Aquilegia (Ranunculaceae). Three treatments gave germination, and all other treatments failed. The three were (a) treatment of fresh or DS seed with GA-3 at 70, (b) sowing of OS seed at 70, and (c) outdoor treatment. All three of the treatments were used In only a few of the species so that it is not certain that all three will work with every species. Stewart and Presley (ref. 9) were the first to report that GA-3 was valuable in stimulating the germination of A. saximontana germ. 70 GA-3(86%, 3rd w), 70(none), and 40-70(15%, 2nd w).
