Effect of seed priming on germination of common bean (Phaseolus vulgaris L.) under drought stress

The aim of this study was to determine the effect of hydropriming (dH2O ; PT1) and osmopriming (-0.8 MPa PEG ; PT2) on germination of two common bean cultivars ('Biser' and 'Trešnjevac') under induced drought stress. The germination capacity was tested on the germination paper soaked with dH2O (T1) and -0.6 MPa PEG (T2) for nine days. The results showed that there was no significant difference between two common bean cultivars in terms of germination success, but there were significant differences between pretreatments (PT1 and PT2) and treatments (T1 and T2) in terms of germination success for these cultivars. Seeds of both cultivars germinate significantly faster on dH2O (T1) when pretreatment is PEG -0.8.MPa (PT2), but dH2O (PT1) is a better seed priming technique to use under induced drought stress (-0.6 MPa PEG ; T2).
