Around the world, species from the genus Tilia are commonly used because of their peripheral and central medicinal effects; they are prepared as teas and used as tranquilizing, anticonvulsant, and analgesic agents. In this study, we provide evidence of the protective effects of organic and aqueous extracts (100 mg/kg, i.p.) obtained from the leaves of Tilia americana var. mexicana on CCl4-induc...
Variations in fruits morphology of Tilia spp. were studied along longitudinal and altitudinal range. Ten populations of Tilia spp.from Golestan, Mazandaran and Gilan Provinces (N. Iran) were selected. After biometrical measurements and Scanning Electron Microscopic (SEM), Cluster Analysis divided the population into seven groups. Discriminat Analysis showed that among all traits studied, size o...
در این مطالعه، تعداد زیادی نمونه درختی از رویشگاه‌های مختلف و نمونه‌های هرباریومی مورد مطالعه قرار گرفت. مشکلات تاکسونومیک فراوانی در رابطه با شناسایی گونه‌های جنس نمدار در ایران وجود دارد، نتایج مطالعات تعدادی از گیاه‌شناسان بر روی این جنس، تنها نمایانگر حضور گونه Tilia platyphyllos و در مطالعات برخی گونه Tilia dasystyla و در تعدادی هم گونه Tilia rubra در ایران است. در واقع نتایج مطالعات اکث...
UNLABELLED PREMISE OF THE STUDY Microsatellite markers in the genus Tilia were developed to investigate the genetic variation in T. platyphyllos and its relationship with T. cordata. • METHODS AND RESULTS Fifteen microsatellite markers were developed using a microsatellite enrichment protocol. Most loci show a high level of polymorphism in two T. platyphyllos populations from France. The n...
این تحقیق به منظور شناسایی گونه های مختلف جنس نمدار با استفاده از نشانگرهای ریخت شناسی، آناتومی و مولکولی انجام پذیرفت. به این منظور، ابتدا 13 رویشگاه نمدار در شمال ایران شناسایی و در هر رویشگاه، تا 15 پایه، با فواصل حداقل 100 متر از یکدیگر انتخاب شدند. از هر درخت نمونه های برگ، گل و میوه جمع آوری شد. در یافته های این تحقیق، هفت گروه متمایز ریختی میوه برای جنس نمدار در شمال ایران شناسایی شد. سط...
In vitro propagation of Tilia platyphyllos Scop. has been achieved by axillary shoot proliferation and somatic embryogenesis. The influence of tree age, explant source, genotype, and phytohormones on micropropagation of juvenile and mature trees of Tilia platyphyllos has been investigated. Nodal segments and shoot tips were used as initial explants for axillary shoot proliferation. Low concentr...
The present research was conducted to find the influence of some topographic factors on distribution of large-leaved lime (Tilia platyphyllos Scop.) and its natural regeneration characteristics in "Vaz" forest (northern Iran). After identification of site and preparation of topography map, selective sampling method was carried out for tree inventory in plots. The sample plots were circular in 1...
Many species of plants produce leaves with distinct teeth around their margins. The presence and nature of these teeth can often help botanists to identify species. Moreover, it has long been known that more species native to colder regions have teeth than species native to warmer regions. It has therefore been suggested that fossilized remains of leaves can be used as a proxy for ancient clima...
