Temperature variation is a main factor for growth and development of eustoma (Eustoma grandiflorum) seedlings. The study was aimed to investigate different day and night temperatures i.e., T0, 20°C day/18°C night (control); T1, 10°C day/8°C night (low) and, T2, 25°C day/20°C night (high) for characterizing the morpho-physiological attributes of eustoma seedling in greenhouse. At 20°C day/18°C night temperature condition, eustoma seedling developed easily in greenhouse. In case of 25°C day/20°C night temperature induced the rosetting in eustoma seedlings. Besides, seedling growth and development was stuck in low (10°C day/8°C night) temperature condition. According to this low and high temperature condition, significant variation of stomatal conductance, SPAD value and leaf area was observed on eustoma seedling compared with 20°C day/18°C night (control) temperature. The results show that 20°C day/18°C night temperature significantly influenced the eustoma seedling growth and development, but high temperature caused the rosette of seedling.
