O objetivo deste trabalho foi avaliar o possível transporte de glicosídeos cianogênicos de folhas de clones de copa de seringueira (Hevea spp.) resistentes ao mal-das-folhas para o tronco dos clones de painel em que estão enxertados. O potencial cianogênico (HCNp) dos clones de copa foi determinado na casca do tronco, a diferentes distâncias do câmbio, e o seu gradiente foi avaliado ao longo do tronco. Avaliou-se, também, a correlação entre o HCNp das folhas das copas e o da casca do tronco. O HCNp determinado nas folhas apresentou ampla faixa de variação nas espécies estudadas como clones de copa, com os menores valores registrados em clones de H. nitida e os maiores em H. rigidifolia. Na casca do tronco, a camada de tecido mais próxima ao câmbio apresentou valores mais elevados de HCNp. Um gradiente basípeto positivo foi observado ao longo do tronco, ou seja, houve aumento do HCNp do ápice para a base. Apesar de os clones de copa influenciarem o potencial cianogênico na casca do tronco dos clones de painel, a ausência de correlação entre o HCNp das folhas e o do tronco indica que a copa não é a fonte principal dos glicosídeos cianogênicos encontrados no tronco. |

The geographical extent of Brazil exceeds 8.5 million km2 and encompasses a complex mix of biomes and other environmental conditions. Multipe decision support tools are needed to help support management of these diverse Brazilian natural resources including ecohydrological models. The use of the Soil and Water Assessment Tool (SWAT) ecohydrological watershed-scale model in Brazil has increased greatly during the past decade. Well over 100 SWAT studies were identified in this review which have been published during 1999 to 2015 in Brazilian and international journals, conference proceedings, and as theses or dissertations, many of which are written in Portuguese. The majority of these studies (102 total) are reviewed here as part of an extensive survey covering the 1999 to 2013 time period. Temporal and spatial distributions, a summary of hydrologic calibration and validation results and a synopsis of the types of applications that were performed are reported for the surveyed studies. A smaller subset of recent Brazilian studies published in English between 2012 and 2015 in scientific journals are also reviewed, with emphasis on hydrologic and sediment transport testing results as well as scenario applications that were performed. The majority of the surveyed SWAT studies were performed for watersheds located in the South and Southeast regions of Brazil (67%) and were conducted in the context of academic research. Nearly 50% of the surveyed studies reported only hydrologic results. Similar trends were found for the subset of more recent English publications. Limited studies have been reported that describe applications of SWAT in Brazil by private firms or government agencies; this review indicates that the potential exists for increased numbers of such studies in the future. However, there is evidence that a lack of accessibility to adequate quality input data is a possible hindrance to the more general use of SWAT for watershed applications in Brazil.
