Abstract: (5 Views)
This research was carried out with the aim of examining the effects of different levels of salinity stress on yield, phenolic and flavonoid compounds of Galega plant as a completely randomized block design with three replications in three cultivation environments (greenhouse, open-air pot, and field) in the crop year 2023 in the research farm of the Faculty of Agriculture of Urmia University. The salinity stress was at three levels, 0.1, 5 and 10 ds/m. Salinity stress in all three culture environments caused a decrease in Galega seed yield compared to the control. On average, Galega field cultivation produced the highest seed yield (2.98 g per plant), and open air pot cultivation (2.13 g per plant) produced the lowest seed yield. Mild and severe salinity stress led to changes in the ratio of polyphenols and flavonoids. In greenhouse conditions, salinity stress of 5 and 10 ds/m increased the content of caffeic acid (44 and 62%) and chlorogenic acid (41 and 27%), respectively, compared to the conditions without salinity stress. Also, in open air pots, the salinity stress of 5 ds/m compared to the conditions without salinity stress, increased the content of caffeic acid (51%), chlorogenic acid (9%), coumaric acid (30%), acid rosmaric (53%), quercetin (86%) and cinnamic acid (17%). Under field cultivation conditions, the salinity stress was 5 and 10 ds/m, respectively, the content of chlorogenic acid (11 and 58%), coumaric acid (19 and 48%), rosmaric acid (42 and 61%), quercetin (53 and 77 percent), and cinnamic acid (18 and 42 percent). The highest content of chlorogenic acid (47.06), rutin (15), cinnamic acid (0.92) and apigenin (4.26) was obtained from the salinity stress of 10 dS/m under field conditions. These changes are probably a solution to adjust the effects of salinity stress. It is suggested that the salinity stress of 10 ds/m can be used as an inducer for the synthesis of important industrial and medicinal compounds in Galega plants. In conclusion, the data obtained showed that salinity stress significantly reduced the yield of Galega in all three culture environments, while it improved the phenolic content and antioxidant capacity of the plants.
