STUDIES ON THE POSSIBILITY OF COMPARING GRAIN PROTEIN CONTENT OF OAT CULTIVARS BY AERIAL INFRARED PHOTOGRAPHY

Abstract
Optical densities from aerial infrared photographs of foliage of 11 (initially 50) field-grown oat cultivars could not be reliably used to distinguish cultivars with different protein content. Optical densities varied between replications and years; cultivars, however, maintained their relative high and low levels of protein over years and replications. Results from regression and canonical analysis largely failed to show a relationship between optical density and protein content.Key words: Oat protein, aerial photography
