✦ Synopsis
The possibility of phenological adaptation in weed species is discussed in terms of an evolved response to herbicide use. Weed populations often exhibit heritable variation in life history traits that may reÑect phenological adaptations. Approaches to assessing "adaptednessÏ are discussed. Selection for seed dormancy in a grass weed is considered through life history analysis. It is concluded that too little is known about both life histories and Ðtness of weed species in varying environments for conclusions to be drawn concerning phenological adaptation for use in herbicide resistance management.
