Abstract

In order to evaluate the effect of sodium nitroprusside (SNP) in reducing oxidative stress in purple coneflower (Echinacea purpurea) seedlings under saline condition, a factorial experiment with arrange of completely randomized design with four replications was conducted in research greenhouse at Sana Institute of Higher Education in 2015. In this study, the effect of the SNP as doner of Nitric oxide (NO) at 4 levels (0, 0. 1, 0. 2 and 0. 4 mM) and 3 levels of salinity stress (0, 75 and 150 mM of NaCl) were evaluated. The results showed that the interaction between SNP and salinity on fresh and dry weight of root and leaf, carotenoid and Malondialdehyde (MDA) contents, enzyme activities of superoxide dismutase (SOD), peroxidase (POD) and ascorbate peroxidase (APX) were significant. With increasing of salinity concentration, root fresh and dry weights were decreased, whereas the traits were increased by 0. 2 mM of SNP under salinity. The chlorophyll a, b and total chlorophyll contents were decreased with increasing of salinity, whereas the highest amount of carotenoid were measured in 0. 4 mM SNP under salinity conditions. The maximum level of MDA (33 nm g-1 FW) was related to 0 mM SNP and 150 mM of NaCl. The highest activities of Antioxidant enzymes SOD, POD and APX were measured in 0. 2 mM SNP and 75 mM of NaCl. The highest CAT activity (6. 50 μ M g-1 FW. Min. ) was measured in 0. 2 mM SNP that showed 90 % increasing compared with the control treatment. Total Protein content was decreased 5. 4 % under salinity stress. The highest content of Total phenol (8. 68 mg gallic acid g-1FW) was also observed in the highest level of salinity. Overall, it seemed that SNP pre-treatment increased resistance of Echinacea seedlings under salinity stress by increasing of Antioxidant enzymes activity caused.
