Corydalis (Fumaraceae). Seeds of the monocarpic species ( C. nobile germ. 35% in outdoor treatment with germination occurring in February and early March from seed collected in May. The oscillating temperatures of outdoor treatment are needed not only in spring but in the preceding fall. Duringthe fall 35% of the seeds expand and split the seed coat, and it is only these seeds that germinate the following spring. Of the remaining 65% of theseeds, 20% rotted and 45% remained firm and possibly will germinate the next spring. Seeds subjected to alternating cycles give germination extending from the 4th to 8th cycles with overall germination under 20%. Seed DS 6 m at 70 is all dead. Treatment with GA-3 led to total rotting of the seeds.
