Objetivou-se avaliar produção de biomassa, acúmulo de nitrato, teores e exportação de macronutrientes das cultivares de alface Regina e Verônica, em cultivo a céu aberto e sob duas malhas termorrefletoras (Aluminet®30%-O e Aluminet®40%-O) e uma
difusora (ChromatiNet Difusor®30%), em experimento conduzido na Universidade Federal de Viçosa (MG). As malhas termorrefletoras e difusora foram instaladas em estruturas tipo telados retangulares fechados, com 2 x 4 x 36 m (altura, largura e comprimento). A semeadura foi realizada em bandejas de 200 células, preenchidas com substrato comercial, sob ambiente protegido, em 31/05/02. O transplante foi realizado em 26/06/02 e a colheita em 06/08/02, ocasião em que foram feitas as avaliações. Avaliou-se a produção de biomassa, teor de nitrato, teores e exportação de macronutrientes. ?Regina? apresentou folhas mais tenras do que a ?Verônica?, portanto mais adequadas a mercados mais exigentes, porém, com maior teor de nitrato. Considerando os aspectos quantitativo e qualitativo da produção sugere-se o uso das malhas Aluminet®40%-O e ChromatiNet Difusor®30%; todavia, deve-se ajustar adequadamente a adubação nitrogenada para que não haja acúmulo de nitrato a níveis elevados devido a restrição de luz promovida pelas malhas. Ambientes e cultivares influenciaram nos teores e quantidades exportadas dos nutrientes. Com relação à exportação de nutrientes observou-se a ordem K>N>Ca>P>Mg>S.
In this experiment we evaluated the production, accumulation of nitrate, content and exportable mineral nutrient (N, P, K, Ca, Mg e S) of lettuce cultivars Regina and Verônica cultivated under two thermo-reflective screens (Aluminet®30%-O and Aluminet®40%-O), and a diffusive screen (ChromatiNet Difusor®30%). The trial was carried out in Viçosa, Minas Gerais State, Brazil. Seeds were sown in trays of 200 cells, under protected atmosphere, on 05/31/ 02. The transplant was accomplished on 06/26/02 and the harvest on 08/06/02, when the evaluations were performed. The thermoreflective and diffusive screens were installed in structures type ?shut rectangular fence?, with 2 x 4 x 36 m (height, width and length), close to the cultivation under open sky (control). We evaluated the production of mass, content of nitrate, content and exportable mineral nutrient (N, P, K, Ca, Mg e S). ?Regina? presented more tender leaves than the ?Verônica?, therefore being more appropriate to the high quality demanding markets, even so, with larger content of nitrate. Considering the quantitative and qualitative aspects, the Aluminet®40% and ChromatiNet Difusor®30% screens should be recommended; though, the nitrogen should be adjusted to avoid the accumulation of nitrate. The growing conditions and cultivars influenced content and exportable mineral nutrients. With relation to the export of nutrients the following order was observed: K>N>Ca>P>Mg>S.

The aim of this study was to investigate the molecular mechanisms underlying drought acclimation in coffee plants by the identification of candidate genes (CGs) using different approaches. The first approach used the data generated during the Brazilian Coffee expressed sequence tag (EST) project to select 13 CGs by an in silico analysis (electronic northern). The second approach was based on screening macroarrays spotted with plasmid DNA (coffee ESTs) with separate hybridizations using leaf cDNA probes from drought-tolerant and susceptible clones of Coffea canephora var. Conilon, grown under different water regimes. This allowed the isolation of seven additional CGs. The third approach used two-dimensional gel electrophoresis to identify proteins displaying differential accumulation in leaves of drought-tolerant and susceptible clones of C. canephora. Six of them were characterized by MALDI-TOF-MS/MS (matrix-assisted laser desorption-time of flight-tandem mass spectrometry) and the corresponding proteins were identified. Finally, additional CGs were selected from the literature, and quantitative real-time polymerase chain reaction (qPCR) was performed to analyse the expression of all identified CGs. Altogether, >40 genes presenting differential gene expression during drought acclimation were identified, some of them showing different expression profiles between drought-tolerant and susceptible clones. Based on the obtained results, it can be concluded that factors involved a complex network of responses probably involving the abscisic signalling pathway and nitric oxide are major molecular determinants that might explain the better efficiency in controlling stomata closure and transpiration displayed by drought-tolerant clones of C. canephora.
