Annual ryegrass (Lolium multiflorum Lam.) and crimson clover (Trifolium incarnatum L.) were pulselabeled with C-CO2 in the field between the initiation of late winter growth (mid-February) and through flowering and seed formation (late May). Straw was harvested after seed maturation (July), and soil containing C-labeled roots and root-derived C was left in the field until September. C-enriched ...

Low temperature is one of the abiotic stresses seriously affecting the growth of perennial ryegrass (Lolium perenne L.), and freezing tolerance is a complex trait of major agronomical importance in northern and central Europe. Understanding the genetic control of freezing tolerance would aid in the development of cultivars of perennial ryegrass with improved adaptation to frost. The plant mater...

Pinus radiata D. Don is an important tree in New Zealand where it is widely grown for timber and, to a lesser extent, in association with pasture species. In pure stands of P. radiata in Canterbury, poor development of undergrowth may in part be caused by volatile inhibitory substances released from the decomposing litter. In previous work it was shown that vapour from incubated P. radiata litt...

Italian ryegrass (Lolium multiflorum Lam.) is one of the most important forage grass species in Europe. In Portugal 34% of the cultivated area is dedicated to animal fodder. Italian ryegrass area in Entre Douro e Minho (EDM) region was mainly with landraces. Changes in traditional agricultural systems are contributing to a major loss of genetic diversity mainly to landraces. Portuguese Italian ...

Trichoderma harzianum IS005-12 promotes germination, seedling growth and seedborne fungi suppression in Italian ryegrass forage | Nevena Banjac, Rade Stanisavljević, Ivica Dimkić, Nataša Velijević, Marina Soković, Ana Ćirić Agricultural Journals

The ryegrass mosaic virus (RgMV) is a single positive-strand RNA virus belonging to the genus Rymovirus. The major natural hosts for RgMV are members of the Gramineae species, including ryegrass. Here, we report the nearly complete genome sequence of RgMV by de novo assembly using ryegrass transcriptomes.

1. Five rumen-fistulated cows were given freshly cut ryegrass (Lolium perenne L.) and lucerne (Medicago sativa L.), on separate occasions, to compare rates of particle breakdown and aspects of rumen fermentation. 2. Cattle were required to consume their daily allowance (offered ad lib.) in two 2 h feeding periods daily. 3. During the first 2 h feeding period, dry matter (DM) intakes of ryegrass...

In southeastern regions of the US, herbage systems are primarily based on grazing or hay feeding with low nutritive value warm-season perennial grasses. Nutritious herbage such as annual ryegrass (Lolium multiflorum Lam.) may be more suitable for preserving as baleage for winter feeding even with more intensive production inputs. Emerging in-line wrapped baleage storage systems featuring rapid ...

An experiment investigated whether the inclusion of chicory (Cichorium intybus) in swards grazed by beef steers altered their performance, carcass characteristics or parasitism when compared to steers grazing perennial ryegrass (Lolium perenne). Triplicate 2-ha plots were established with a chicory/ryegrass mix or ryegrass control. Forty-eight Belgian Blue-cross steers were used in the first gr...

Whole-genome sequences established for model and major crop species constitute a key resource for advanced genomic research. For outbreeding forage and turf grass species like ryegrasses (Lolium spp.), such resources have yet to be developed. Here, we present a model of the perennial ryegrass (Lolium perenne) genome on the basis of conserved synteny to barley (Hordeum vulgare) and the model gra...
