Dianthus (Caryophyllaceae). Twenty species were found to be D-70 germinators with only D. superbus alba germ. 70L(97% in 3-5 d) and 70D(71% in 5-9 d). The remaining seeds from the 70D treatment were shifted to 70 whereupon 20% germ. on the 4th d. jt is likely that the seeds require light for germination when fresh and that the light requirement dies off on DS.
