The most important sown temperate grasses are Lolium, Festuca, Dactylis, Phleum, and Bromus. Temperate regions

The regions between the Arctic Circle and the Tropic of Cancer, in the northern hemisphere, and between the Antarctic Circle and the Tropic of Capricorn, in the southern hemisphere. In terms of agriculture, there are just the two regions of temperate and tropical, although many people also recognise the subtropics. Tropical regions are characterised by short days and freedom from frost. Temperate regions have freezing, short-day winters, as well as warm, long-day summers. The crops of each region are profoundly different, although a few tropical annuals can be grown in a temperate summer (e.g., tomatoes, tobacco). See also: Day-length.
