Means of the variable
EM-FL phase were distinguished using the Tukey test at 0.05
probability. Furthermore, as in the currently used phenological
scale in rice by Counce et al. (2000), vegetative development
is coded as main stem V-stages, varying from V1
(first leaf is
expanded) to Vn
(flag leaf is expanded) and the date of the V3
stage (Counce et al., 2000)
