The accumulation of endogenous ABA and GB was affected by the exogenous application of ABA
or Flu in maize plants subjected to IR-DS. In the absence of ABA or Flu, endogenous ABA and GB
levels increased 210% and 140% in ZD958 and 190% and 90% in JD20, respectively under IR-DS.
The corresponding values in the presence of ABA and Flu were 230% and 160% in ZD958 and 210%
and 130% in JD20 for ABA level as well as 200% and 70% in ZD958 and 140% and 50% in JD20 for
GB level, respectively (Figure 2A,B).
