Researchers take a look at the versatile L.: wanton weed and/or golf turf?

Abstract

Poa annua L. (annual bluegrass) is seen by researchers as both a troublesome' weed, especially on golf courses, and as an attractive turf. A wealth of genetic variations in the morphological, physiological and life history characters of this weedy species has been detected. Awareness of the genetic differences in growth habit and reproductive strategies between annual and perennial biotypes of P. annua can be helpful in managing it as turf, as well as in situations where it is treated as a weed.
