Plantago (Plantaginaceae). The curious results that some species required light and others did not may be due to the light requirement dying off on DS as found for P. virginica germ. 70L(91% in 6th w), 70 GA-3(81% in 3rd w), and none in 70D or 40-70D. A prior 6 w in 70D had no effect. Seeds DS 6 m at 70 germ. 70L(90% on 5th d) and 70D(32% in 1-5 w) suggesting that DS is eliminating the light requirement.
