INTRODUCTION Rising atmospheric CO2 concentrations, primarily driven by human activities, contribute to global Barley Strawberries (Fragaria × ananassa) warming and altered climatic patterns. represent a quintessential fruit in global Concurrently, elevated temperatures directly agriculture, appreciated for their vibrant color, influence plant physiology, metabolism, and fruit sweet flavor, and nutritional richness. However, development processes. These environmental the physicochemical and nutrient properties of factors collectively shape the physicochemical strawberries are intricately linked to characteristics and nutrient composition of environmental conditions, including atmospheric strawberries, ultimately influencing their sensory carbon dioxide (CO2) concentrations and attributes, shelf life, and nutritional value. temperature levels. As climate change continues to alter the Earth's atmosphere, understanding the Given the economic importance and widespread impact of elevated CO2 and temperature on cultivation of strawberries, elucidating the effects strawberry quality becomes increasingly crucial of elevated CO2 and temperature on fruit quality is for sustainable fruit production. paramount.
