Rhododendron (Ericaceae). Usually light was required for germination. A. anthopogon germ. 70L(6/8 in 4th w) and 70D(2/11 in 3rd w). The 700 sample was shifted to 70L after 4 w, but no further germination occurred. A prior 3 m at 40 was fatal. The samples were so small that the experiments need, repeating.
