Effect of cabbage and soybean seed storage at elevated partial pressure of oxygen on germination behaviour and seedling quality. Seeds were stored for 4 weeks at 5 % RH, either at ambient air conditions (open symbols) or in steel tanks with 18 MPa oxygen (closed symbols). (A) Effect on total germination for the most- (triangles) and the less-mature (squares) cabbage seed fractions. (B) Effect of storage conditions and period on the rate of germination (T50) for the two cabbage seed fractions. (C) Effect of storage conditions and period on the speed of germination (T50) for the soybean seeds (circles). (D) Seedling quality of control soybean seeds after 4 weeks of storage under ambient conditions (32 % RH, 20 °C and 0·1 MPa air). (E) Soybean seedling quality after 4 weeks storage at 18 MPa oxygen, 5 % RH and 20 °C. Error bars represent the standard error in the germination assay with three replicates of 50 (cabbage) or 25 (soybean) seeds.
