Abstract

Changes in the IAA and ABA contents in cucumber (Cucumis sativus L.) leaves during adaptation to drought were studied. An increase in the water-retaining capacity and heat resistance of leaves indicating the onset of adaptation occurred when the leaf growth has been already suppressed. There was a transient increase in the ABA content during the initial stage of adaptation. An increased IAA content was maintained for a longer period, throughout about two-third of the adaptation period. A second increase in the ABA content was observed before the onset of leaf permanent wilting, when IAA content already decreased. Our data suggest that not only ABA, but also IAA are involved in the development of defense responses during the adaptation to drought.
