Boron content of 16 Turkish hazelnut (Corylus avellana L.) cultivars were determined by using inductively coupled plasma optical emission spectrometry (ICP-OES) and Azomethine H. spectrophotometric method. The results varied between 13.8 and 22.2 mg/kg. No significant difference was observed between the results by the two methods (P > 0.05). However, the difference among boron content of hazelnut varieties was found to be significantly important (P<0.01). The highest boron content was in Mincane (20-22.2 mg/kg). Results revealed that the Turkish hazelnut is a good natural source of boron. (C) 2003 Elsevier Ltd. All rights reserved.
