Juniperus sabina L. is a medicinal plant used in folk medicine as an abortive. Its lignanes have antineoplastic and antiviral activity, and also essential oil of Juniperus sabina L. has shown antibacterial a...
The genus Juniperus (Cupressaceae) consists of approximately GO species distributed in the orthern Hemisphere, except for J.yrocera Hocll. which extends into the Southern Hemisphere in Africa (Florin, 1963). The delimitation of the species of Juniperus is difficult in all of the world; few taxonomic studies have encompassed any large geographical or natural province. Gaussen (1968) lists 99 spe...
دارواش یک گیاه همیشه سبز، پایا و انگلی است که همه آب و عناصر ضروری خود شامل نیتروژن و یک بخش کوچک از غذای خود را از درخت میزبان و توسط یک اندام ریشه مانند به نام هوستوریوم دریافت میکند. این گیاه از نظر پزشکی و دارویی بسیار اهمیت داشته و بسیاری از اثرهای آن در درمان بیماریها به اثبات رسیدهاست. دو گونه Viscum album L. (دارواش حقیقی) و Arceuthobium oxycedri (D.C.) M. Bieb. (دارواش کاذب) هر دو از...
Plants of Juniperus communis L. var. communis, J. c. var. depressa Pursh, J. c. var. hemispherica J. & C. Presl, J. communis var. megistocarpa Fern. & St. John, J. c. var. nipponica (Maxim.) Wils., J. c. var. oblonga hort. ex Loudon and J. c. var. saxatilis Pall. were sampled and DNA fingerprinting (RAPDs, Random Amplified Polymorphic DNAs) was performed. Based on 191 RAPD bands, there was litt...

این مطالعه بهمنظور بررسی شرایط اکولوژیکی گونۀ محلب (Cerasus mahaleb)در جنگلهای شهرستان باغملکدر استان خوزستان در دو منطقه تاگک امامزاده عبداله و محبعلی انجام شد. برای این منظور از 72 قطعه نمونه به ابعاد 50×50 متر استفاده شد. با توجه به پراکندگی این گونه، روش خطی برای این مطالعه انتخاب شد. البته برای اینکه بتوانیم شرایط اکولوژیکی آن را مورد بررسی قرار دهیم، 20 خط با فاصلۀ 100 متر از یکدیگر از ر...
Using dendroisotopic techniques, we show the recovery of Juniperus virginiana L. (eastern red cedar) trees in the Central Appalachian Mountains from decades of acidic pollution. Acid deposition over much of the 20th century reduced stomatal conductance of leaves, thereby increasing intrinsic water-use efficiency of the Juniperus trees. These data indicate that the stomata of Juniperus may be mo...
Ethnobotanical surveys indicated that in the traditional medicines worldwide, several Juniperus species are utilized as antihelmintic, diuretic, stimulant, antiseptic, carminative, stomachic, antirheumatic, antifungal, and for wound healing. In the present study, essential oils obtained from heartwood samples of Juniperus virginiana L., Juniperus occidentalis Hook. and Juniperus ashei J. Buchho...
Juniperus pollen is highly allergenic and is produced in large quantities across Texas, Oklahoma, and New Mexico. The pollen negatively affects human populations adjacent to the trees, and since it can be transported hundreds of kilometers by the wind, it also affects people who are far from the source. Predicting and tracking long-distance transport of pollen is difficult and complex. One para...
