Mimulus (Scrophulariaceae). Light was required for some species. M. "Andean Nymph" germ. 70(1%)-40-70 and 40(34% in 5th w). M. "Calypso hybrids" germ. some in the 10th w at 70. M. ringens required either light or GA-3 for germination. Fresh seed germ.. 70D GA-3(100%.in 2nd w), 70L(15% in 1-5 w), and 70D(none). A prior 3m at 40 had no effect. If either fresh seed or seed DS 6 m at 70 were subjected to three to four cycles starting at 40 and 70 and then shifted to 70L, 90-100% germ. in the 2nd w. Shifting seed in 70L to 70D GA-3 caused the rest to germinate in the 2nd w.
