Treatment of log yard runoff is required to avoid contamination of receiving watercourses. The research aim was to assess if infiltration of log yard runoff through planted soil systems is successful and if different plant species affect the treatment performance at a field-scale experimental site in Sweden (2005 to 2007). Contaminated runoff from the log yard of a sawmill was infiltrated throu...
Isoproturon resistant biotype of P. minor germinates early, shows higher germination percentage and faster rate of growth as compared to the susceptible biotype. Higher amylase activity is observed in the initial hours of imbibition in the resistant biotype. In the susceptible biotype it is activated at a much later stage.
Despite the increasing biological and economic impacts of invasive species, little is known about the evolutionary mechanisms that favor geographic range expansion and evolution of invasiveness in introduced species. Here, we focus on the invasive wetland grass Phalaris arundinacea L. and document the evolutionary consequences that resulted from multiple and uncontrolled introductions into Nort...
—Phalaris arundinacea L. (reed canarygrass) is an aggressive graminoid species that invades wetlands in much of the northern United States. In areas previously used for agriculture and other recently disturbed habitats, P. arundinacea out-competes the native flora and creates monocultures, which reduce biodiversity and alter ecosystem functioning. Much research has focused on the growth respons...
Little seed canary grass (Phalaris minor L.) is a major weed in wheat fields in some parts of Iran. To evaluate the efficacy of molecular and greenhouse methods in detecting the resistance of 49 biotypes of canary grass(Phalaris. Spp) to acetyl-CoA carboxylase-inhibiting herbicides, two methods including whole plant screening and PCR-based molecular methods were applied. Results showed that the...
چکیده وجود تنوع در منابع کشت و زرع ازجمله علوفه یکی از راهکارها در نیل به کشاورزی پایدار است. درمجموع تعداد 64 توده از گرامینههای علوفهای: Bromus، Dactylis، Festca، Phalaris و Poa در مزرعه تحقیقاتی در کرج کشت و صفات زراعی– مورفولوژیکی هر توده طبق دستورالعملهای استاندارد یادداشتبرداری گردید. تنوع خوبی برای بیشتر صفات در هر محصول و در کل کلکسیون دیده شد. آزمون F برای بیشتر صفات زراعی در تجزیه...
