This study was conducted in oak forests of Ilam province in order to evaluate the morphological characteristics of old trees including diameter at breast height, trunk height, whole tree height, minimum and maximum crown diameter, crown health, crown vitality, crown symmetry, health and form of the trunk, Was investigated. Selection of old trees was performed based on the criteria of DBH and wi...
The present study models the effect of climate change on distribution Persian oak (Quercus brantii Lindl.) in Zagros forests, located west Iran. modeling is conducted under current and future climatic conditions by fitting machine learning method Bayesian additive regression tree (BART). For anticipation potential habitats for oak, two general circulation (GCMs) CCSM4 HADGEM2-ES representative ...
In many arid and semi-arid regions, increasing water scarcity pushes woody species to their physiological limits, making strong drought resistance essential for adaptive forest management. Here, we examined morpho-physiological biochemical responses of the forestry-relevant Persian oak (Quercus brantii Lindl.) black poplar (Populus nigra L.). a 120-day greenhouse pot experiment, seedlings were ...
This study was accomplished with the aim of investigating the effects of tree decline and slope aspect on leaf morphological traits and determining the indicator morphological traits that indicate the leaf diversity of Persian oak trees in relation to habitat conditions and environmental stresses in Mellah Siah forests of Ilam. Two forest habitats were selected on the northern and southern slop...
Yellow mistletoe is a semi-parasite plant lives in the Zagros forests on Persian oak trees. Mechanical control is one of the basic acts to manage yellow mistletoe contamination. This research aimed to evaluate the performance of mechanical methods; wood-glue, clay, black plastic, natural color and control treatment to control yellow mistletoe at different altitudes and selecting the most sui...
The antibacterial effect of the previously reported Bi2WO6/Ag3PO4/Ag Z-scheme heterojunction photocatalyst compared with a phytobiotics named, aqueous extract Persian Oak fruit. impact both materials on expression urease gene was checked in two kinds samples such as clinical and standard Helicobacter pylori (H. pylori). differences were collected by real-time PCR from strains H. well MIC MBC fo...
Once, Europe was one large natural area, across which species of animals and plants were able freely to move and disperse. Today, a satellite image of Europe looks like a Persian carpet cut into millions of small rectangular pieces, each fashioned by the plough and the spade over thousands of years of cultivation. The consequence of this change is that species have disappeared. For example, ani...
