However, it should be noted that all treatments resulted in a highly significant decrease ( p < 0.001) in the glycine content in comparison to the control, from an initial value of 3.48 μmol g −1 dw in the control and a decrease to an average value of 0.19 μmol g −1 dw with the T22, BP + T22 and BP + 6PP applications ( Table 3 ).
