Fritillaria (Liliaceae). This genus germ. primarily at 40. Sometimes this had to be preceded by a cycle at 70 making the species a 70-40 germinator. The seedlings did not always develop, and it is probable that this was the result of shifting them to 70 too suddenly. More study is needed on this problem. Some species showed intolerance to DS, particularly F. pudica germ. best in outdoor treatment (36% in April) and less in 40-70- 40(20% in 2-9 w). Germination failed when sown at 70.
