The yield of a pasture is directly proportional to the amount light plants intercept and allocate different organs. When are carbon (C) limited, due defoliation, they more C preferentially shoots restore leaf area. In contrast, water nitrogen (N) limitations lead greater allocation roots. Changes in root:shoot ratio therefore reflect changes N partitioning indicate their relative priority. A ma...

OBJECTIVE We conducted a large observational study in 193 children and adolescents with allergic rhinitis due to grass or tree pollens to evaluate the safety and tolerability of an ultrarush high-dose sublingual immunotherapy (SLIT) regimen reaching a maintenance dose of 300 index of reactivity within 90 minutes. METHODS Children and adolescents aged 5 to 17 years with at least a 1-year medic...

The method described in the present work allows the purity of the solution under test for tocopherols to be assessed and also enables the separation of the commonly occurring a-, yand 8-tocopherols to be achieved. Applications of the method to the examination of several oils indicate the usefulness of the method. For example, the presence of 8tocopherol in soya-bean oil is readily ascertained, ...

The objective of this study was to determine the specific methane yields of four grass species (cocksfoot, tall fescue, reed canary grass and timothy) cultivated under boreal conditions as well as how harvesting time and year of cultivation affects the specific methane yields per ha. The specific methane yields of all grasses and all harvests varied from 253 to 394 Nl CH4/kg volatile solids (VS...

Because of the growing number of pasture cultivars used in N.? and the drfficulty of rekably separating cultivars of the same species by morphologrcal characters, seed protein banding patterns have become a useful supplementary means of cultivar identrfrcation for the purposes of seed certiftcation and plant variety rights appkcations. Sodium dodecylsufphate polyacrylamide gel electrophoresis o...

The aim of this study was to determine the effects pasture (cocksfoot cv. porto (CFP) and lucerne) supplementation grazing lambs with pellets or without plant oil infusion on performance carcass characteristics. Forty-eight White Suffolk x Corriedale first-cross weaners were randomly assigned one four treatments in a split-plot experimental design: (1) CFP lucerne pastures only (control); suppl...
