Polygonatum (üiiaceae). P. humile germ. 70D(2/8 nrioth w). The radicle developed an extensive root system, but a stem and leaves did not develop until the seedling had been subjected to 40-70-40-70 (a year of alternating cycles), and the leaf and stem did not develop until the 4th w in the last cycle at 70. Probably longer times at 40 and/or 70 would hasten leaf development, but it is clear that the rate of destruction of the growth inhibitors is slow.
