(Received 6th Dec 2015; accepted 3rd May 2016) Abstract. Persian Oak (Quercus brantii Lindl.) is one of the most important woody species of Zagros forests in western and southwestern Iran. In order to determine the variation of morphometry and total phenolic, flavonoid and tannin contents, ripen acorns from 27 populations of Q. brantii growing wild in nine regions of western and southwestern Iran were collected and examined. The amounts of total phenolic/tannin and flavonoid contents were determined by “Folin-Ciocalteu” and “Aluminum Chloride Colorimetric” methods, respectively. Significant differences in acorn morphometry were observed between the populations and regions, and the higher values of acorn morphometry belonged to four regions of Khuzestan province. Similarly, there also were significant differences in amounts of total phenolic, flavonoid and tannin contents between different populations and regions, and the higher amount of total phenolic, flavonoid and tannin contents were observed in populations from Khuzestan province.

Australian Journal of Basic and Applied Sciences, 4(8): 3230-3237, 2010 ISSN 1991-8178 Anatomical Characters in Three Oak Species (Q. libani, Q. brantii and Q. infectoria) from Iranian Zagros Mountains A.M. Olfat and K. Pourtahmasi Department of Wood and Paper Sciences and Industries. Faculty of Natural Resources, University of Tehran. Iran Abstract: Zagros Mountains have a rich variety of tree species. So the difference in wood structure and properties allow manufacturing of wood- based products with many different appearance and uses. Since wood is a popular and useful material, it is important for us to be able to distinguish the wood of one species from another. That is the reason why we studied anatomical features of oak spp.This paper provides information on how to identify the wood due to several common features as to Quercus spp. In other words the inter specific and intra specific variability of wood anatomy among the three major oak species: Q. libani, Q. brantii and Q. infectoria of Iranian mountains (Zagros) were evaluated. Key words: Wood anatomy, Zagros Mountains, Wood structure, Inter specific & Intra specific, Variability. INTRODUCTION Scientifically rigorous accurate identifications require the wood to be sectioned and examined with a light microscope. With the light microscope even with only a 10X objective, many more features are available to use in making decision. Equally as important as the light microscope in wood identification, the reference Collection of correctly identified specimens is vital because unknown samples can be compared to it (Wheeler and Baas 1998). Overall, wood anatomy indicates that growth and development of trees are dynamic Processes.

Also they are taxonomically important for chemosystematic studies by the reason universal presence in vascular plants. In this study leaf, gall and bark flavonoids of nine populations of Quercus brantii L. varieties (Q. brantii var. belangeri and Q. brantii var. persica) are compared and reported for first time. Aqueous-ethanolic extracts of collected plant material from Lorestan Prvince aera, Iran were examined to practice flavonoid detection, isolation and identification by 2-dimensional paper chromatography (2-DPC), thin layer chromatography (TLC), UV spectroscopy and available references. Voucher specimens were prepared for reference as herbarium voucher. Results showed all of examined taxa have flavonoid sulphate, flavon C & C-/O glycosides and aglycons in their leaf, gall and bark. Apigenin, kaempferol, myricetin, naringenin, quercetin and rutin were nearly found in all of studied taxa parts. Studied samples leaf and bark had vitexin while their galls lacked.

Email: [email protected] Abstract: Tree decline resulting from climate change results in physiological weaknesses, attack by harmful pests and pathogen and threatens forest ecosystem stability. In the work described here, the effects of drought on wood density, tree ring width and variations in vessel morphology was investigated in Persian oak (Quercus brantii) in the forests of the Zagros Mountains, Ilam province, western Iran. Radial discs were cut from trunks of declined and healthy trees and wood blocks cut radially from the sapwood, heartwood and juvenile core. Observations were made on transverse sections from the blocks using microscopy. In trees with decline symptoms, wood density was greater than the healthy trees. Furthermore, declining trees had narrowest ring width, reduced vessel diameter, vessel area, and highest number of vessels and tylose in pith towards bark. It was concluded that changes in anatomical features are associated with weakening of the trees and are components in declining tree health.

Iran 2Department of Silviculture and Forest Ecology, Faculty of Natural Resources, Behbahan Khatam Alanbia University of Technology, I.R. Iran _____________________________________________________________________________________________ ABSTRACT Quercus brantii Lindl. species is known as Persian oak, West oak and Zagros oak. This species is one of the most important woody species of the Zagros forests. In this study three Persian oak populations were selected with three ranges of altitude in several regions Then, in each of these sites, 10 trees were selected . In each tree, 10 leaves were collected . The leaves of each tree were mixed and then 5 leaves were selected randomly and 20 traits were measured. Comparison of means by using Duncan’s test showed that 10 traits of 20 leaf characteristics had the lowest value in second population but there is no significant difference between first and third populations. In conclusion we can say that the second population had the highest difference of leaf morphological characteristics compared to other populations. PCA showed that the traits of leaf blade length, interval between apical and basal tooth, angle of leaf blade base, leaf blade width, interval between basal pair of tooth and blade width in 0.1 length of blade from leaf base had the greatest impact in classification.

The objective of the current study was to determine the influence of altitude and slope on physical properties and fiber dimensions of Persian oak wood. In addition, the relationship among wood properties, site conditions (temperature and rainfall) and growth traits of trees (tree height, DBH, basal area, age, crown diameter, crown basal area, volume and annual diameter increment) were studied by principal component analysis (PCA). Three altitude levels (1730, 1980 and 2250 m) and three slope classes (<30%, 30–45% and >45%) were considered in the current study. It was determined that trees growing in the intermediate altitude (1980 m) showed the highest oven-dry density values, and those in the lowest altitude (1730 m) revealed the lowest ones. The results also indicate significant statistical differences between altitude levels and slope classes on the fiber length, fiber diameter and volumetric swelling at the 99% confidence interval while no significant differences were found between average values of oven-dry density among different altitudes and slopes.
