Abstract :

In order to investigate the effect of foliar application of silica fertilizers on malondialdehyde and antioxidant enzymes amounts in marigold (Calendula officinalis L.) under salt stress conditions, a factorial experiment was conducted in a completely randomized design in 2017 with four salinity levels (0, 30, 60, and 90 mM NaCl) and three silicon levels (0, 0.3, and 0.6 mL/L silamol) from silamole source with three replications in the greenhouse of Eleventh District of Tehran Municipality. The results of the study showed that the level of malondialdehyde was not significantly different from the control up to a salinity level of 30 mM, but a significant increase was achieved with increasing salinity to 60 mM. The effect of silamol consumption was also significant on antioxidant enzymes peroxidase, catalase, superoxide dismutase and malondialdehyde. The interaction effects of salinity and silamol were significant only on malondialdehyde content. Based on the research findings, it can be stated that in salinity conditions, planting Marigold can be recommended by using silamol.
