Phytosociological survey of weed in cassava cultivation in Southwestern Bahia, Brazil

Phytosociological surveys are basis for weed management in agricultural crops. We aimed in this study to survey weed within a cassava cultivation field in the city of Vitória da Conquista, Southwestern Bahia, Brazil. The crop was grown for 18 months (from January 2013 to July 2014), with samples at 35, 70 and 105 days after planting (first year cultivation), and at 350, 385 and 420 days after planting (second...

Evaluation of antioxidant activity of Malus domestica fruit extract from Kashan area

Antioxidants are considered as the main factors in the inhibition of unwanted oxidation reactions. In this research the antioxidant potential of the fresh fruits of 4 cultivars of Malus domestica cultivated in the Kashan, Qamsar area was evaluated. The antioxidant activity of the samples were evaluated using two complementary antioxidant assays: 2,2-diphenyl-1-picrylhydrazyl (DPPH) and β-carotene/linoleic acid...
