Abstract: (9 Views)
Mistletoe (Loranthus europaeus Jacq.) is a semi-parasitic flowering plant growing on different host trees and shrubs. In the fragile ecosystems of the Zagros forests, one of the major diseases of trees and shrubs is the L. europaeus Jacq, caused a lot of damage to these forests. The aim of this research was to investigate the different biochemical parameters in mistletoe, healthy Persian oak (Quercus brantii) and oak infected with mistletoe, and also to investigate the effect of semi-parasitic mistletoe on biochemistry components of oak leaves. The measured parameters were chlorophyll a, chlorophyll b, total chlorophyll, carotenoid, anthocyanin, proline, total protein, total phenol, DPPH radical scavenging capacity, and IC50 (Half maximal inhibitory concentration) index. The results showed that the amount of chlorophyll pigments in the leaves of mistletoe was significantly higher than that of healthy and infected oak leaves. The mean comparisons showed significant differences in the proline, total protein, anthocyanin, total phenol, DPPH radical scavenging capacity, and IC50 index content between mistletoe, healthy and infected oak individual leaves. There was a positive significant correlation between the proline and anthocyanin (R= 0.931), total phenol (R= 0.958) and DPPH radical scavenging capacity (R= 0.910). The significant positive correlation indicated that an increase in the osmolyte (proline) and antioxidant compounds such as anthocyanin and phenolic compounds, as well as the increase in the DPPH radical scavenging capacity in the leaves of oak trees under the mistletoe infection stress, are the main strategies of oak trees under the mistletoe infection stress.
