Vliv biotických a abiotických stresorů na vlastnosti rostlin 11.5.2005<br />

Tab. 1: Změny v ob<strong>sa</strong>hu endogenních fytohormonů (kyseliny abscisové [ng g -1 (č.hmot.)] a<br />

cytokininů [pg g -1 (č.hmot.)] při vodním stresu a následné rehydrataci. Průběh vodního stresu je<br />

charakterizován hodnotami relativního ob<strong>sa</strong>hu vody (RWC) [%]. ABA - kyselina abscisová, ΣCK -<br />

celkový ob<strong>sa</strong>h cytokininů, WS - vodní stres, RH - rehydratace.<br />
