Phenological adaptation in weedsan evolutionary response to the use of herbicides? Based on a presentation at the Conference Resistance 97Integrated Approach to Combating Resistance organised by the Institute of Arable Crops Research in collaboration with the SCI Pesticides Group and the British Crop Protection Council and held at Harpenden, Herts, UK on 1416 April 1997.

Abstrakt: | 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 reflect phenological adaptations. Approaches to assessing adaptedness 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 fitness of weed species in varying environments for conclusions to be drawn concerning phenological adaptation for use in herbicide resistance management. ©1997 SCI |
