What does the term "tillering" refer to in grasses?

The term "tillering" in grasses refers specifically to the formation of erect shoots or tillers. This is an essential growth characteristic in many grass species where the plant produces additional stems, or tillers, from the base of the main stem. Tillering contributes to the overall density and structure of the grass, enhancing its ability to capture sunlight and utilize resources efficiently. As grasses tiller, they become more robust and better able to compete for space and nutrients.

The process occurs after the initial establishment of the plant and is a key stage in the growth cycle that can significantly impact the yield and overall health of grass species, particularly in agricultural contexts such as pasture and forage production. By forming new shoots, grasses can maximize their biomass and establish a more dense canopy, which is crucial for preventing weeds from taking hold and for providing better forage for livestock.
