Abstract: (46 Views)
Camelina (Camelina sativa) is a flowering plant from the Brassicaceae family. This cold-resistant plant has high nutritional value and is a multipurpose plant. Salinity stress is a growing problem in the agricultural lands of Iran and the world, which reduces the growth and development of plants. How this plant reacts to salinity stress and how to improve its resistance have been considered in this category. Various improvers have been recommended to increase resistance to stress. In this research, chitosan and iron, together with salt, have been applied to Camelina. Chitosan is one of the compounds that stimulates the plant's immune system to protect against stress factors, and the iron element plays an important role in the structure of cytochromes, photosynthesis and respiration by fixing N2. In order to implement this research, this experiment was carried out based on a randomized block design with three replications at Kharazmy Universityin 1402. In the present research, we investigated the salinity levels of 0, 8, 12 ds/m, equivalent to 0, 5.12, and 7.6 g/L of NaCl, and chitosan treatment with concentrations of 0, 0.2, and 0.4 g/L, and iron was also investigated with concentrations of 0, 3, and 6 g/l and the interaction of their different concentrations to improve growth. Following salt stress, different enzymatic antioxidants showed different reactions. The activity of the ascorbate peroxidase enzyme increased after the increase in salinity stress, and compared to the control, the activity of the peroxidase enzyme increased in the beginning compared to the control and did not record many changes, and the activity of the enzyme phenylalanine ammonia-lyase (PAL) increased with increased salinity stress compared to the control. In the combined study of the effect of chitosan elicitor and iron element on salinity stress, it was observed that chitosan elicitor improved the stress conditions by increasing the activity of peroxidase enzyme, photosnthase pigments, shoot fresh weight, and decreasing MDA and H2O2, the activity of ascorbate peroxidase enzyme and anthocyanin did not change much and this indicates that the effect of elicitor and iron element on salinity stress has improved.
