EnglishHardening by abscisic acid of tobacco plantlets grown in vitro.

Klíčová slova: ex vitro transfer, in vitro hardening, Nicotiana tabaccum, stomatal conductance, adaxial and abaxial epidermes
Abstrakt: Abstract Tobacco planflets were grown in vitro on Murashige and Skoog's medium with 2 % of saccharose. Addition of 0.01 mM abscisic acid (ABA) into the medium decreased stomatal conductance of the adaxial epidermis and especially the abaxial epidermis without negative effects on growth parameters. As a result the rate of water loss from ABA-treated plantlets taken out of cultivation vessels was slower than that of control plantlets. This could help their acclimation after transplantation to ex vitro conditions.
