جهت انتخاب یونجه های یکساله پرمحصول برای کشت پاییزه در منطقه دشت گرگان سه گونه یونجه یکساله خارجی شامل mdicago scutellata ، medicago truncatula، medicago littoralis و دوگونه یونجه بومی medicago orbicularis و medicago polymorpha در قالب طرح آماری بلوکهای کامل تصادفی با چهار تکرار برای مدت سه سال در ایستگاه عراقی محله گرگان مورد بررسی قرار گرفتند. نتایج حاصل نشان داد که بسته به نوسان عوامل اقلیم...
یونجه یک ساله یکی از مهم ترین گیاهان علوفه ای جهان به شمار می رود. به منظور بررسی اثر غلظت های مختلف شوری بر جوانه زنی و رشد گونه های medicago scutellata، medicago polymorpha، medicag truncatula و medicago rigidula، آزمایشاتی به صورت فاکتوریل در قالب کاملاً تصادفی در چهار تکرار با شش سطح شوری (صفر، 5، 10، 15، 20 و 25 دسی زیمنس بر متر) انجام شد. ویژگی های سرعت جوانه زنی، درصد جوانه زنی، طول ساقه...
Ensifer meliloti strain RRI128 is an aerobic, motile, Gram-negative, non-spore-forming rod. RRI128 was isolated from a nodule recovered from the roots of barrel medic (Medicago truncatula) grown in the greenhouse and inoculated with soil collected from Victoria, Australia. The strain is used in commercial inoculants in Australia. RRI128 nodulates and forms an effective symbiosis with a diverse ...
ABSTRACT- Annual Medicago species (Medicago spp.) are native to the Mediterranean region and widely used in fields and pastures in Iran. There are several methods of sowing annual Medicago species, each with different effects on the performance. However, there is currently no sufficient information about the appropriate methods for sowing Medicago species. In order to evaluate methods of sowing...
Wild populations of Medicago ciliaris and Medicago polymorpha were subjected to four salt treatments 0, 50, 100 and 150 mM NaCl, plant growth and proline concentration in leaves were assessed. The analyzed data revealed significant variability in salt response within and between the two species, depending on the salinity level. It was found that high NaCl concentrations affected all the growth ...

Ensifer medicae WSM244 is an aerobic, motile, Gram-negative, non-spore-forming rod that can exist as a soil saprophyte or as a legume microsymbiont of Medicago species. WSM244 was isolated in 1979 from a nodule recovered from the roots of the annual Medicago polymorpha L. growing in alkaline soil (pH 8.0) in Tel Afer, Iraq. WSM244 is the only acid-sensitive E. medicae strain that has been seque...
The nutritive value of the annual alfalfa (Medicago rigidulla, Medicago polymorpha and Medicago scutellata) species harvested at flowering stage was assessed by chemical composition, in vitro dry matter and nitrogen digestibility, in sacco dry matter and nitrogen degradation (0, 8, 12, 24, 48 and 72 h) and palatability (short-term intake rate, STIR) methods. Mean values of the chemical analysis...
به منظور بررسی تأثیر غلظت های جنستئین بر میزان نیتروژن و گره زایی گونه های یونجه یک ساله، در دمای ˚c5 منطقه ریشه، آزمایشی در شرایط کنترل شده در اتاقک رشد با دمای ˚c25/20 روز/ شب بالای سطح خاک انجام گرفت. سه گونه یونجه یک ساله شامل medicago polymorpha ، medicago radiata و rigidula medicago که با مناطق سرد و معتدله سازگاری دارند و پنج سطح جنستئین شامل0، 10، 20، 30 و40 میکرومول بر لیتر در نظر گرفت...
