Abstract

Temperature is a critical abiotic factor influencing plant growth, metabolic processes, and reproductive development. The present study investigates the comparative growth performance and adaptive responses of Hibiscus rosa-sinensis under different temperature regimes. Plants were maintained under controlled conditions representing low (15°C), optimal (25°C), and high (35°C) temperature ranges. Growth attributes such as plant height, leaf number, leaf area, and flower production were evaluated along with physiological indicators including chlorophyll stability and visible stress symptoms.

The findings revealed that plants grown under the optimal temperature range (25°C) exhibited significantly enhanced vegetative growth, improved chlorophyll retention, and increased flowering compared to those exposed to low and high temperatures. Lower temperature conditions resulted in reduced growth rate and delayed flowering, whereas higher temperatures induced chlorophyll degradation, wilting, and decreased floral output. Although Hibiscus rosa-sinensis demonstrated adaptive plasticity across varying thermal environments, prolonged exposure to temperature extremes negatively affected overall plant vigor and ornamental quality.

This study underscores the importance of maintaining optimal thermal conditions for maximizing growth and reproductive efficiency in Hibiscus and provides valuable insights for climate-resilient horticultural management.
