These data show that the temperature rises quite reliably in the living germinating seeds, but not in the others. At least, there is often a rise in the boiled section, but delayed by several days. This is usually caused by bacterial growth on the dead peas, as can be confirmed by a terrible pong when these are emptied out. Still, bacterial respiration also releases heat, so all is not lost!
