The term pedicel/peduncle is used to define the floral stem for either true flowers or the flowers bearing ectopic flowers or inflorescences. A floral-like structure terminated by a gynoecium is considered a flower(Bowman et al., 1993).

Each value represents the mean±s.d.

Ectopic floral-like structures generated from the floral meristems at basal positions of the main inflorescences usually developed like secondary inflorescences.

§

In our culture conditions, 35S::SOC1 inflorescences terminated after producing less than ten flowers.
