Abstract

Evidence is presented which confirms the inhibitory action of the synthetic auxin, NAA, on stomatal opening.

In contrast to the natural auxin IAA, NAA exerts effects which, in some respects, resemble those of ABA. The mode of action of NAA on the guard cells is, however, thought to be different from that of ABA.

When NAA and ABA are applied together, their combined action results in a greater reduction in stomatal aperture than would be predicted from their separate effects.
