Effects of carbon dioxide and nitrogen fertilization on phenolic content in Poa annua L.
Different but partially overlapping hypotheses have been developed to predict the allocation of phenolics in elevated atmospheric CO(2). The carbon-nutrient balance hypothesis predicts increased allocation to phenolics due to reduced relative availability of nitrogen. The growth-differentiation balance hypothesis states that allocation will depend on source and sink strength, while the protein ...
متن کاملControlling Annual Bluegrass (Poa annua L.) Summer Patch Disease with Faeriefungin

متن کاملReducing brown ring patch severity on Poa annua greens
We have conducted joint research studies on the management of brown ring patch since 2010. From a feld research perspective, this disease has been challenging to work with because it is diffcult to fnd naturally infected putting greens with uniform disease incidence and severity. The main body of research presented in this paper comes from work conducted in 2010 and 2011 on a putting green in N...
