Advancing Greenhouse Tomato Quality: A Comprehensive Review of Recent Research

Greenhouse cultivation ensures year-round tomato production. However, optimizing key fruit quality attributes is still challenging. Current practices often fail to achieve the desired sensory and nutritional profiles, necessitating a systematic review of innovative regulation techniques. This review aimed to bridge this gap by offering a comprehensive summary of recent advances in techniques for regulating the quality of greenhouse tomatoes. These include cultivar selection (cultivars with varying sensory, flavor, and nutritional qualities) and advancements in breeding technologies (molecular marker-assisted selection and gene editing), regulation of environmental factors (light, temperature, humidity, and CO₂ concentration), and agronomic practices (irrigation, fertilization, and other management measures). Moreover, the multifactor synergistic regulation of tomato quality has been discussed. Finally, the prospects for optimizing quality control strategies in greenhouse tomato production, as well as the strengths and limitations of emerging technologies, have been discussed to guide future technological innovations.
