All seeds were germinated at 27 °C (n = 5 per condition).Within each column, values followed by different letters are significantly different (P < 0.05). Within each row, the significance of differences between control and heat-stressed seeds is shown according to Student’s t-test (P < 0.05*, P < 0.01**, and P < 0.001***). SD values are shown after T₅₀ values.
