Morphometric analysis of inflorescence phytoliths produced byAvena sativa L. andAvena strigos schreb

Morphometric analysis, the study of measurements of size and shape, has the potential to be an effective tool for phytolith analysis. This study reports the first attempt to apply the methodology to oats. In particular, this study was designed to determine if morphometric analysis could adequately discriminate between phytoliths produced in the inflorescence bracts of two species of oats, Avena sativa L. and Avena strigosa Schreb. Results indicate that while the taxa produce the same types of phytoliths, those phytoliths have significantly different measurements of size and shape. This suggests the technique has the potential to become a powerful research tool for investigators working in the wide variety of disciplines that utilize phytolith analysis.
