In plants, an increasing interest for the comet assay was shown in the last decade. This versatile technique appears to be promising to detect the genotoxic effect of pollutants and to monitor the environment. However, the lack of a standardised protocol and the low throughput of the assay limit its use in plants. The aims of this paper are to identify key factors affecting comet assay performa...

A moderate-density linkage map for Lolium perenne L. has been constructed based on 376 simple sequence repeat (SSR) markers. Approximately one third (124) of the SSR markers were developed from GeneThresher libraries that preferentially select genomic DNA clones from the gene-rich unmethylated portion of the genome. The remaining SSR marker loci were generated from either SSR-enriched genomic l...

Lolium perenne L. commonly known as “ray grass” is a temperate grass species used pasture for livestock. perennen belongs to family Poaceae and perennial herb. It has great economic importance owing its suitability forage grass. cultivated in fields feed However, current study focuses on uncultivated Ray widely distributed fields, mostly found moist places, banks of stream, pastures etc. Farmer...

The biological value of fodder is estimated on the basis of its content of particular macroelements (N, P, K, Ca, Mg). Concentration of these components in fodder depends on many factors, mainly on the properties of soil, type of land use and growth phase of crops. The aim of this paper was to estimate the effect of soil properties, land use and species composition of a sward mixture on the con...

abstract turf grass as a main grown cover plant has a unique place in green space planning. in order to study the effect of hydrogel and paclobutrazol on water requirement of turfgrasse (lolium perenne l. barbal) a factorial experiment based on a brcd with 3 replication was conducted in the summer of 2010 in mashhad. the factors under study were 4 levels of hydrogel (0, 3, 6, 9 gr/kg soil), 3 l...
