Seeds were sown and allowed to germinate in the dark for 4 d in a growth chamber at 20°C. Seedlings were then exposed to an additional 3 d of continuous CW, R, FR, or allowed to remain in DD. Coleoptile lengths were measured from the point of attachment of the scutellum to the tip. Seedling height was measured from the attachment of the scutellum to the tip of the primary leaf. Leaf opening was measured as the width of the blade in mm at the broadest point of the leaf. Significance was established by analysis of variance.

a

Significant at P = 0.01. 

b

Significant at P = 0.05.
