Ecology of wood‐inhabiting fungi in northern forests of Iran

Forest Pathology (2019)

Ehsan Bari Hamed Aghajani Katie M. Ohno Roya Shahi Mike Hale

Abstract Wood‐decay fungi are important in forest ecosystems and play an important role in nutrient and carbon recycling. The scope of this research was to identify wood‐inhabiting and wood‐decay macrofungi and determine their ecology. We sampled standing trees and dead wood of oak and hornbeam in the northern forests of Iran, specifically in Mazandaran and Golestan provinces. We assessed the influence of field slope, elevation, site direction and the height of fungal sporocarp position on the tree. The species of wood‐inhabiting and wood‐decay fungi belonged to 11 families: Polyporaceae; Stereaceae; Ganodermataceae; Physalacriaceae; Agaricaceae; Xylariaceae; Pluteaceae; Coprinaceae; Strophariaceae; Pleurotaceae; and Hydnaceae. The most common fungal species identified belonged to the Polyporaceae and Ganodermataceae and predominantly grew on trees growing on a slope of 20%, at an altitude of 700–900 m, 0–3 m from the ground a southwesterly site direction and the northern sides of both tree species. These results indicated that field slope was the most important factor in determining fungal sporocarp abundance.

Soil properties across a chronosequence of Ailanthus altissima in semiarid plantations

Sustainable Forestry (2019)

Hamed Aghajani

Afforestation is a main tool for preventing desertification and soil erosion in arid and semiarid regions of Iran. Large-scale afforestation, however, has poorly understood consequences for the future ecosystems in the term of ecosystems protection. The objective of the present study is to identify changes in soil properties following different intervals of planting of Ailanthus altissima (tree of heaven) in semiarid afforestation of Iran (Chitgar Forest Park, Tehran). For this purpose, sand, silt and clay ratios, bulk density, soil moisture, pH, electrical conductivity, phosphorus, potassium, magnesium, calcium, sodium, total soil N, and total carbon was measured. Our study highlighted the potential of the invasive trees by A. altissima, to alter soil properties along chronosequence. Almost all soil quality attributes showed a declining trend with stand age. A continuous decline in soil quality indicated that the present land management may not be sustainable. Therefore, an improved management practice is imperative to sustain soil quality and maintain long-term productivity of plantation forests. Thinning activity will be required to reduce the number of trees competing for the same nutrients especially in a older stand to protect forest soils.

HEARTWOOD AND SAPWOOD FEATURES OF SORBUS TORMINALIS GROWN IN IRANIAN FORESTS

Wood Research (2020)

Mohsen Bahmani Leila Fathi Gerald Koch Farhad Kool Hamed Aghajani

In the present study anatomical, histometrical, chemical and physical properties of the wood of 45-year old trees were determined.For this purpose, three trees were randomly cut at Sangdeh-Mazndaran located in the northern part of Iran.Disks and logs were removed at breast height to study the respective wood properties.Fiber length, fiber diameter, fiber lumen diameter, cell wall thickness as well as lignin and cellulose content of sapwood are superior to those of heartwood.Growth rings boundaries are fairly distinct and can be distinguished by only two to three compact fiber layers.The wood is diffuse-porous and vessels are small and predominately solitary, hardly visible to the naked eye on transverse sections.Most rays are 2-seriate interspersed with only few 3-seriate and uniseriate rays, and composed of procumbent body cells with occasional marginal rows of upright and/or square cells.

Improving the biological properties of Fomes fomentarius MG835861 exopolysaccharide by bioincorporating selenium into its structure

Carbohydrate Polymer Technologies and Applications (2021)

Hale Alvandi Ashrafalsadat Hatamian-Zarmi Bahman Ebrahimi Hosseinzadeh Zahra Beagom Mokhtari‐Hosseini Ewald Langer

Selenium (Se) is one of the essential elements for human health, where Se-containing compounds can prevent cancer and reduce mortality by regulating of the cell cycle and apoptosis. Exopolysaccharides from Fomes fomentarius have been used in traditional medicine to treat cancer. It appears that the combination of Se and fungal polysaccharides may be more effective. The effect of adding Na2SeO3 to the culture medium of the Iranian medicinal fungus F. fomentarius is investigated in this study. Adding 20 mg/L Na2SeO3 to the culture medium changed the F. fomentarius morphology and improved the structure of exopolysaccharides. Several methods, including FTIR, EDS, and ICP-OES, confirmed the presence of Se in the exopolysaccharides of F. fomentarius. The results demonstrated that the addition of Na2SeO3 increased the antibacterial activity against S.aureus (60%) and antioxidant activity (17.4%) significantly (p < 0.05). The cytotoxicity of these exopolysaccharides against 5637, A549, and KYSE30 cancer cells was also significantly increased (p < 0.05), and the viability of EPS-Se treated 5637 cells reached less than 10% after 72 h. Finally, F. fomentarius Se-polysaccharides can be used as a dietary supplement.

Evaluation of Pinus eldarica hazardous criterias in the Babol city (Mazandaran province, northern state of Iran)

International Journal of Advanced Biological and Biomedical Research (2013)

Maziar Haidari Hamid Jalilvand Hamed Aghajani Mehran Nasiri

Any defects in street trees may cause injuries to human, vehicles and buildings. This research was investigated in the Babol city, Mazandaran province, in the northern state of Iran.Used the perfect inventory methods and measured the diameter at breathe height (DBH), height and hazardous criteria (dead woods, cracks or seams, decay, wound or cankers, root problems, weak branch unions and skew from vertical line). In each hazardous criterion classes compered the Slenderness (h/d); height (m) and diameter at breathe height (cm). The means of different between Slenderness (h/d), height (m) and diameter at breathe height (cm) in the hazardous criteria classes were estimated by ANOVA test. Data analyzing was done by SPSS16 software. Results showed that the mean of DBH and h/d in the hazardous class (class one) was higher the other classes in the seven hazard criteria, but mean height of tree in the class 3 (non-hazard classes) was higher quantity. Results showed that the different between three classes of hazard in the seven hazard criteria was significant. Overall results showed that the hazardous class (class one) has a higher h/d quantity and more hazardous potential.

Biological Resistance of Elm (Ulmus carpinifolia var. Umbelifera) Trees against Fungal Endophytes and White Rot Decay Fungi

Sustainable Forestry (2020)

Huijun Dong Mina Raiesi Mohsen Bahmani Ali Jafari Hamed Aghajani

Urban trees are one of the valuable storage in metropolitan areas. Nowadays, a particular attention is paid to the trees and spends million dollars per year to their maintenance. Trees are often subjected to abiotic factors, such as fungi, bacteria, and insects, which lead to decline mechanical strength and wood properties. The objective of this study was to determine the potential degradation of Elm tree wood by Phellinus pomaceus fungi, and Biscogniauxia mediteranae endophyte. Biological decay tests were done according to EN 113 standard and impact bending test in accordance with ASTM-D256-04 standard. The results indicated that with longer incubation time, weight loss increased for both sapwood and heartwood. Fungal deterioration leads to changes in the impact bending. In order to manage street trees, knowing tree characteristics is very important and should be regularly monitored and evaluated in order to identify defects in the trees.
