GR activity in shoots and roots of maize seedlings cultivated at 5°C for 7 d with no chemical (circle), 1 mm BSO (square), or 5 μm each of the herbicide safeners CGA 154 281 and BAS 145 138 (triangle). Before the measurements, the seedlings were grown at 25°C for 4 d in the presence of these chemicals. Mean values of six measurements from three independent experiments ± sd are presented. Values carrying different letters are significantly different at P ≤ 0.05.
