Corydalis (Fumaraceae). C. caseana ssp. brandegei germ. 70 GA-3(50%) and none in the other treatments. The seeds split in the 3rd w but it is another week or two before the radicle develops and the cotyledons do not start developing until the 10th w. A prior 4 w of OS had littie effect on the germination in 70 GA-3, but a prior 4 w at 70 was fatal.
