The time course of stem elongation had a typical sigmoidal
growth pattern for all the thermal regimes (Fig. 4A). Under RT,
the main flower stem reached the maximum length of 65.6 cm at
189 DBT (Fig. 4A; Table 2). The rate of stem elongation changed
throughout the growing cycle and it was maximum at 120 DBT,
with Vmax = 0.80 cm d−1 (Fig. 4B; Table 2). The first flower bud of
the inflorescence appeared at 127 DBT. Anthesis started at 161 DBT
