Abstract: (246 Views) |
St. John's wort (Hypericum perforatum L.) has effective compounds such as hypericin and hyperforin. Nanoparticles and elicitors increase secondary metabolite production and improve the physiological indicators of plants. Therefore, the purpose of this research is to investigate the effect of iron nanoparticle (no iron nanoparticle application and application of 50 and 100 µM) and salicylic acid (no application of salicylic acid and application of 40, 80 and 120 µM) on some morphophysiological indices (percent regeneration percentage, fresh weight, plant height, root length, root number, number of leaves, leaf area, content of photosynthetic pigments) and phytochemical (total phenolic and flavonoid content) of Hypericum perforatum L. The results indicated that the interaction effect of iron nanoparticles and salicylic acid on regeneration percentage, fresh weight, number of leaves, leaf area, root length, total chlorophyll content, phenol, and flavonoid content was significant at the probability level of 1%. In contrast, plant height and number of roots were insignificant. The comparison of the averages revealed that the highest percentage of regeneration and fresh weight was observed in the control treatment and the treatment combination of 50 µM iron nanoparticles and 120 µM salicylic acid, respectively. In general, the simultaneous application of iron nanoparticles (50 µM) and salicylic acid (40 and 80 µM) significantly positively affected the morphophysiological and phytochemical characteristics of Hypericum perforatum L. |
