Fig. 4. Relationship between standard germination or accelerated-aging germination and mean daily maximum temperature during soybean seed filling (growth stage R5–R7) for Hutcheson. Only those seed lots that showed no evidence of seed infection by Phomopsis longicolla in the standard germination test were included (n = 12) and regression models for standard germination (Y = 135.551 – 1.409X, P = 0.05) and accelerated-aging germination (Y = –724.794 + 60.952X – 1.126X2, P = 0.01) were significant. Data from irrigated experiments are identified with an asterisk.
