Chionanthus (Oleaceae). C. virginica germ. 50% in August in outdoor treatment after starting in November nearly two years earlier. This parallels the germination in 70-40-70 treatment but takes longer and offers no advantage. After the seeds germinate, a period of time at 40 is necessary before stem and leaf growth will occur on returning to 70. It was indicated in the 2nd Ed. that 3 m at 40 may not be long enough. The optimum has not yet been determined, but it has been found that seedlings that had not developed sterns and leaves after 3 m at 40 and a shift to 70 would do so after 3 m at 70, a second 3 m at 40, and a shift to 70.
