Description	Stomatální a nestomatální působení kyseliny abscisové při otužování rostlin. (cs) Abscisic acid (ABA) might be a suitable candidate for improvement of ex vitro transfer of micropropagated plantlets. It could be applied either into the substrate immediately after ex vitro transfer or into the medium for the last subculture. Content of endogenous ABA increased considerably after ABA application and it further increased in tobacco (Nicotiana tabacum L. cv. SR1) plants grown ex vitro under higher irradiance (700 vs. 150x10-6 mol m-2 s-1) showing occurrence of stress in these plants. After ex vitro transfer, stomatal conductance and transpiration rate decreased more in 5x10-5 M ABA-treated plants than in control plants and so their wilting was limited. Higher contents of chlorophylls and carotenoids, and decreased degree of deepoxidation of xanthophyll cycle pigments also suggested less stress in ABA-treated plants. Changes in antioxidative enzyme activities were also observed. For in vitro hardening, much lower ABA concentration should be used as 5x10-5 M ABA caused considerable ret...
