, rooting of aerial and subterranean stem cuttings and plant resprouting capacity after removal of the shoots. The monitoring lasted one year. Seeds were subjected to temperatures: 25°C, 30°C, 20-30°C and 20-35°C under a daily photoperiod of eight hours and in the absence of light. For rooting the stem... |

| Thiamethoxam is a systemic insecticide from the neonicotinoid group, nitroguanidin family which affects the nicotinic receptor acetyl choline in the insect membrane, wounding the nervous system and causing the death of the insect. It was used with success in the control of initial pests of several crops. It was considered that thiamethoxam has a bioactivator effect, because in the absence of insects promoted increase in vigor, development and productivity of crops. This work was carried out to verify if thiamethoxam causes histological changes in sugarcane roots. In this work, it was used optical microscopy, images arrest, tissue biometrics and statistical analysis, in young roots of sugarcane RB 83 5486 after the treatments with different thiamethoxam... |
