Viburnum (Caprlfollaceae). Viburnums divide into two groups. The first group germ. in a 40-70 pattern. The cotyledons develop within a week or two after germination. This group is adapted to germination in spring and immediate leaf development and growth. The second group germ. in a 40-70-40 pattern with extension into a 40-70-40-70-40 pattern. Germination takes place in a cycle at 40. The seedlings must be kept at 40 for two to three months after radicle development is complete in order for the cotyledons to develop properly on shifting to 70. Puncturing. the seed coat had no effect in three species. All seed was WC for 1-2 w. Germination was stimulated by GA-3 in V. burkwoodi is a 40-70 germinator. Fresh seed or seed DS 6 m at 70 or 40 germ. 40-70(75-80% in 5-10 w) and 70(none). The cotyledons develop within a week or two after radicle emergence. Grinding a hole through the seed coat had no effect: Fresh WC seed germ.. similarly, but seed collected in February gave lower germination.
