In order to investigate the profile of saturated and unsaturated fatty acids of camellia oil in response to salinity stress and polyamines, an experiment was conducted in March 2022 in a factorial layout based on a completely randomized design as pot culture (open air) with 12 treatments and 3 replications. The salinity stress treatment applied using Urmia Lake water at three levels (0, 15, 30 dS/m). Foliar treatment carried out in 4 levels, including 1- Foliar spraying with Spermine, 2- Foliar spraying with Spermidine, 3- Foliar spraying with Putrescine and control (no foliar spraying). The results showed that with the increase of salinity stress level, the percentage of saturated fatty acids increased but the unsaturated fatty acids of grain oil decreased. Also, the salinity stress of 30 and 15 dS/m increased the saturated fatty acids (6 and 4%, respectively) and the ratio of saturated to unsaturated fatty acids (9 and 6%, respectively), but decreased the percentage of oil (17 and 9%, respectively), monounsaturated fatty acids (4 and 2%, respectively), polyunsaturated fatty acids (3 and 1%, respectively), reduced oil yield (62 and 21%, respectively) and grain yield (52 and 10%, respectively) compared to the control. Foliar spraying with polyamines decreased the percentage of saturated fatty acids and increased the percentage of unsaturated fatty acids, unsaturated index, oil stability percentage, oil percentage, oil yield and grain yield. Therefore, foliar-applied polyamines are proven suitable to mitigate the salinity stress and improve oil composition and increase the quantity and quality of camellia grain yield.
