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

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.
