Plug seedlings of bell pepper(Capsicum annuum L.) were grown for 50 days in controlled environment chambers under 12 hrs per day photoperiodic condition with sixteen different day and night temperature regimes to investigate the possibility of height control. The seedlings were then transplanted to greenhouse to investigate the growth, flowering, and yield afterward. Plant height and stem length of seedlings were mainly affected by day temperature rather than night temperature. Internode elongation was suppressed by a negative DIF and was enhanced by a positive DIF even with the same average daily temperature (ADT). Leaf unfolding rate was influenced more by ADT than by DIF. Fresh and dry weights increased as ADT increased. Leaf area and stem diameter increased until temperature increased up to 24$^{circ}C$ day and night temperature and decreased above 24$^{circ}C$, The position at which the first flower was initiated was lowered as ADT increased. The first flower degeneration was not obvious up to 24$^{circ}C$ ADT but increased rapidly above 24$^{circ}C$ ADT. Seedling compactness(Dry weight per plant height :mg.mm$^{-1}$ ) was greater under -DIF than +DIF condition. In conclusion, DIF treatment was an applicable technique to control stem elongation and growth rate such as leaf unfolding rate and position at which first flower was initiated could be controlled by ADT.
