موقعیت تاکسونومیک جنس Secale L. در ایران مورد بازنگری قرار گرفت. موارد ریختشناختی و تاکسونومیک تاکسونهای متعلق به جنس مزبور بر پایه مجموعاً تعداد 50 نمونه جمعیتی و 104 نمونه هرباریومی از دامنه گسترش وسیعی از این جنس در ایران مطالعه شد. مشاهدات حاصل از این مطالعه نشان داد که جنس Secale در ایران با دو گونه: 1- Secale cereale L. subsp. ancestrale Zhuk., & subsp. cereale. 2- Secale strictum. (C....
Animals may respond to habitat quality and habitat edges and these responses may affect their distribution between habitats. We studied the movement behaviour of a ground-dwelling generalist predator, the carabid beetle Pterostichus melanarius (Illiger). We performed a mark-recapture experiment in two adjacent habitats; a large plot with oilseed radish (Raphanus sativus) and a plot with rye (Se...
استفاده از گونههای مرتعی مقاوم به خشکی و شوری در امر اصلاح و توسعه مراتع دارای اهمیت فراوانی است. چاودار کوهی یکی از گندمیان مهم مرتعی برای ایجاد چراگاه و تولید علوفه خشک است و با توجه به اهمیت این گونه مرتعی و این که تا کنــون مطالعهای در مورد تحمل به شوری و خشکی آن انجام نشده است، بنابراین در این تحقیق میزان مقاومت این گونه به تنش شوری و خشکی در مرحله جوانهزنی و اثر این تنشها بر شاخصهای ...
Local persistence of plant species in the face of climate change is largely mediated by genetic adaptation and phenotypic plasticity. In species with a wide altitudinal range, population responses to global warming are likely to differ at contrasting elevations. In controlled climate chambers, we investigated the responses of low and high elevation populations (1200 and 1800 m a.s.l.) of three ...
Conigenital obstruction of the male urethra by a diaphragm, or more frequently by valves of mucous membrane in connection with the veru-montanum, has been recorded from time to time, and in receint years an increasing amount of attention has been given to this condition. In the female any kind of congenital obstruction of the urethra appears to be extremely rare, and I have been able to find so...
The volatile constituents of the aerial parts of Carum montanum (Coss. et Dur.) Benth. et Hook. were analysed by GC-FID and GC-MS, and the main component was isolated and identified as nothoapiole. The antibacterial and antifungal activities of this compound and of the total oil were investigated against Gram-negative (P. aeruginosa, E. coli), Gram-positive (E. faecalis, S. aureus, S. epidermit...
Article history: Received on: 11/10/2013 Revised on: 07/12/2013 Accepted on: 22/12/2013 Available online: 30/12/2013 Ethanolic extracts of three medicinal plants collected from South India were analyzed for their activity towards acetylcholinestrase (AChE) enzyme. The AChE inhibition was measured spectrophotometrically. All the three species namely, Baliospermum montanum, Humboldtia brunonis Wa...
