The sizes of various organs were measured to the nearest millimeter, and the number of organs was counted in dwf1-1 and wild-type plants grown individually in 5.5-cm pots. Each value represents the mean of 10 or more plants ± se.
a
Maturity is considered to be the cessation of new flower development.
b
nd, Not determined.
c
Measured from the second leaf pair.
d
Number from the primary inflorescence.
e
Number from the entire plant.
