Introduction: With thirteen critical erosion hubs containing an area of roughly 532 thousand hectares, and 14 regions influenced by wind erosion with an area of 1144311 hectares, the Yazd province ranks fifth among the Iranian provinces in terms of the magnitude of crisis hub, and third in terms of the extent of affected areas. The history of desertification activities in the province dates bac...
Drought and grazing rangelands play an important role in changing the structure of vegetation and losing the biodiversity of natural ecosystems. In this research, in order to determine the effects of drought and livestock grazing on the vegetation structure of rangelands located in the Nakhab Forest of South Khorasan Province, species abundance, biodiversity, and range condition and trend were ...
A modern classification of pastures in Karakalpak Ustyurt has been developed, which combines 7 pasture types (Anabasis salsa, Salsola arbusculiformis-Anabasis Artemisia terrae-albae-Anabasis Haloxylon ammodendron, Tamarix hispida-T. elongata, Kalidium caspicum, Halocnemum strobilaceum), 2 classes (pastures stratal plains on gray-brown soils and drainless depressions solonchaks) 42 varieties, a ...
Background and Objectives: The effect of endurance training on lipid profile and cardiovascular endurance in normal rat after Bunium Persicum Extract (BPE) administration has been previously investigated. In the present study, the effect of co-administration of endurance training and persicum extract on plasma lipid and lipoproteins in hypercholesterolemic male mice was examined. Materi...
Podophyllotoxins represent an important and unique position among natural products. They serve as the starting material for the semi-synthetic anticancer drugs etopside and teniposide, so considerable attention has focused on the availability of these aryltetralin lignans. Linum is one of the genera, with some reports on the presence of podophyllotoxin and related compounds, such as L. album, L...
the genetic diversity of 20 iranian populations of bunium persicum has been evaluated with random amplified polymorphic dna (rapd) and amplified fragment length polymorphism (aflp) markers. fresh leaves of seedlings from each population were used for genomic dna extraction. analysis of banding patterns of 15 rapd primers and 17 aflp primer combinations, revealed 192 (86%) and 228 (75%) polymorp...
Introduction: Trachyspermum copticum, Bunium persicum and Cuminum cyminum involve the most important medicinal plants in Apiaceae family in Iran which can be observed in different natural habitats of Yazd province. Therefore, these three native medicinal plants of Yazd province were assessed in regard with the components and antioxidant properties of their seed essences. Methods: In this exper...
This study aimed to estimate of spatial distribution scope of plant species and preparation of predictive distribution maps of plant species using Artificial Neural Network (ANN) in Taftan west rangelands of Khash city. To this end, vegetation sampling was carried out by random-systematic method after identification and separation of plant species habitats. In order to sample the soil at each h...
یکی از گونههای چوبی کمتر شناخته شده بومی منطقه زیر کوه قائن در شرق ایران، ammodendron persicum با نام محلی دیودال می باشد. در این تحقیق از سه پایه منتخب برای مطالعات ویژگیهای چوب آن استفاده گردید. برای اولین بار چوب این گونه کویری از جنبههای مختلف فیزیکی و آناتومیکی مورد مطالعه قرار گرفته است. نتایج بررسیها نشان داد چوب گونه دیودال جزء پهن برگان بخش روزنهای میباشد که سرتاسر مقطع عرضی آن د...
