The influence of cultivation conditions on total antioxidants content in barley grain and its yield ammount

In order to establish the influence of climatic conditions on the total antioxidants content (TAC) in grain, barley samples were grown for three years in three geographical points of the Krasnoyarsk Region and the Republic of Khakassia: Krasnoturansky, Beisky and Shirinsky State Varietal Site (SVS). The research objects were 4 hulled and 1 hull-less barley samples: Acha, Biom, Buayn, Krasnoayrsky 91 and Omsky golozerny 1. To determine the TAC in the grain, 2 solvents were used-bidistilled water or 70 % ethanol. The measurement was performed on the device "Color Yauza-01-AA". Gallic acid was used as a comparison sample. In parallel, the production characteristics of barley were measured: 1000 grain weight, the duration of growing season and the yield. The extraction methods used showed almost the same results. It was shown that the levels of TAC in oat grain grown in different geographical locations had not differed significantly from each other. Hulled samples formed grain with the same level of TAC as hull-less...
