ABSTRACT Agrobiodiversity is essential for a sustainable food production, and the knowledge of the potential characteristics of landrace seeds may prompt farmers to adopt the habit of seed conservation for this species. This study aimed at categorizing landrace and commercial common bean (Phaseolus vulgaris L.) accessions, according to the physiological quality (viability and vigor) of seeds produced in the field, during two growing seasons, under organic and conventional farming systems. Germination percentage, field emergence, electrical conductivity, accelerated aging, cold test and seedling length were assessed. The landrace bean accessions exhibit diversity in the physiological seed quality, in terms of their viability and vigor. No differences were observed between the farming systems, in relation to the physiological quality of the seeds produced. The categorization of landrace common bean accessions allows to identify those with superior physiological seed quality.

The aim of this study was to assess the microbiological profile of leafy vegetables from organic and conventional farming (n=70). The microbiological parameters analyzed consisted of aerobic mesophilic bacteria, yeasts and molds, coliforms at 30 and 45°C, and Salmonella ssp. A biochemical identification of the Enterobacteriaceae species was carried out. Some Enterobacteriaceae species were identified in the produce from both farming systems and Hafnia alvei was the most widespread specie observed. Salmonella spp. was not detected in the samples analyzed. The microbial counts for indicator microorganisms were, in general, higher for conventional leaves when compared to those produced by organic farming.
