Abstract

 This research has been performed in order to description of the symptoms and the evaluation of the co-occurrence in different severity of charcoal oak diseases ofQ. castaneifolia in the Qoroq forest park. signs and symptoms of CHARCOAL DISEASEs include number, height, area and depth of canker in 385 tree with an average diameter of 52/5 cm and a diameter range of 15 to 140 cm at seven transects were recorded over a period of six months. Based on the damage severity of disease, trees in the five classes: Healthy and no evidence of disease (1), bleeding only in the very small surface (2), bleeding, developed canker plus beetles (3), bleeding and decay of tissue developed and deep cankers with beetle activity (4), and dead trees (5), Grouped. The analysis of variance demonstrated that mean of height, depth and area of canker in the trees disease was different and also a significant correlation was detected between depth and area of canker with severity of CHARCOAL DISEASE. Results of evaluation of the co-occurrence severities of different disease using paired quadrat covariance showed that trees and dead trees are positively correlated, such that the difference in disease severity between the trees was greater, the co-occurrence was less likely. These results, the pattern of the distribution and development of CHARCOAL DISEASE offers that in the management and reforestation infected forests is applications.
