Tobacco (Nicotiana tabacum L.) plantlets were transferred into pots with Perlite initially moistened either by water or 50 A mu M ABA solution and they were grown under low (LI) or high (HI) irradiance of 150 and 700 A mu mol m(-2) s(-1), respectively. Endogenous content of ABA in tobacco leaves increased considerably after ABA application and even more in plants grown under HI. Stomatal conductance, transpiration rate and net photosynthetic rate decreased considerably 1 d after ex vitro transfer and increased thereafter. The gas exchange parameters were further decreased by ABA application and so wilting of these plants was limited. Chlorophyll (a+b) and beta-carotene contents were higher in ABA-treated plants, but the content of xanthophyll cycle pigments was not increased.
