Substitution of a species or cultivar with higher uptake of an element by one with lower uptake has been proposed as a remediation strategy following accidental releases of radioactivity. However, despite the importance of pasture systems for radiological dose, species/cultivar substitution has not been thoroughly investigated for forage grasses. 397 cultivars from four forage grass species; hy...

BACKGROUND Grass pollen, in particular from Lolium multiflorum is a major allergen source in temperate climate zones of Southern Brazil. The IgE sensitization profile of Brazilian grass pollen allergic patients to individual allergen molecules has not been analyzed yet. OBJECTIVE To analyze the IgE sensitization profile of a Brazilian grass pollen allergic population using individual allergen...

Regulation of flowering time is best understood in the dicot model species Arabidopsis thaliana. Molecular analyses revealed that genes belonging to the MADS box transcription factor family play pivotal regulatory roles in both the vernalization- and photoperiod-regulated flowering pathways. Here the analysis of three APETALA1 (AP1)-like MADS box proteins (LpMADS1-3) and a SHORT VEGETATIVE PHAS...

Circular dichroism spectra of the arabinogalactan-protein from suspension-cultured Lolium multiflorum (ryegrass) endosperm cells demonstrate the presence of polyproline II conformation in the protein moiety of the proteoglycan. Subject to a number of theoretical and practical constraints of the method, it can be estimated that at least 30% of the protein component is in this conformation.

Groups of six to nine Merino Summary lambs were weaned in September (May drop) and December (September drop) on to three types of irrigated perennial pastureperennial ryegrass (Lolium perenne), Ladino white clover (Trifolium repens) and lucerne (Medicago sativa), and one irrigated annual pasture-subterranean clover ( Trifolium subterraneum) . The weight gain of the weaners on white clover was s...

BACKGROUND Plants can rapidly evolve resistance to herbicide in response to repeated selection. This study focuses on cross-resistance patterns observed in Lolium rigidum following pyroxasulfone recurrent selection. RESULTS The parental MR (multiresistant) population following four generations of pyroxasulfone recurrent selection evolved cross-resistance to prosulfocarb and triallate. At the ...

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...

The existence of a semipermeable layer in grass seeds has been extensively reported, yet knowledge of its influence on tests for seed viability and vigor that depend upon measurement of electrical conductivity (EC) is limited. This study determined the presence and location of the semipermeable layer, and its relation to seed viability and vigor assessment, in seeds of four important grass spec...

abstract little information is available concerning morphological responses of lolium perenne cultivars (numan and speedy green) to salinity and trinexapac-ethyl treatment in initial growth. in order to evaluate the effect of salinity treatment (0, 2000, 4000 and 6000 mg/lit) and trinexapac-ethyl levels (0, 50, 100 gr/ha) on morphological responses of 'numan' and 'speedy green' in initial growt...
