Notes:
A simple and rapid method for the detection of triazine resistant plants is reported, based on chlorophyll fluorescence. Leaf discs were floated in phosphate buffer solution with and without 10−4 M alrazine for 2–4 h. Subsequently, the relative leaf chlorophyll fluorescence (LCF) was measured with a plant productivity fluorometer. Following herbicide uptake LCF in triazine susceptible plants was 2–3 times greater than in the untreated controls; no such LCF changes were observed in triazine resistant plants. Concentration and time course studies were conducted on several species having triazine susceptible and resistant biotypes. The use of this method for field extension purposes is described.
