Pollen-Mediated Movement of Herbicide Resistance Genes in Lolium rigidum
The transfer of herbicide resistance genes by pollen is a major concern in cross-pollinated species such as annual ryegrass (Lolium rigidum). A two-year study was conducted in the greenhouse, under favorable conditions for pollination, to generate information on potential maximum cross-pollination. This maximum cross-pollination rate was 56.1%. A three-year field trial was also conducted to stu...
متن کاملمطالعه آت‌اکولوژی گونه Lolium rigidum Gaud. در استان مازندران
مطالعات آت‌اکولوژی (aut-ecologi)، اطلاعاتی بنیادی برای مدیریت اکوسیستم‌های مرتعی به وجود می‌آورد. در این تحقیق، آت‌اکولوژی Lolium rigidum با نام فارسی چچم بررسی شده است. ابتدا پراکنش جغرافیایی، فنولوژی، گونه‌های گیاهی همراه، ضریب خشکی، ویژگی‌های فیزیکوشیمیایی خاک، بررسی‌های اقلیمی و سایر عوامل مؤثر بر پراکنش این گونه، از جمله تغییرات ارتفاعی در 9 رویشگاه انتخابی از استان مازندران بررسی شد. سپس ...
متن کاملFoliar zinc biofortification effects in Lolium rigidum and Trifolium subterraneum grown in cadmium-contaminated soil
Zinc (Zn) is an important micronutrient that can alleviate cadmium (Cd) toxicity to plants and limit Cd entry into the food chain. However, little is known about the Zn-Cd interactions in pasture plants. We characterized the effects of foliar Zn application and Cd uptake by ryegrass (Lolium rigidum L.) and clover (Trifolium subterraneum L.) grown on Cd-contaminated soils; all combinations of fo...
متن کاملLolium rigidum, a pool of resistance mechanisms to ACCase inhibitor herbicides.
Three diclofop-methyl (DM) resistant biotypes of Lolium rigidum (R1, R2, and R3) were found in different winter wheat fields in Spain, continuously treated with DM, DM + chlortoluron, or DM + isoproturon. Herbicide rates that inhibited shoot growth by 50% (ED50) were determined for DM. There were found that the different biotypes exhibited different ranges of resistance to this herbicide; the r...
متن کاملMultiple herbicide-resistant Lolium rigidum (annual ryegrass) now dominates across the Western Australian grain belt
Lolium rigidum (annual or rigid ryegrass) is a widespread annual weed in cropping systems of southern Australia, and herbicide resistance in L. rigidum is a common problem in this region. In 2010, a random survey was conducted across the grain belt of Western Australia to determine the frequency of herbicide-resistant L. rigidum populations and to compare this with the results of previous surve...
