I think that every plant reacts the same to foliar application of ABA.

Mechanism:

ABA close stomata pores. It requires a reversal of ion fluxes, i.e. outflow of Cl-, NO3- and malate (with a reconversion of malate to starch), which depolarises the plasma membrane and causes K+ to exit through voltage-gated channels, with consequent loss of water, and closure of the stomata. This occurs through channels of the SLAH/SLAC, ALMT and CLC families, and is induced by lack of light, circadian rhythm and ABA perception.

In general, plants under abiotic stress conditions respond favorably to foliar application of ABA. In sugarcane, it has been reported to improve drought tolerance. Like sugarcane, maize also belongs to grass family, and has the same photosynthetic efficiency as the C4 plant. Maize is, therefore, expected to behave similarly.
