Changes in voluntary feed intake (VFI) and average daily gain (ADG) of 10to 12-month-old male red deer (Cervus elaphus) in response to a range of pasture morphological development stages of perennial ryegrass (Lolium perenne L.) and white clover (Trifolium repens L.) pasture in spring were investigated. An intake study in November 2000 tested responses to pastures spelled for 6, 8 or 10 weeks i...

Rigid ryegrass (Lolium rigidum) is one of the most troublesome weeds in different crops in the Mediterranean region. A rigid ryegrass biotype from an olive grove in Jaén province (Andalusía, southern Spain), potentially resistant to glyphosate (RG), was tested for its resistance level through dose-response assays using a susceptible biotype (SG). To test the hypothesis of a non-target-site-base...

abstract the lack of water is the most important problem in extensive landscape especially turfgrass in arid and semi arid regions. the root responses in native and commercial grasses under drought stress were investigated. this experiment was in a factorial experiment based on unbalanced completely random design on the year 2006. the specious that we used in this experiment included (i) commer...

BACKGROUND AND AIMS To address the issues associated with food security, environmental change and bioenergy in the context of crop plants, the production, identification and evaluation of novel plant phenotypes is fundamental. One of the major routes to this end will be wide hybridization and introgression breeding. The transfer of chromosomes and chromosome segments between related species (ch...

Meadows on organic soils perform an essential role as a source of fodder and biomass for energy purposes. In the case intensive meadows, it is crucial to use grass mixtures that enable obtaining high yields good quality; however, soils, species composition changes dynamically. We carried out full cultivation (ploughing) grassland restoration. The floristic meadow sward in first year (2013) was ...

The aims of the study were to determine group specificity in microbial utilization of root-exudate compounds and whole rhizodeposition; quantify the proportions of carbon acquired by microbial groups from soil organic matter and rhizodeposition, respectively; and assess the importance of root-derived C as a driver of soil microbial community structure. Additions of 13C-labelled root-exudate com...

Detached 3-week-old leaves of Agrostis palustris, Lolium perenne, Poa annua, and Poa pratensis were inoculated with conidial suspensions of two isolates of Colletotrichum graminicola obtained from A. palustris. Inoculated leaves were incubated at 23 degrees C under high relative humidity (>95%). The infection process was investigated by light microscopy from 2 to 168 h after inoculation (AI). S...
