Abstract

Laboratory studies were conducted to determine if electrolyte leakage fromeither leaf tissue, germinating seeds, or excised roots correlated with previously established soil-applied field response of soybean cultivars and target weeds to sulfentrazone. Sulfentrazone-induced electrolyte leakage from leaf tissue of coffee senna (sensitive), sicklepod (tolerant), and soybean cultivars 'Asgrow 6785' and 'Carver' (sensitive) and 'Stonewall' and 'DPL3606' (tolerant) was monitored over time. Electrolyte leakage from leaf tissues, caused by 25 ppm (65 muM) sulfentrazone, agreed directly with the known response of these weeds, but response of the four soybean cultivars wasequivalent. Furthermore, sulfentrazone-induced electrolyte leakage from leaf tissue of Asgrow 6785 and Stonewall was not affected by sulfentrazone concentration as high as 100 ppm (258 muM) nor by light intensity (4 and 120 mu mol/m(2)/s photosynthetically active radiation). For germinating seeds, sulfentrazone-induced electrolyte leakage was also independent of soybean cultivar. In contrast, electrolyte leakage from excised roots of germinal soybean seedlings did concur directly with the previously established cultivar sensitivity to soil-applied sulfentrazone. Results indicate that electrolyte leakage from excised roots of soybean germinal seedlings can be used toassess cultivar sensitivity to soil-applied sulfentrazone.
