The Impact of Salt (NaCl) Stress on Germination Characteristics of Gibberellic Acid (GA3) Pretreated Quinoa (Chenopodium quinoa Willd.) Seed

This research was conducted to examine the effects of gibberellic acid (GA3), which was treated to quiona (Chenopodium quinoa Willd) seeds before germination, on the germination and the seedling growth under saline conditions. Quinoa Titicaca variety, four different GA3 (0.0, 100, 200 and 300 ppm), and four different salt (0.0, 100 mM, 200 mM and 400 mM NaCl) concentrations of exposed stress. Germination power (%), germination ratio (%), germination index (%), mean germination time (day), sensitivity index (%) as of the second day of the research, and radicula length (cm), plumula length (cm), radicula fresh weight (mg), radicula dry weight (mg), plumula fresh weight (mg), and plumula dry weight (mg) on the 14th day were examined. The results indicated that the increasing doses of salt prevented germination and growth parameters of kinoa (Chenopodium quinoa Willd.) seeds. It was observed that the doses of GA3 (Gibberellic acid), which increased gradually before the doses of salt, affected germination and growth positively and significantly. The best results of germination characteristics of wheat seed were obtained from the combination of 300 ppm Gibberellic acid + 0 mM (control) salt.
