| There is controversy about the benefits of silicon (Si) on tomato plants. This element has structural and metabolic functions in the physiology of plants, generating benefits that may result in increased productivity of various plant species. Thus, the aim of this study was to evaluate the phytotechnical characteristics and the productivity of tomato plants according to the rates and sources of Si. The design was established in randomized blocks with factorial 3x5, corresponding to three sources of silicate (calcium silicate, potassium silicate and sodium silicate) and five doses of Si (equivalent to 0, 100, 200, 400 and 800 kg ha-1 of SiO2). The fertilization with Si increased the commercial productivity of tomato plants and reduced the occurrence of... |

| O Brasil tem condições de elevar a produção de alho a ponto de suprir a demanda interna. Para alcançar tal êxito, é necessário avaliar o maior número possível de cultivares visando estabelecer as melhores para cada região. Sendo assim, esse trabalho objetivou avaliar o rendimento econômico e a qualidade de bulbos de 20 cultivares de alho na região Centro-Sul do Paraná. O experimento foi conduzido entre os meses de março e setembro de 2009, no município de Guarapuava-PR. O delineamento experimental foi em blocos casualizados, com três repetições. Os tratamentos constituíram-se em doze cultivares de alho seminobre e oito cultivares de alho nobre. Foram realizadas as avaliações de produtividade total (PT), produção comercial (PC) e classificação comercial dos... |

| The influence of different cover crops was evaluated over the agronomic performance of tomato hybrids for industrial processing, as well as its effect over soil chemical attributes. The experimental design was completely randomized, in a split plot scheme, with four replications. Main treatments (plots) were composed of winter cover crops (oat, hairy vetch, clover and radish) and of a fallow area (spontaneous vegetation). Subplots were composed of four processing tomato hybrids (AP529, AP533, Kátia and Sicílio). We evaluated the total production (TP), marketable production (CP), average mass of marketable fruits (AMCF) and number of marketable fruits (NCF). Chemical analysis of soil was done in two stages: one week preceding implantation of cover crops and... |

| ABSTRACT Dormancy in lettuce seeds is a process not yet fully understood. High storage temperatures can cause seed dormancy promoting physiological and enzymatic changes. The goal of this study was to investigate the influence of storage period and environments on the quality and dormancy of different lettuce cultivars. We also investigated the biochemical changes. A completely randomized experimental design was used in a 4x8x3 factorial arrangement to evaluate physiological quality on different storage periods (30, 60, 90 and 120 days) and environments (15, 25 and 35°C) of seeds from eight lettuce cultivars (Everglades, Babá de Verão, Elisa, Luiza, Grand Rapids, Hortência, Salinas 88 and Rubete). The biochemical activity was accessed by tetrazolium test... |
