1. Agronomic biofortification with iodine in lettuce plants cultivated in floating hydroponic system
ABSTRACT Iodine is essential to human metabolism, being fundamental in the production of the thyroid hormones. The consumption of biofortified foods can contribute to the increase of its intake. The objective of this study was to increase the iodine concentration in lettuce, also evaluating its effects on plant growth and production. The experiment was condu

2. Water and physiological relationships of lettuce cultivated in hydroponics with brackish waters
RESUMO As necessidades da racionalização do manejo de águas salobras em cultivos hidropônicos constituem-se formas de ampliar e gerir a oferta hídrica em regiões de escassez. Neste sentido, este trabalho foi realizado com o objetivo de avaliar as relações hídricas e fisiológicas da alface americana (cv. Tainá) em plantas expostas a estratégias de

3. Produção orgânica de alface americana fertirrigada com biofertilizantes em cultivo protegido / Organic yield of iceberg lettuce fertigated with biofertilizers, in organic protected cultivation
Biofertilizers have positive effects on nutrition, postharvest attributes and crop protection, but little is known about its characteristics and real efficiency. Furthermore, application rates commonly used throughout the crop cycle does not attend the growing culture needs satisfactorily. Thus, this study aimed to evaluate the effect of biofertilizers appli

5. Tratment evaluation with ozone water for iceberg lettuce sanitization / Avaliação do tratamento com agua ozonizada para higienização de alface (Lactuca sativa)
A etapa de sanitização é critica e de suma importância para a qualidade microbiológica de vegetais. É importante que o sanitizante seja além de eficaz, seguro do ponto de vista toxicológico. O uso do ozônio durante o processamento de vegetais prolonga a vida de prateleira, preserva os atributos sensoriais e não produz resíduos tóxicos. O objetivo

6. Evaluation of ozone efficiency as a sanitizer on minimally processed vegetables. / Avaliação da eficiencia do ozonio como sanitizante em hortaliças folhosas minimamente processadas.
Minimally processed fruits and vegetables are sold already washed, peeled, cut or sliced, sanitized, packaged and cold-storaged. Consumption of this kind of food has increased markedly in the last decades due to people interest for fresh and practice foods. High handling during its processing, increasing of its shelf-life and absence of remarkable technologi

7. Resistência genética, fungicidas e solarização para o controle de Thielaviopsis basicola (Berk. &Broome) Ferraris na cultura de alface (Lactuca sativa L.). / Genetic resistance, fungicides and solarization for the control of Thielaviopsis basicola (Berk. &Broome) Ferraris in lettuce crop (Lactuca sativa L.).
Lettuce is the most used leafy vegetable in Brazil. Its crop is being severely affected by Thielaviopsis basicola, fungus which causes root rot and stunting in plants. There are no control studies about this pathogen for the brazillian conditions. This research aimed: to determine the T. basicola occurence in São Paulo State commercial lettuce and other lea

8. Outbreak of Shigella sonnei infection traced to imported iceberg lettuce.
In the period from May through June 1994, an increase in the number of domestic cases of Shigella sonnei infection was detected in several European countries, including Norway, Sweden, and the United Kingdom. In all three countries epidemiological evidence incriminated imported iceberg lettuce of Spanish origin as the vehicle of transmission. The outbreaks s

9. Microflora of partially processed lettuce.
Bacteria, yeasts, and molds isolated from partially processed iceberg lettuce were taxonomically classified. The majority of bacterial isolates were gram-negative rods. Pseudomonas, Erwinia, and Serratia species were commonly found. Yeasts most frequently isolated from lettuce included members of the genera Candida, Cryptococcus, Pichia, Torulaspora, and Tri

10. Plant Hormone Interaction and Phenolic Metabolism in the Regulation of Russet Spotting in Iceberg Lettuce 1
Russet spotting (RS) is a physiological disorder induced in iceberg lettuce (Lactuca sativa L.) by exposure to parts per million levels of ethylene at 5 ± 2°C. Ethylene induced phenylalanine ammonia-lyase and ionically bound peroxidase activities that correlated with development of RS symptoms. The ethylene-treated tissue had significantly higher lignin co
