Anemone (Ranunculaceae). A. nemorosa germ. 70-40(59% in 9th w)-70-40(15% in 11th w) and 40-70(3%)- 40(10% in 3rd w)-70-40(20% in 7th w). All rotted in OT and 70 GA-3. Germination is hypogeal and on shifting to 70 most of the seedlings develop a true leaf within a month. No further leaves develop the first year.
