successful pasture-based milk production systems pivot on balancing dairy cows’ feed requirements with seasonal and annual fluctuations in pasture production. in order to maximise cow production from grazing dairy systems, it is necessary to reach an efficient utilization of grazed grass for feeding cows and the development of appropriate grazing management systems designed to maximize daily pa...

background and objectives: cold stress is one of the most important limiting factor for growth and development of grasses in temperate regions. freezing tolerance is highly different between plant species and between regions. the importance of grasses is due to widespread application in lawn beautifying, animal feeding, and erosion control. there are many differences between grass species in re...

information on quality characteristics of forage species help the range managers to select a suitable grazing program that minimizes the damages to vegetation. water soluble carbohydrates (wsc) -the main photosynthetic products- are stored in various plant parts and are more likely to be consumed when plants require them. in order to investigate the changes of wsc in distinguishable organs in t...

The reverse genetics detection of single base changes in genes of interest, whether induced or endogenous, is an extremely powerful tool for functional genomics. Two major thrusts of research in the grasses are characterizing the function of all the genes in various genomes and then comparing those functions among species. Targeting Induced Local Lesions IN Genomes (TILLING) has proven to be a ...

BACKGROUND Grasses release the most widespread aeroallergens with considerable sensitization rates, while different species produce several pollen concentration peaks throughout the season. This study analyzed the prevalence of grass species in three different European city areas and compared the flowering period of these species with daily pollen concentrations and the symptom loads of grass p...

Grass carp is an herbivorous species, which is actually popular in Iran. Monogenean parasites, particularly members of the family Dactylogyridae, have been one of the main causes of mortalities in Iranian fish farms and therefore they have been subject of many studies in Iran. The main aim of the present study was to describe morphological and molecular characteristics of monogenean parasites r...

Plants are the essential factors shaping soil microbial community (SMC) structure. When most studies focus on the difference in the SMC structure associated different plant species, the variation in the SMC structure associated with phylogenetically close species is less investigated. Legume (Fabaceae) and grass (Poaceae) are functionally important plant groups; however, their influences on the...
