Postharvest losses in quantity and quality of tropical and subtropical fruits are commonly very high, especially as many of these fruits are produced in developing countries and transported long-distance to markets in developing and developed countries. Due to high moisture content, active metabolism, and tender texture, significant losses resulting in senescence, softening, physiological disorders, mechanical injuries, and microbial spoilages occur at any point from harvest through utilization. To reduce these losses, understanding the causes of deterioration in tropical and subtropical fruits is the fundamental step and followed by utilizing appropriate and affordable technological procedures to slow softening process, improve flavor quality, enhance nutritional quality (vitamins, minerals, dietary fiber, and phytonutrients including carotenoids and phenolic compounds), reduce browning potential, decrease susceptibility to chilling injury, and/or increase resistance to postharvest decay-causing pathogens.

It is a special issue to present and discuss the factors involved in ripening, senescence, and deterioration of harvested tropical and subtropical fruits and the postharvest technologies to restrict loss and ensure the maximum quality value. The objective of this special issue is to introduce the state of the art for the most relevant problems in tropical and subtropical fruits after harvest and to emphasize the effective, safe, and environmentally-friendly technologies involved in postharvest handling of these fruits. It is expected to address and report recent advanced topics in postharvest tropical and subtropical fruits and their storage techniques in both academic researches and real world application. Researches and applications in tropical and subtropical fruits and their storage are especially encouraged to be submitted to this special issue to present the latest research and development in this fast growing field.

Potential topics include but are not limited to the following:

• Postharvest ripening and senescence physiology, biology, and technology of tropical and subtropical fruits
• Physiology, biology, and mitigation technologies for postharvest chilling injury in tropical and subtropical fruits
• Causes of postharvest decay and losses in tropical and subtropical fruits
• Novel postharvest treatments and technologies to reduce losses and maintain quality in tropical and subtropical fruits and vegetables, such as CA and MA storages, ethylene, 1-MCP, temperature conditioning, and chemical and nonchemical treatments
• Biological control and host defence elicitors during tropical and subtropical fruits
