Prince Edward Island Potatoes Prince Edward Island Potatoes (also known as PEI Potatoes) refers to the brand and geographic identifier for potatoes grown and packaged in Prince Edward Island, a Maritime Province on the Atlantic coast of Canada. In a similar fashion to potatoes grown in other parts of North America (such as Idaho), Prince Edward Island Potatoes are marketed and trademarked as being grown in the unique growing conditions and climate of Prince Edward Island. Prince Edward Island's growing conditions are characterized by warm summers, relatively cold winters, significant natural precipitation, and a unique red
Climate change and potatoes concentrations in the atmosphere. The major benefit of increased atmospheric carbon dioxide for potatoes (and other plants) is an increase in their photosynthetic rates which can increase their growth rates. Potato crop yields are also predicted to benefit because potatoes partition more starch to the edible tubers under elevated carbon dioxide levels. Higher levels of atmospheric carbon dioxide also results in potatoes having to open their stomata less to take up an equal amount of carbon dioxide for photosynthesis, which means less water loss through transpiration from stomata. As a result, the water use efficiency (the amount of carbon assimilated
