| Özet |
| In the present study, we investigated time course changes of water status including relative water content (RWC), leaf osmotic potential (ΨΠ), stomatal conductance (gs), proline (Pro), chlorophyll fluorescence (Fv/Fm) and total chlorophyll content in the Arabidopsis thaliana under PEG-induced drought stress after exogenous ABA treatment. To a better explanation for the role of ABA in the water status of A. thaliana to drought stress, wild-type (Columbia) and ABA-deficient mutant (aba2) of A. thaliana were used in the present study. Moreover, three weeks old Arabidopsis seedlings were applied exogenously with 50μM ABA and exposed to drought stress induced by 40% PEG8000 (−0.73MPa) for 6h, 12h and 24h (hours). Our findings indicate that RWC of wild-type and aba2 started to decrease in the first 12h and 6h of PEG-induced drought stress, respectively. However, exogenous treatment of 50μM ABA increased … |
