نارون ملج (Ulmus glabra) گونه ای جنگلی است که از لحاظ اقتصادی ارزش بالائی دارد اما به دلیل حساسیت به بیماری مرگ هلندی نارون در معرض نابودی قرار گرفته است. به همین دلیل تکثیر درون شیشه این گیاه جهت اصلاح ژنتیکی آن حائز اهمیت است. در این تحقیق برای اولین بار جنین های سوماتیک کروی شکل بطور مستقیم از جداکشت برگ گیاهان درون شیشه ای به دست آمد. در آزمایش اول ریزنمونه های دو ژنوتیپ مختلف بر روی محیط M...
Bacterial endophytes, non-pathogenic bacteria residing within plants, contribute to the growth and development of plants and their ability to adapt to adverse conditions. In order to fully exploit the capabilities of these bacteria, it is necessary to understand the extent to which endophytic communities vary between species and over time. The endophytes of Acer negundo, Ulmus pumila, and Ulmus...
s: It had been demonstrated that Glycyrrhiza glabra extract has biological beneficial impacts include anti-inflammatory as well as anti-allergic properties, although there is little published data about its probable side effects on the placental integrity. Since, there is not enough data regarding the impacts of G. glabra on the placental histo-morphology. Therefore, this study was carried out ...
Atherosclerosis which results from gradual deposition of lipids in medium and large arteries is a leading cause of mortality worldwide. Glycyrrhiza glabra is an herb of Fabacea family which contain hypolipidemic compounds and flavonoids with high antioxidative properties. This study was conducted to determine the effect of Glycyrrhiza glabra extract on blood lipids and atherosclerosis in rabbit...
Natural infection of Lymnaea glabra and Lymnaea truncatula by Fasciola hepatica and/or Paramphistomum daubneyi was studied at two periods of risk (June-July and September-October) in 11 French farms known for their high prevalences of F. hepatica infection in ruminants. A total of 1,778 L. truncatula and 2,396 L. glabra measuring 6 mm or more in height were collected to determine the prevalence...
BACKGROUND Studies have shown that the barks and roots of some Apocynaceae species have anticancer and antimalarial properties. In this study, leaf extracts of five selected species of Apocynaceae used in traditional medicine (Alstonia angustiloba, Calotropis gigantea, Dyera costulata, Kopsia fruticosa and Vallaris glabra) were assessed for antiproliferative (APF) and antiplasmodial (APM) activ...
سوسک برگخوار نارون، از آفات مهم درختان نارون ulmus glabra l.) , (ulmus densa l. محسوب می شود و همه ساله خسارت قابل توجهی به آنها وارد می سازد. در تحقیقی که در سال 1377 در شهر قزوین صورت گرفت، بیواکولوژی این حشره مورد بررسی قرار گرفت. برای این منظور، از هر دو گونه نارون، 20 درخت از 10 ناحیه مختلف شهر بطور تصادفی انتخاب گردید. در نمونه برداری هفتگی، از هر درخت 40 نمونه (10 نمونه از هر یک از 4 جهت...
Glycyrrhiza glabra L. (family-Fabaceae-Leguminosae) is one of the important medicinal plant, commonly called as ‘liquorice’. The main ingredient of liquorice is ‘glycyrrhizin’. The present experiment was focused on the anti-inflammatory activity of hydro alcoholic extract of G. glabra (HAEGG) root against carrageenan induced rat paw oedema at dose levels of 100, 200, and 300 mg/kg orally. The H...
Seed dispersal of Guarea glabra and G. kunthiana (Meliaceae) in Monteverde, Costa Rica was studied to determine how seed predation and secondary dispersal affect the distribution of seeds available for recruitment. The arillate seeds are consumed mainly by birds that regurgitate or defecate the seeds intact. After dispersal, 45.6% of G. glabra and 26.6% of G. kunthiana seeds were buried 1– 3 cm...
