We report on the experiments on orientation of a migratory songbird, the garden warbler (Sylvia borin), during the autumn migration period on the Courish Spit, Eastern Baltics. Birds in experimental cages, deprived of visual information, showed the seasonally appropriate direction of intended flight with respect to the magnetic meridian. Weak radiofrequency (RF) magnetic field (190 nT at 1.4 MH...
بهمنظور بررسی اثر عصاره آبی اندامهای مختلف اُزمک بر جوانهزنی و رشد گیاهچهی یولاف زراعی آزمایشی بهصورت فاکتوریل در قالب طرح بلوک کامل تصادفی با سه تکرار در سالهای 1393 و 1395 در آزمایشگاه تحقیقات بذر دانشگاه محقق اردبیلی انجام شد. تیمارهای آزمایش شامل عصاره آبی اندامهای هوایی و زیرزمینی اُزمک و مخلوط آنها در نسبتی مساوی با هم و در پنج سطح غلظتی 5، 10، 20، 40 و 80 درصد حجمی بود و برای تیمار...
Lepidium sativum Linn. has been used in traditional and folklore medicine for the treatment of bronchial asthma, diabetes, local and rheumatic pain. An ethanolic extract of cress (L. sativum L.) shoot, leaf, stem and seed has been studied for antioxidative active against 1,1-diphenyl-2-picrylhydrazyl (DPPH), total glutathione S-transferase assay, reduced glutathione activity, reducing power (Fe...
BACKGROUND Maca (Lepidium meyenii) is an Andean plant of the brassica (mustard) family. Preparations from maca root have been reported to improve sexual function. The aim of this review was to assess the clinical evidence for or against the effectiveness of the maca plant as a treatment for sexual dysfunction. METHODS We searched 17 databases from their inception to April 2010 and included al...
BACKGROUND AND AIMS Karrikinolide (KAR(1)) is a smoke-derived chemical that can trigger seeds to germinate. A potential application for KAR(1) is for synchronizing the germination of weed seeds, thereby enhancing the efficiency of weed control efforts. Yet not all species germinate readily with KAR(1), and it is not known whether seemingly non-responsive species can be induced to respond. Here ...
The gas mixtures from cultures of Saccharomyces cerevisiue inhibited growth and sporulation of Aspergillus niger and germination of seeds of Lepidium sativum. In test conditions seven volatile organic metabolites in the culture gases were identified by gas-liquid chromatography (GLC) as acetaldehyde, ethyl acetate, ethanol, n-propanol, isobutanoi, and a mixture of isopentanols (I part 2-methyl-...
The seeds of Lepidium apetalum Willdenow (called "Tinglizi" in China and "Jungryukza" in Korea) have been used to discharge phlegm and improve dropsy in Oriental medicine. The present study investigated the effects of ethanol extract of the seeds of Lepidium apetalum (ELA) on atrial dynamics and atrial natriuretic peptide (ANP) secretion in beating rabbit atria. ELA increased atrial stroke volu...
Salinity is an abiotic stress that limits both yield and the expansion of agricultural crops to new areas. In the last 20 years our basic understanding of the mechanisms underlying plant tolerance and adaptation to saline environments has greatly improved owing to active development of advanced tools in molecular, genomics, and bioinformatics analyses. However, the full potential of investigati...
جنس Lepidium از خانواده Cruciferaeدر ایران 8 گونه دارد که گونه Lepidium sativum L. شاهی (ترتیزک) علاوه بر ایران در اروپای مناطق مدیترانه ای ، آسیا وآمریکا پراکنش دارد .به منظور بررسی ترکیبهای شیمیایی اسانس آن برگهای گیاه کاشته شده از منطقه شمیران در استان تهران در تابستان 1383 جمع آوری گردید وپس از خشک شدن در دمای محیط با روش تقطیر با آب اسانس گیری شد. اسانس به صورت یک لایه روغنی به رنگ ز...
