Özet

The research was conducted to determine the properties of gibberellic acid pre-treatments that reducing the negative effects of salt stress on the seeds germination of triticale (x Triticosecale Wittmack) plant under salt stress. In the study, four different gibberellic acid (0, 100, 200 and 300 ppm) and salt applications at 0, 50, 100 and 200 mM (NaCl) concentrations, a factorial experiment was conducted in completely randomized design (CRD) with four replications, In research, germination power (%), germination rate (%), germination index (%), average germination time (days), sensitivity index (%), root length (cm), stem length (cm), root fresh and dry weight (mg), shoot fresh and dry weight (mg) values were examined. According to the result of the research; when the salt concentrations increase, the germination and growth parameters of triticale were inhibited. It was seen that increasing doses of gibberellic acid pre-treatments have significant and positive effects on the germination and growth parameters of triticale seeds under salt stress. The best germination properties of triticale seeds were obtained from 300 ppm giberellic acid + 0 mM (control) salt combination.
