- Resistance levels were indicated by the resistance factor (RF). GR50 or I50 values with different letters are significantly different at P = 0.05 significant level. Data were means of two experiments
-
a GR50, herbicide rate causing 50 % growth reduction of plants
-
b I50, herbicide concentration causing 50 % inhibition of the ALS activity
-
c RF (resistance factor) = GR50 or I50 (R)/GR50 or I50 (S)
