Fig. 7. Oleic acid concentration as a function of the date when the 100 to 300 degree-days after flowering period began at four locations where sunflower is cultivated in Argentina (see Table 2 for further information). Data from P.R.S. Peña were not continued after 22 January because sunflower is not cultivated beyond that date. Horizontal bars indicate the period during which grain filling typically occurs at each location. Oleic acid concentration was estimated using the function from Fig. 2.
