Notes:
Summary A considerable increase in groat-oil content of oat (Avena sativa L.) has been accomplished recently. The objective of this study was to determine whether physiological traits of oat plants with high groat-oil content are changed in a way that would provide the energy needed for increased groat-oil content. Growth analyses were conducted in 1987 and 1988 on 25 oat lines with low and on 25 with high groat-oil content. Three harvests were made in 1987 and six in 1988. Plot biomass, plant weight, leaf area, and leaf weight were measured at each harvest and estimates for relative crop growth rate, unit leaf area, leaf area ratio, specific leaf area, and leaf weight ratio were derived. Grain yield, groat-oil content, and groat-protein content were measured at maturity. The data were analysed by using the stepwise multivariate analysis of variance technique. The results suggest that changes in growth characteristics and increases in photosynthetic capacity provide the extra bioenergy required for synthesis of more groat oil. The groat-protein content did not change as a result of increased groat-oil content in oat.
