Rd. Cousens et al., COMMENT - NUMBER OF SAMPLE-POPULATIONS REQUIRED TO DETERMINE THE EFFECTS OF HERBICIDE RESISTANCE ON PLANT-GROWTH AND FITNESS, Weed Research, 37(1), 1997, pp. 1-4
Experiments to determine the relative growth and fitness of herbicide-
resistant and susceptible weeds commonly include only a single populat
ion of each. It is argued that such limited experimental designs can b
e misleading and should be avoided. Guidelines are given to aid decisi
ons on choice of number of populations.
