Studies examined the possibility that mixtures of endophytic perennial ryegrass and Kentucky bluegrass provide resistance against larvae of the black cutworm, Agrotis ipsilon (Hufnagel). We hypothesized that resistance against A. ipsilon in such stands would stem from the influence of Kentucky bluegrass on A. ipsilon growth and behavior rather than the influence of endophytic perennial rvegrass...

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...

Multiple mechanisms of resistance to glyphosate are exhibited by populations of Lolium spp. worldwide. Association of resistance with growth and reproductive fitness is an important predictor for long-term success of glyphosate-resistant (R) versus glyphosate-susceptible (S) biotypes. Numerous studies were conducted on R- and S-biotypes of Italian ryegrass (Lolium multiflorum) and perennial rye...

Pediococcus lolii NGRI 0510Q(T) was isolated from ryegrass silage produced on Ishigaki Island, Okinawa Prefecture, Japan. Here we present a draft genome sequence for this strain, consisting of 103 contigs for a total of 2,047,078 bp, 2,154 predicted coding sequences, and a G+C content of 42.1%.

from Lolium perenne, Olea europaea, Artemisia vulgaris, Parietaria judaica and Platanus acerifolia.(Figure 1). Oral challenge test with raw cardoon produced pruritus in mouth and lips swelling 30 min after the ingestion whereas oral challenge with cooked cardoon did not produce any kind of symptomatology. We report a case of cardoon allergy confirmed by positive results in in vivo and in vitro ...

We have assessed the utility of morphological and microsatellite markers for tracing field hybridization between Lolium multiflorum and Lolium perenne in cereal-enclosed gene flow plots. The presence of awns on the inflorescence of F(1) hybrids was found to be a reliable, but underscoring, indicator of L. multiflorum paternity in L. perenne derived seed as determined by inheritance of species-s...

Three sludge types from the same treatment stream (undigested liquid, anaerobically digested liquid and dewatered, anaerobically digested cake) were used in a field based tub study. Amendments (4, 8, and 16 Mg dry solid (ds)ha(-1)) were incorporated into the upper 15 cm of a sandy loam soil prior to sowing with rye-grass (Lolium perenne L.). Nitrogen transformations in the soil were determined ...

A single chromosome of the grass species Festuca pratensis has been introgressed into Lolium perenne to produce a diploid monosomic substitution line 2n = 2x = 14. The chromatin of F. pratensis and L. perenne can be distinguished by genomic in situ hybridization (GISH), and it is therefore possible to visualize the substituted F. pratensis chromosome in the L. perenne background and to study ch...
