Seed Germination Theory and Practice, 2nd ed. — N. C. Deno, 1993 · Ch. 20, Anemone p. 94Public domain Show the original text Anemone (Ranunculaceae). This genus divides into two groups. The .first group are early spring bloomers with hairless seed coats, multicycle germination patterns, and intolerance of OS. The second group are taller and bloom in summer and fall, the seed is embedded in cotton in a spherical cluster, and germination is largely D-70 with curious differences between DS seed and fresh seed. A. cylindrica seed must be DS 6 m at either 70 or 40 after which germination is 100% over 3 m when sown at 70. If fresh seed is sown at 70, germination is zero. Curiously the difference between DS and fresh seed is not so great when the seed is sown at 40. The patterns were 40(78% over 3 m)-70(20% over one rn) for DS seed and 40-70(76% over 3 m) for fresh seed. Seed Germination Theory and Practice, 2nd ed., Ch. 20, Anemone p. 94. Quoted exactly. Every value on this card comes from this record, except the difficulty rating, which is ours; the step names come from a fixed list. Protocol 2 N. C.
