allelopathy is one of the main factors limiting the plants growth. the present study investigated the effect of aqueous extract of leaves and fruit of artemisia sieberi that is an important species for rangeland rehabilitation on seed germination and seedling growth of three alfalfa species (medicago sativa cv. nikshahri, medicago polymorpha and medicago scutellata cv. robinson) in laboratory a...
Allelopathy is described as the positive or negative effect that one plant causes on growing of another, which occurs through reléase chemical components to environment. The 'tarwi', Lupinus mutabilis Sweet., a native legume from Andean region whose seeds have high protein content, however, these bitter taste due presence alkaloids, metabolites been reported allelochemical components, uses in ...
Ensifer medicae WSM1369 is an aerobic, motile, Gram-negative, non-spore-forming rod that can exist as a soil saprophyte or as a legume microsymbiont of Medicago. WSM1369 was isolated in 1993 from a nodule recovered from the roots of Medicago sphaerocarpos growing at San Pietro di Rudas, near Aggius in Sardinia (Italy). WSM1369 is an effective microsymbiont of the annual forage legumes M. polymo...
to study the effect of planting dates and genistein application on nitrogen content and nodulation of three annual medic species (medicago polymorpha cv. santiago m. rigidula cv. ragidula, and m. radiata cv. radiata), an experiment was conducted during 2005-2006 in the research farm of faculty of agriculture, shahed university, tehran. the treatments were arranged as split split plot in a rando...
Six Medicago species were investigated to characterize and valorize plant genetic resources of pastoral interest in Morocco. Samples were obtained from the core collection of the South Australian Research and Development Institute (SARDI). The transferability of single sequence repeat markers of Medicago truncatula was successful with 97.6% efficiency across the five species. A total of 283 all...
We studied the genetic structure of 176 bacterial isolates from nodules of Medicago sativa, M. lupulina and M. polymorpha in fifteen sites distributed in three localities in Mexico. The strains were characterized by multilocus enzyme electrophoresis, plasmid profiles, PCR restriction fragment length polymorphism of 16S rRNA genes and of the intergenic spacer between 16S and 23S rRNA genes, and ...
جهت انتخاب یونجههای 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...
Medicago polymorpha L. is a herbaceous legume that can be useful pasture crop, especially in Mediterranean climates. This study aimed to analyze the genetic variation five populations of M. collected from different eco- geographic regions Tunisia using eight SSR markers. The transferability 112 markers distributed on chromosomes truncatula Gaertn. showed 50 could amplified polymorpha. Among the...
Both ecological and evolutionary processes can influence community assembly and stability, and native community members may respond both ecologically and evolutionarily as additional species enter established communities. Biological invasions provide a unique opportunity to examine these responses of native community members to novel species additions. Here, I use reciprocal transplant experime...
