ACCase activities in the absence of ACCase herbicides in the shoots of susceptible (S) and resistant (R) populations with known ACCase mutations
Data are means ± se of two to six enzyme extractions per population and each assayed in duplicate. Means followed by different letters are significantly different at the 5% level by the lsd test. *, ACCase activities from two S populations (S1 and S2) were averaged for calculation of R/S ratios.
