Table I. Seedling responses to EOD-FR treatments in a panel of genetically diverse maize inbreds.

Maize inbreds are grouped based on population structure. Limited seed availability for Tzi8, combined with poor germination, contributed to reduced statistical power in analyzing this line. C, Control; INC, significant elongation increase over control treatment; NS, nonsignificant difference between the two treatments based on Student’s t test (* P < 0.05, ** P < 0.01, *** P < 0.001); NSS, temperate nonstiff stalk; SS, temperate stiff stalk.
