Macro and Micro Element Contents of Several Oat (Avena sativa L.) Genotype and Variety Grains

Abstract

<em>In the current study, macro and microelement contents of oat grains were determined by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). P contents of grains were found between 2428.72 mg/kg (Arslanbey) and 4557.25 mg/kg (TL10). While K contents of oat samples change between 3055.99 mg/kg (TL63) and 5621.12 mg/kg (TL8), Ca contents of oats ranged from 568.50 mg/kg (TL63) to 1269.97 mg/kg (TL86). In addition, the highest and lowest Mg were determined in Kırklar (2024.88 mg/kg) and TL73 (1252.48 mg/kg) oat samples, respectively. Iron contents of oat changed between 29.98 mg/Kg (TL7) and 80.78 mg/Kg (Arslanbey). While Zn contents of oat samples change between 15.50 mg/kg (Arslanbey) and 37.68 mg/kg (TL/76), Mn contents ranged from 25.82 mg/kg (TL63) to 62.55 mg/kg (Kırklar). Also, the highest Zn and Cu contents of oat grains were found in TL76 (37.68 mg/kg) and TL67 ( 8.67 mg/kg). Locations had a significant effect on all macro and micronutrient concentrations of oat grains.The results presented here suggest that oat grains could serve as a good source of mineral elements.</em>
