Fig. 3. Predicted vs. observed values of main stem Haun Stage in rice using the three leaf appearance rate (LAR) models [Streck; Wang and Engel (WE); phyllochron]. Data are pooled for two rice cultivars (IRGA 421 and EPAGRI 109) sown on two dates in a paddy rice field at Santa Maria, RS, Brazil, during the 2006–2007 growing season. Panels a, b, and c are data when the simulation started at emergence. Panels d, e, and f are data when the simulation started at the day of first observed Haun Stage. The solid line is the 1:1 line.
