All lines were in the Landsberg erecta background. RL, Rosette leaves; CL, cauline leaves; TL, total no. of leaves. Values are the means ± 2 se (i.e. within a 95% confidence interval). n > 10 plants.
a
These plants did not bolt and rosette and cauline leaves could not be distinguished.
b
ga1-3 plants did not flower in short days.
