اصلاح نباتات بر اساس مطالعه همزمان چندین صفت یکی از کارآمدترین ابزارهای به نژادگران در انتخاب ژنوتیپ های مطلوب است. به منظور گزینش همزمان عملکرد و کیفیت علوفه در festuca arundinacea ، 36 جمعیت در قالب طرح لاتیس سه گانه در سال های 1384 و 1385 در ایستگاه تحقیقات اردبیل مورد ارزیابی قرار گرفتند. صفات مورد بررسی شامل: عملکرد علوفه ، ارتفاع بوته، تاریخ ظهور خوشه، قابلیت هضم، قندهای محلول در آب، پروت...

in order to estimate the nutrient value of three dominant range species; festucaovina, trifolium montanum and alopecurus textilis via proximate analyses and gas productiontechnique, samples were collected in three stages during grazing period from 26th may to 1thseptember in six areas of sabalan mountain in north west of iran. results showed thattrifolium montanum as a legume had higher values ...

Five grass species (Dactylis glomerata L., Phleum pratense L., Lolium perenne L., Festuca arundinacea L. and the hybrid Felina (Lolium multiflorum L. × Festuca arundinacea L.)), commonly used in roughages for ruminants, were harvested at different maturities of primary growth (n = 60) and evaluated for contents of dry matter (DM), crude protein (CP), ash, crude fat, neutral detergent fibre (NDF...

The effects of topography, soil moisture, wind and grazing on the emergence and survival of seedlings of Festuca spp. were examined in the steppe zone of Patagonia, Argentina. Ungrazed and grazed field treatment plots were established on a plain and a north-facing slope at the Media Luna Ranch (43" 36' S, 71" 25' W). On the leeward and windward sides of each of 15 Festuca plants, 0.1 m x 0.4 m ...

A pot experiment was performed to study the effectiveness of remediation using different plant species and the enzyme response involved in remediating PAH-contaminated soil. The study indicated that species Echinacea purpurea, Festuca arundinacea Schred, Fire Phoenix (a combined F. arundinacea), and Medicago sativa L. possess the potential for remediation in PAH-contaminated soils. The study al...

Festuca is one of the largest genera of the grass family, which has more than 600 species with different ploidy levels. The aim of this study was to estimate the genetic diversity within 22 populations of three species of Festuca (Festuca arundinacea, F.rubra and F.ovina) using a seed storage protein electrophoresis pattern. These species showed a significant variation in the number of protein ...
