| ABSTRACT The selection of kale genotypes more resistant to dehydration is important, since this product is marketed fresh and characterized as perishable. For the post-harvest study, the adjustment of regression models is useful. However, when there are many treatments, it is difficult to identify the superior one through the graphical representation of the curves. In this sense, the model identity test groups the curves establishing genotypes that have statistically similar behavior. Thus, we aimed to select kale accesses for post-harvest dehydration using the model identity test. The accumulated loss of fresh matter of 22 kale genotypaes was evaluated, being 19 of the germplasm bank of the UFVJM and three commercial cultivars (COM). The model identity... |

| ABSTRACT This research was installed to study plant growth of sweet potato and identify the most favorable harvest time for both roots and the aboveground part (stems). The experiment was carried out at the JK campus of the Federal University of the Vale do Jequitinhonha e Mucuri, in Diamantina, MG, complete blocks at random, with four replications. Three plants in the central part of the experimental plots were collected in twelve consecutive harvests at 15-day intervals. Plants were fractionated in roots, stems, and leaves to determine the dry matter of each part. Leaf area was also measured and growth rates were calculated. Data were analyzed by means of regression. Plants reached the highest dry matter accumulation between 75 and 156 days after... |

| Desenvolveu-se uma técnica de detecção rápida de Ceratocystis fimbriata em lenho de eucalipto (Eucalyptus spp.) infetado, visualizando-se clamidósporos (aleuroconídios) ao microscópio ótico comum, em vasos do xilema, medula e raios medulares, a partir de cortes histopatológicos à mão livre, feitos com lâmina de barbear, ao microscópio estereoscópico. O tempo médio gasto para a detecção do patógeno, do corte histopatológico tangencial à total visualização dos clamidósporos ao microscópio ótico comum, foi de 3,5 min e bem menos utilizando-se corte longitudinal passando pela medula, contra, no mínimo, quatro a cinco dias, usando-se outras técnicas como o isolamento em BDA, deposição de fragmentos de lenho doente entre fatias de cenoura usadas como isca, ou... |

| Intercropping is a common practice among farmers in tropical regions of the world and has persisted for years, not only for traditional reasons, but also for certain advantages that helped in its ecological adaptation. In regard to low income farmers with small areas for cultivation, more attention should be given to the cost of production and better land management. Thus, the aim of this work was to determine the best intercropping system of cassava with other crops. The experiment was conducted in an area belonging to the cassava (Manihot esculenta) producers of the Planalto de Minas district in Diamantina, Minas Gerais State, Brazil. The treatments comprised cassava intercropped with maize, beans and dwarf pigeon pea, as well as controls with and... |
