Groat phytic acid concentration (GPA) was found to be positively correlated with available soil phosphorus (ASP) in seven oat (Avena sativa L.) cultivars in 1977 and 1978. Regression of GPA on ASP indicated that the amount of GPA synthesis with increasing ASP was not significantly different among cultivars within each year but was significantly different between years. GPA concentration differed significantly among cultivars within each year and was, on the average, significantly higher for each cultivar in 1978 than in 1977. Individual cultivar GPA-ASP relationships were similarly and significantly altered by environment.
