Physiological quality of bean genotypes seeds peanut and xamego treated with fungicides and insecticides

Bean is one of the most important crops because it is a staple food. In order to control diseases and pests, the use of fungicides and insecticides in the seed treatment are efficient methods. In this sense, the aim of this study was to evaluate the effect of fungicides and insecticides on physiological quality of bean seeds. The experiment was conducted in a laboratory and greenhouse, and seeds of two genotypes of...

Gene expression and antioxidant enzymatic activity in passion fruit exposed to aluminum

The objective of this study was to investigate changes in enzymatic activity and gene expression related to antioxidant defense in two passion fruit cultivars (FB100 and FB200) exposed to aluminum. The specific activity of superoxide dismutase (SOD), catalase and ascorbate peroxidase were analyzed, in addition to their relative expression pattern. The characterization of gene expression was achieved by semi-quantitative...
