Abstract: (4348 Views)
Mistletoe (Loranthus europaeus Jacq) is an evergreen bush which is considered as a
semi-parasitic plant of Ilam forests and show off in late autumn and winter in the northern forest of Ilam. The aim of this study was to investigate the effect of mistletoe on some Quantitative characteristics and nutrient uptake in oak forests (Quercus brantii L.) of Bankol in Ilam Province. For this study, selecting the study area, then sampling was carried out with selected method on infected trees with mistletoe, that way 32 sampling plots with 1000 m2 area were selection (In the areas that there were some of infected trees with mistletoe) and relationship of infection intensity with to diameter at breast, height, canopy and trees location were studied. Also, sample of leaves were collected from healthy and infected branches of infected trees and branches of healthy trees (in equal condition of morphologic, diameter at breast, height and canopy of trees). Then concentration at N, P, K, and Zn at foliage were measured. Results show that most of infected trees were in middle diameter and canopy classes and also in high trees. The results of the assessment of disease severity with BVR method show that most of the contamination were in the upper crown. In terms of potassium element, infected branches contain more potassium. Nitrogen decreased in infected branches compared to healthy ones. Other elements didn’t show a significant difference.
