Abstract: field trials were conducted at epamig, lavras, brazil, from may to october/95, to indicate productive garlic cultivars with industrialization characteristics. the experimental design was of randomized complete blocks with four repetitions and seven treatments: dourado de castro, chines?o, gigante de curitibanos, gigante de lavínia, amarante, cará and gigante roxo. the commercial bulb yield varied from 7.37 to 14.72 t/ha, the most productive ones being the gigante curitibanos (14.72 t/ha) and dourado de castro (14.29 t/ha), with no significant difference, followed by cultivars presenting yield over 7.00 t/ha. a variation occurred from 18.00 (amarante) to 59.25 g/bulb (gigante roxo) and from 8.20 (chines?o) to 33.78 cloves/bulb (dourado de castro). cultivars presented no significant differences for total and soluble solids, with values over 36.95 and 36.00%, respectively, besides presenting good characteristics for industrialization.

Abstract: this study was carried out from march to september of 1995, in the experimental field of epamig, lavras-mg, brazil, with the objective of determining the physico-chemical and chemical composition of onions from different cultivars (allium cepa l.). the experimental design was completely randomized blocks with four repetitions and six cultivars as follow: baia periforme, crioula, granex 33, pira ouro, jubileu and texas grano 502. after the cure it was evaluated the ph, soluble and total solids (%), titrate acidity (%), pyruvic acid (μmol/g), total sugar, reducers and non reducers (%) and industrial index. the cultivars crioula, baia periforme, pira ouro and jubileu showed the largest concentrations of total and soluble solids. the highest acidity indexes were observed in the cultivars crioula (0.370%) and pira ouro (0.315%). the largest industrial indexes were found in the cultivars crioula (0.87) and baia periforme (0.75), and the smallest ones in the cultivars texas grano 502 (0.51) and granex 33 (0.32).

Abstract: the main purpose of this study was to evaluate sensorial attributes of coffee grown under a transition cultivation system, from conventional to organic, in lavras (mg). the experiment was established in 2004, in a conventional field with 6 year-old catuaí amarelo iac86 coffee plants, planted using 4,0 x 0,6 m spacing system. the experimental design for organic treatments was the balanced lattice design 4 x 4, with five replicates in factorial scheme 3 x 2 x 2, and 4 additional treatments. three sources of organic matter were used for the factorial scheme: castor bean bran, chicken litter and cattle manure, with or without application of coffee straw and green manure with pigeonpea (cajanus cajan l. millsp.). the four additional treatments were composed by: treatment 1: cattle manure + coffee straw + coal bran + double potassium and magnesium sulphate; treatment 2: castor bean bran + coffee straw + rock bran; treatment 3: coffee straw; treatment 4: green manure. as a control, a group of coffee plants managed under conventional cultivation system was kept in the same experimental plot. in the first year, no significant differences were observed on the cup quality among grains from conventional and organic plants of all treatments. in the second year, cup quality of some organic treated plants was superior when compared to conventionally treated plants. a positive effect on sensorial attributes was observed using cattle manure, either alone or associated with coffee straw and green manure.

Abstract: this study was conducted in a freshwater tilapia farm that has not used any antibiotic. it was selected one pond, caught 15 fishes and collected samples of intestinal content and mucus surface, water influent and pond water, ration, fresh tilapia fillets and frozen fillets.. phenotypical characteristics, gram stain, oxidase production, oxidative-fermentative utilization of glucose (o-f) were determined of representative colony. were selected 89 strains and submitted for antimicrobial sensitivy test using several antibiotics. the major identified bacterial families were belonged enterobacteriaceae and vibrionaceae. the most isolates showed resistance to ampicilin and eritromicin. from the 89 isolates evaluated 74 (83%) showed a multiple antibiotic resistance index (mar) 3 0.2, that mean resistance to two or more antibiotics. the mar índice frequency were higher and bigger in the rations.

Revista Brasileira de Engenharia Agrícola e Ambiental , 2001, DOI: 10.1590/S1415-43662001000300004
Abstract: the main purpose of testing equipments used in sprinkler irrigation systems is to determine the hydraulic characteristics and to analyze the performance of these equipments. this work aimed at evaluating the performance of two models of the supermamkad minisprinklers, regulated and unregulated yellow models and unregulated violet. the tests sought the determination of the following parameters: water distribution uniformity, manufacturing variation coefficient, mean effective wetted radius and water distribution profile. also, the best sprinkler spacing for the vegetables was simulated. the analyses have demonstrated that all models tested produced a manufacturing variation coefficient lower than 5%, classifying them in category a. according to simulations, it was possible to conclude that the emitter can work under the pressures of 250, 250 and 300 kpa, respectively for the violet and regulated and unregulated yellow models.

Abstract: this work was developed with the objective of evaluating the hydraulic characteristics of three models of the compensating mini-sprinkler, manufactured by dan sprinklers. evaluated were the variation due to manufacturing process, water distribution uniformity, discharge-pressure relation (mini-sprinkler characteristic equation), aiming to provide suggestions for their adequate selection for trickle irrigation systems designs. both models were classified as a category because of the low manufacturing variation coefficient obtained (< 5%), and the yellow model exhibited the best water distribution uniformity.

Abstract: species from genus aspidosperma (apocynaceae) are popularly employed to treat various diseases. this genus is characterized by the occurrence of indole alkaloids. taking into account the various biological activities attributed to these alkaloids, the description of the chemical diversity in genus aspidosperma is important. a review of simple carbolinic alkaloids isolated from species of various genera was published in 1979. in 1987, it was published another one dealing with the relationships between the chemical structures of the indole alkaloids and the evolution of aspidosperma species. this work updates the information about the indole alkaloids isolated from aspidosperma species.
