Abstract : Temperature remains a significant abiotic factor influencing plant growth, development, and overall productivity. This systematic review examines the physiological responses of 30 Poaceae species to varying temperature conditions, focusing on evaluating how each species adapts to extreme thermal stress. By performing the PRISMA analysis and Checklist, relevant literature was critically analyzed to identify significant patterns and trends in plant responses. 10 selected studies were reviewed and revealed plants response including germination mean time (GMT), seed germination percentage (SGP), and bio- active compound changes. The result shows that between 20-25°C, most Poacaea species maintain growth and development, suggesting an optimal temperature range. Productivity of these species were manifested in their high seed germination percentage and lower germination mean time. Despite optimal conditions, 10 exceptional species were found to have positive affinity with extreme temperatures. 7 species exhibited cold resistance at temperatures between 5 and 15°C. This was further supported by their high SGP and GMT under these conditions. Meanwhile, 3 species were able to thrive at temperatures between 30 and 40°C, suggesting their greater heat tolerance among the species studied. Understanding these responses is essential for agricultural sustainability and climate adaptation strategies. The identification of highly adaptable species can be instrumental in developing climate-resilient crops, optimizing growth conditions, and enhancing productivity in changing environments. Additionally, certain Poaceae species may serve as bio-indicators for temperature fluctuations, contributing to environmental monitoring and ecological conservation efforts. Future research should explore genetic and molecular mechanisms governing temperature adaptability to improve breeding programs and ensure food security in the face of climate change.
