1. Influence of arbuscular mycorrhizal fungi, cultivation systems and postharvest parameters in the concentration of steviosides and development of Stevia Rebaudiana (BERT.) Bertoni / Influencia de fungos micorrizicos arbusculares, sistemas de cultivo e parametros pos-colheita na concentração de esteviosideos e desenvolvimento de Stevia rebaudiana (BERT.) Bertoni
Stevia rebaudiana, a shrub mostly interesting for its production of steviosides, was the object of this work. In regard to its productive chain, further researches must be done, not only in agronomical aspects, but also in the utilization of mycorrhizal fungal species, as well as in the post-harvest processes, namely the drying one. The present work aimed at

2. Ambiencia para morangueiro, em hidroponia, para a produção na entressafra e bambu como elemento construtivo para casa de vegetação / Environmental control for out-of-season production of strawberry in hydroponics, and bamboo as a constructive element for greenhouses
O uso da tecnologia do cultivo protegido e hidroponia no Brasil para a produção de hortaliças e plantas ornamentais passou por diversas fases de adaptação, visando sempre a atender às necessidades de oferta e qualidade dos produtos com a preocupação de se minimizar os custos de produção e os efeitos negativos do clima. A grande maioria destas adapt

3. Production of Vesicular-Arbuscular Mycorrhizal Fungus Inoculum in Aeroponic Culture †
Bahia grass (Paspalum notatum) and industrial sweet potato (Ipomoea batatas) colonized by Glomus deserticola, G. etunicatum, and G. intraradices were grown in aeroponic cultures. After 12 to 14 weeks, all roots were colonized by the inoculated vesicular-arbuscular mycorrhizal fungi. Abundant vesicles and arbuscules formed in the roots, and profuse sporulatio

4. Sheared-Root Inocula of Vesicular-Arbuscular Mycorrhizal Fungi †
For efficient handling, vesicular-arbuscular mycorrhizal fungi should be processed into small and uniform inocula; however, processing can reduce the inoculum density. In this article we describe the preparation and use of sheared-root inocula of Glomus spp. in which inoculum densities were increased during processing. Our objectives were to determine inocul

5. Contamination of Ammonium-Based Nutrient Solutions by Nitrifying Organisms and the Conversion of Ammonium to Nitrate.
Conversion of ammonium to nitrate and contamination by nitrifying organisms are often assumed not to be significant in ammonium-based nutrient solutions. To assess this assumption, maize (Zea mays) and pea (Pisum sativum) were grown under greenhouse conditions in aeroponic, hydroponic, and sand-culture systems containing 2 mM ammonium chloride as the sole ni
