Flower bud developmental stages of D. hybrida. Stage 1 (0–5 mm), immature flower bud with light green surface; stage 2 (6–10 mm), small sized bud with light green surface; stage 3 (11–15 mm), medium-small sized bud with green adaxial surface and abaxial surface turning light purple; stage 4 (16–20 mm), medium sized bud with adaxial surface of perianth turning light purple; stage 5 (21–25 mm), medium- large bud with green adaxial surface and abaxial surface turning more purple and stage 6 (26–30 mm), large bud with purplish adaxial and abaxial surface; stage 7 (31–35 mm), mature bud with dark purple at adaxial and abaxial surface. a Bud morphology b Buds were opened and separated to show the developmental stage; c Column/anther morphology at different developmental stages.
