Figure 7.

Effect of TG levels on GR activity in shoots and roots of maize seedlings. The values for TG were taken from Figures 1 and 4, and those for GR activity were taken from Figures 2 and 5. The TG levels were manipulated by treatment with different concentrations of the herbicide safeners CGA 154 281 and BAS 145 138 (square) or simultaneous treatment with 5 μm each of two herbicide safeners and different concentrations of BSO (triangle). Controls (circle) were cultivated on nutrient solution without additions.
