| Na produção de hortaliças orgânicas a utilização exclusiva de composto orgânico tem se mostrado uma prática onerosa, em função do grande volume exigido para se obter produções comerciais. Uma das alternativas para a adubação complementar das hortaliças é a utilização da adubação verde. O objetivo deste trabalho foi avaliar três espécies de adubos verdes, utilizadas em complementação ao composto orgânico, quanto ao aporte de nutrientes ao solo, a produtividade e às características agronômicas de alface americana e repolho. O experimento foi instalado na Universidade Federal de Lavras, em LavrasMG, no período de dezembro de 2001 a agosto de 2002. O solo foi classificado como LATOSSOLO VERMELHO Distrófico. O delineamento experimental foi o de blocos... |

| ABSTRACT The production of secondary metabolites from medicinal plants, also called Plant-Derived Medicinal Compounds (PDMC), is gaining ground in the last decade. Concomitant to the increase in the knowledge about pharmacological properties of these compounds, horticultural plants are becoming the most important, sustainable and low-cost biomass source to obtain high-complex PDMCs to be used as medicaments. Biotechnological tools, including plant cell and tissue culture and plant genetic transformation, are increasingly being employed to produce high quality and rare PDMC under in vitro conditions. The proper use of these technologies requires studies in organogenesis to allow for better control of in vitro plant development and, thus, to the production... |

| Plant regulators, as well as bioactive fractions of the organic matter, can accelerate the development and increase the efficiency of adventitious rooting in ornamental plants. We evaluated rooting in the Brazilian red-cloak (Megaskepasma erythrochlamys) and sanchezia (Sanchezia nobilis) cuttings in response to application of indole-butyric acid (IBA) and humic acids (HA). Stem cuttings of both species treated with solutions of 0, 250, 500, 1000, 2000 mg/L of IBA and 0, 10, 20, 30, 40 mmol/L of C of HA were placed in 2.0 L plastic pots containing carbonized rice husk, kept in greenhouse. Survival of cuttings, number of leaves and shoot and root fresh and dry matter were evaluated 45 days after. Data were used to run an analysis of variance. We observed the... |

| O projeto "Agricultura Apoiada pela Comunidade" (AAC) é uma alternativa de mercado utilizada na Europa e nos EUA. Neste mercado alternativo, os produtores oferecem a sua produção aos consumidores, sob a forma de cestas de alimentos, alguns meses antes de iniciarem a produção de suas culturas. Algum tempo depois, durante alguns meses, os consumidores irão receber os produtos. Atualmente, diversos países têm uma parcela significativa da sua população vivendo na pobreza. Por isso, diversas políticas públicas foram desenhadas nesses países com o objetivo de reduzi-la. O estímulo à agricultura urbana é uma dessas políticas. No entanto, frequentemente, os produtores urbanos pobres têm dificuldades para adquirir os insumos necessários para manter a sua produção.... |

| ABSTRACT: This study carried out agronomic evaluation and estimated the combining ability of tomato lines for the industrial segment, aiming to elect promising genotypes for breeding and to find simple hybrids with superior traits. Randomized-blocks design was used with 57 treatments (45 experimental hybrids, 10 lines and 2 checks treatments) with 3 replications. A complete diallel among 10 tomato lines for processing was used. Evaluated traits were: fruit total (YT) and commercial production (YC), pulp yield (YP), fruit average mass (MM) and total soluble solids content (TSS). Diallel crosses allowed synthesizing experimental hybrids with superior traits when compared to commercial hybrids. Non-additive effects prevailed over the expression of YT, YC, YP... |

| ABSTRACT The genotypes evaluation in a germplasm bank is essential to determine their commercial or usefulness, as potential parents, in a breeding program. We aimed to detect the genetic diversity of 42 tomato genotypes of cherry type, belonging to the germplasm bank of the Federal University of Uberlândia and, also evaluate their behavior. The experiment was conducted in a greenhouse in randomized block design with 42 treatments and two replications. Ten quantitative traits of agronomic importance were evaluated. The genetic divergence was obtained by multivariate analysis, using the Mahalanobis distance with different clustering methods (UPGMA and Tocher). The hybrids performance was compared by Scott-Knott (p= 0.05) and Dunnett’s test (p= 0.05). UPGMA... |

| In Brazil, the greengrocery market of sweet corn has been expanding along the country. In contrast, there have been few agri-industries canning sweet corn (Zea mays) because of the lack of cultivars with agronomic characteristics proper to industrial purposes. The purpose of this study was to evaluate the general combining ability (GCA) of seven inbred lines of sweet corn, and the specific combining ability (SCA) of their hybrid combinations based on their agronomic traits, and the chemical composition of the grain. In the growing season 2006/2007, twenty-one single hybrids were evaluated in the Iguatemi Research Station, Maringá County, Northwestern Paraná, in Brazil using a complete randomized block design with four replications. Data were subjected to... |
