Temperature is one of the most critical environmental factors regulating tomato (Solanum lycopersicum L.) growth, physiological processes, and yield formation. With the increasing frequency of extreme temperature events and the expansion of protected cultivation systems, effective temperature regulation has become essential for achieving stable and high-quality tomato production. This review summarizes the effects and mechanisms of temperature regulation on tomato growth, photosynthesis, reproductive development, fruit quality, and yield formation. Appropriate temperature management promotes seed germination, vegetative growth, root development, and biomass accumulation by optimizing plant metabolic activities and resource utilization efficiency. Temperature regulation also improves photosynthetic performance, antioxidant defense capacity, and nutrient metabolism, thereby enhancing plant adaptation to thermal stress. During reproductive growth, suitable temperature conditions facilitate flowering, pollen viability, fruit set, and fruit expansion, while temperature extremes can cause flower abortion, reduced fruit quality, and yield losses. Furthermore, this review discusses the physiological and molecular mechanisms involved in temperature responses, including hormonal regulation, heat shock proteins, cold-responsive pathways, and temperature-sensitive gene expression. A case study is presented to evaluate the practical effects of different temperature management strategies in greenhouse tomato production. Future research should focus on integrating intelligent environmental control systems, crop growth models, and multi-factor regulation approaches to develop precise and climate-resilient temperature management strategies for sustainable tomato production.
