Madicago sativa Linn, commonly known as 'Alfalfa', is a tonic plant rich in proteins, minerals, enzymes and vitamins, Bulk quantity of the whole plant is required in the pharmaceutical industries especially in homoecopathic pharmacies, Hence, there is a great need to cultivate this plant for sustained supply of the drug. Use of good and adequate phosphatecontaining farm yard manure, timely irri...
A potential strategy to decrease the levels of self-seed production during the seed increase stages of alfalfa (Medicago sativa L.) synthetic cultivar development is selection for decreased self-fertility. The underlying genetics of this trait have not been elucidated and, therefore, a study was designed to identify genetic determinants of alfalfa self-fertility. An F1 mapping population develo...
In this research the effect of ethinyl estradiol on somatic embryogenesis of Medicago sativa was investigated. Seeds were grown in vitro on MS medium containing 2,4-D, Kin and NAA for callus induction. Plant regeneration media with 14 different combinations of auxin, cytokinin and ethinyl estradiol were provided. Three to four-week old celli and stem or hypocotyl segments of Medicago sativa wer...
Exogenous nitrogen (N) inputs greatly change the emission and uptake of carbon dioxide (CO2) methane (CH4) from temperate grassland soils, thereby affecting (C) budget regional terrestrial ecosystems. Relevant research focused on natural grassland, but effects N fertilization C exchange fluxes different forage soils driving mechanisms were poorly understood. Here, a three-year addition experime...
به منظور ارزیابی تأثیر زئولیت در رشد گیاهان در شرایط کم آبی، در این تحقیق پس از آماده سازی خاک گونههای Cymbopogon olivieri ،Medicago sativa، Medicago scutellata در سه سطح زئولیت (2 گرم و 4 گرم و صفر در کیلوگرم خاک گلدان) با 15 تکرار در نظر گرفته شد. پس از اطمینان از جوانهزنی بذرها، تنش 7 روزۀ آبیاری بر روی آنها اعمال گردید. نتایج نشان داد که با اعمال تنش اول تأثیر کاربرد زئولیت در بهبود زند...
We investigated the functional significance of extraradical mycorrhizal networks produced by geographically different isolates of the arbuscular mycorrhizal fungal (AMF) species Glomus mosseae and Glomus intraradices. A two-dimensional experimental system was used to visualize and quantify intact extraradical mycelium (ERM) spreading from Medicago sativa roots. Growth, phosphorus (P) and nitrog...
Awareness of the forage nutritive value of rangeland species is important to provide a balanced diet in order to meet the nutritional requirements of ruminants and to determine the suitable grazing time and rangeland grazing capacity. Hence, different laboratory methods were used to compare the nutritional value of Centaurea cyanus, Fumaria officinalis, Galium tricornutum and Vicia sativa as co...
