Alteration of the Reproductive Patterns in Drosophila melanogaster by Effects of High Concentrations of Boron on In Vitro Cultured Medium

The objective of this study was to evaluate the effects of boron (B) using as a biological model Drosophila malanogaster. Analizing specifically the responses over descendency to doses of 6,0 and 12 mg/L, comparing a control group which culture medium was prepared with water with boron concentration...
