Polygonatum (Iiliaceae). The three species germ. hypogeally at 70 and form only a corm and branching root system at 70. When development of this is complete, the seedlings were shifted to 40. It was found that 3 m at 40 was insufficient to destroy growth inhibitors in the epicotyl. A 6 m period at 40 and a shift to 70 initiated stem and leaf formation in P. biflorum seeds collected in October, WC 7 d, and placed outdoors germ. 90% in May-June. None germ. in 70L, 70D, or 40-70.
