2. Watercress crop to salinity using a NFT hidroponic system / Resposta da Cultura do Agrião à Salinidade Utilizando um Sistema Hidropônico do Tipo NTF
After the Brazilian agriculture started to be outstanding in the scenery of the scientific researches, the great challenge started to be the productivity standardization in whole national territory. One of the main focus is being the semi-arid area for its water scarcity, so much quantitative as qualitative, for being an area with low annual precipitation an

3. Produção de forragem verde em sistema hidropônico usando esgoto tratado
In the urban areas of the cities a larger problem of destiny of effluents of the treatment stations is verified due to the junction of the sewages in great volumes. This way the hidroponic cultive becomes important, for your intensive characteristic, as alternative of reuse. This work presents as objective the improvement of the relation hidric-nutritious of

4. Influence of the native microbiota and of physical- chemical factors in adhesion of Salmonella Enteritidis in lettuces of hydroponic and conventional sistems / Influência da microbiota natural e de fatores físico-químicos na adesão de Salmonella Enteritidis em alface de cultivo hidropônico e convencional
Adhesion of Salmonella Enteritidis in lettuces leaves of hidroponic and convencional systems was evaluated in reason of the native microbiota, with or without sanitization with chlorinated organic compound and vegetal roughness, using Atomic Force Microscopy. Besides, surfaces hydrophobicities of the lettuce leaves and S. Enteritidis were determined, through

5. FREQÜÊNCIA DE AMOSTRAGEM DE PLANTAS DE ALFACE HIDROPÔNICA PARA AJUSTE DE CURVAS DE CRESCIMENTO / HIDROPONIC LETTUCE SAMPLING FREQUENCY TO ADJUST GROWTH CURVES
In order to construct growth curves is necessary a sequence of many samples taken during lettuce growth period. However, mainly when the trial is made in a controlled environment, sampling frequency is limited. This work was carried out with the aim to reduce sampling destruction effect without change the result precision. Two field trials were made in a con

6. Rendimento e qualidade de sementes de frutos de tomate em diferentes estádios de maturação produzidos nos sistemas hidropônico e convencional / Productiveness and quality of seeds of tomatoe in different periods of maturation produced in the hydroponic and conventional systems
A técnica do fluxo laminar de nutrientes vem contribuindo para a disseminação do cultivo hidropônico comercial em todo o mundo, inclusive no Brasil. A fim de avaliar a eficiência dessa técnica na produção de sementes de tomate (Lycopersicon esculentum Mill.), conduziu-se um experimento na fazenda-escola da FAZU, em Uberaba, colhendo-se os frutos em q

7. Rendimento e qualidade de sementes de frutos de tomate em diferentes estÃdios de maturaÃÃo produzidos nos sistemas hidropÃnico e convencional / Productiveness and quality of seeds of tomatoe in different periods of maturation produced in the hydroponic and conventional systems
The NFT - Nutriente Film Technique - has contributed to the dissemination of the commercial hydroponics cultivation all over the world and in Brazil as well. In order to evaluate the efficience of this technique in the production of tomato seeds (Lycopersicon esculentum Mill.), an experiment was conducted at a school-farm of FAZU, in Uberaba, it had been har

8. PRODUCTION AND BROMATOLIGAL COMPOSITION IN HIDROPONIC WHEAT FORAGE / PRODUÇÃO E COMPOSIÇÃO BROMATOLOGICA DA FORRAGEM HIDROPÔNICA DE TRIGO
Hydroponics forage is an alternative to producers who need quality food to their animals, at times of the year with low demand. It was carried out two experiments inside a polyethylene greenhouse (tunnel), in the Ecophysiology and Hydroponic Research Center (NUPECH), of the Federal University of Santa Maria, Brazil. The objective this work was to evaluate th

9. Uptake and remobilization of NO3 - in rice (Oryza sativa L.): Proton pumps activity and dynamics of the process / Absorção e remobilização de NO3 - em arroz (Oryza sativa L.): Atividade das bombas de prótons e a dinâmica do processo
The nitrogen metabolism of rice (Caiapó variety) was studied under nitrate starvation in hidroponic culture. Thirty days after germination half of the plants continued to receive the nutrient solution, while the other group was maintained without solution change and monitored until the exhaustion of NO3 -. The depletion of NO3 - resulted in greater decrease

10. Detecção e quantificação de sementes de soja geneticamente modificada resistente ao glifosato em sistema hidroponico / Detection and quantification of genetically modified soybean seeds resistant to glyphosate in hydroponics system
This work aimed at to establish a detection protocol to genetically modified (GM) soybean seeds resistant to the glyphosate, characterize the symptoms of the seedlings, and verify the efficiency of the hidroponic cultivation in the detection and quantification of GM soybean seeds mixtures in conventional seeds samples. Five assays were performed to establish

11. Parâmetros de crescimento e marcha de absorção de nutrientes na produção de minitubérculos de batata cv. Atlantic. / Growth parameters and uptake rate in potato cv. Atlantic minituber production.
As potato is the most important economic annual staple crop in Brazil and its production involves high costs, new alternatives are being adopted to decrease costs and obtain high quality potato seed. This study aimed at determining the growth parameters and the uptake rate by seedling from cv. Atlantic to be used for minituber production in a hydroponic syst

12. REGIME DE IRRIGAÇÃO E DENSIDADES DE FRUTOS NA PRODUÇÃO DO MELÃO HIDROPÔNICO / EFFECTS OF IRRIGATION REGIMES IN YIELD HIDROPONIC MUSKMELON
Um dos fatores que influência na perda de produtividade da cultura do meloeiro é o manejo inadequado da irrigação, sendo assim, a escolha de intervalos entre irrigações é um dos pontos que ainda deve ser melhor determinado, especialmente em sistemas pouco estudados, como é o caso da hidroponia. Em função disso realizou-se dois experimentos com melo
