Fig. 5. Linear relationship between GI of grains harvested 12 d after physiological maturity (GI_12DAPM) and incubated at 20°C, and mean air temperature occurred between anthesis and PM for Quilmes Palomar cultivar sown on nine dates in 1996, 1997, and 1998. Regression equation: GI_12DAPM = 8.7 x T_mA-PM - 135.2 (r² = 0.63, P < 0.05, n = 9). Vertical bars indicate SE.
