1. Productivity of orchard grass (Dactylis glomerata L.) alone and associated with perennial ryegrass (Lolium perenne L.) and white clover (Trifolium repens L.)
ABSTRACT The objective of this research was to evaluate the productive capacity of orchard grass alone and associated with perennial ryegrass and white clover sown at different proportions. Treatments consisted of the following associations and monoculture: 100-00-00, 70-20-10, 50-00-50, 40-40-20, 40-20-40, 20-70-10, 20-40-40, and 00-50-50% of orchard grass,

2. Influência de sistemas de rotação de sementes de gramíneas forrageiras temperadas na composição do banco de sementes invasoras no solo / Influence of temperate grass seed rotation systems on weed seed soil bank composition
Em consequência da mudança nas práticas agronômicas nos cultivos de gramíneas perenes para sementes no oeste de Oregon, EUA, sistemas alternativos de rotação estão sendo considerados com a finalidade de reduzir a infestação de plantas invasoras. De um modo geral, inexistem informações dos efeitos de práticas agronômicas alternativas e aplicaç�

3. A Terminal Flower1-Like Gene from Perennial Ryegrass Involved in Floral Transition and Axillary Meristem Identity1
Control of flowering and the regulation of plant architecture have been thoroughly investigated in a number of well-studied dicot plants such as Arabidopsis, Antirrhinum, and tobacco. However, in many important monocot seed crops, molecular information on plant reproduction is still limited. To investigate the regulation of meristem identity and the control

8. Fructans, But Not the Sucrosyl-Galactosides, Raffinose and Loliose, Are Affected by Drought Stress in Perennial Ryegrass
The aim of this study was to evaluate the putative role of the sucrosyl-galactosides, loliose [α-d-Gal (1,3) α-d-Glc (1,2) β-d-Fru] and raffinose [α-d-Gal (1,6) α-d-Glc (1,2) β-d-Fru], in drought tolerance of perennial ryegrass and to compare it with that of fructans. To that end, the loliose biosynthetic pathway was first established and shown t

9. Endophytic Fungi in Indigenous Australasian Grasses Associated with Toxicity to Livestock
Grazing of Echinopogon spp. by livestock in Australia has caused symptoms similar to those of perennial ryegrass staggers. We observed an endophytic fungus in the intercellular spaces of the leaves and seeds of New Zealand and Australian specimens of Echinopogon ovatus. Culture of surface-sterilized seeds from New Zealand specimens yielded a slow-growing fun

10. Uptake and Assimilation of NO3− and NH4+ by Nitrogen-Deficient Perennial Ryegrass Turf
Assimilation of NO3− and NH4+ by perennial ryegrass (Lolium perenne L.) turf, previously deprived of N for 7 days, was examined. Nitrogen uptake rate was increased up to four- to five-fold for both forms of N by N-deprivation as compared to N-sufficient controls, with the deficiency-enhanced N absorption persisting through a 48 hour uptake period. Nitrate,

11. Ruminococcus flavefaciens Cell Coat and Adhesion to Cotton Cellulose and to Cell Walls in Leaves of Perennial Ryegrass (Lolium perenne)
Ruminococcus flavefaciens was shown to possess a prominent glycoprotein coat, which contained rhamnose, glucose, and galactose as its principal carbohydrates. Periodate-reactive carbohydrate occurred as a surface layer of the coat. The ruminococci adhered strongly by means of this coat to cotton cellulose and to cell walls in leaf sections of Lolium perenne

12. Origin of a Fungal Symbiont of Perennial Ryegrass by Interspecific Hybridization of a Mutualist with the Ryegrass Choke Pathogen, Epichloe Typhina
Seed-borne fungal symbionts (endophytes) provide many cool-season grass species with biological protection from biotic and abiotic stresses. The endophytes are asexual, whereas closely related sexual species of genus Epichloe (Clavicipitales) cause grass choke disease. Perennial ryegrass (Lolium perenne) is a host of two endophyte taxa, LpTG-1 (L. perenne en
