Genetic variability of Mg, Ca, and K in crested wheatgrass
Increasing available Mg in crested wheatgrass (Agropyron spp•) could reduce the incidence of grass tetany (hyponsagnesemia) in ruminants glazing this forage. Raisins the Mg levels might be done through genetic processes if enough variation in ion concentration existed in the Agropyrons. The purpose of this study was to determine the genetic variation in Mg, Ca, and K concentrations in 2 crested...
متن کاملGenetic Variability for Mineral Element Concentration of Crested Wheatgrass Forage
Grass tetany is a complex metabolic disorder that causes substantial livestock production losses and deaths in temperate r gions of the world. It is caused by low levels of Mg or an imbalance of K, Ca, and Mg in forage consumed by animals. Development of grasses with improved mineral balance would be an economical means of minimizing losses from this malady. This study was conducted to determin...
متن کاملInvestigation of Genetic Variations among Crested Wheatgrass Species Base of Agronomical Traits and Total Leaf Protein
Genetic variations within the species of Agropyron desertorum and 2 varieties of A. cristatum subsp. pectinatum var. imbricatum and A. cristatum subsp. pectinatum var. pectinatum were studied using morphological traits and total protein profiles (with sodium dodecylsulphate polyacrylamide gel electrophoresis). An experiment was conducted in Research Institute of Forests and Rangelands (2012-201...
متن کاملResponse of Russian brome, crested wheatgrass and tall wheatgrass to annual precipitation and grazing management in a semi-arid area
Three grass species, Agropyron desertorum (Agde) and Agropyron elongatum (Agel) and recently, Bromus tomentellus (Brto) are mainly used for range improvement as mixed seeding in semi-arid areas of Iran. Because there is little information about management of these grasses, this study was conducted at the Sisab Research Station in northern Iran to evaluate their responses to grazing management a...
متن کاملUptake of nonylphenol and nonylphenol ethoxylates by crested wheatgrass.
Nonylphenol (NP) and other hydrophobic biodegradation intermediates of nonylphenol ethoxylate (NPE) surfactants have been identified in wastewater treatment biosolids. These biosolids often are land applied, but little is known regarding the potential uptake of biosolid-derived contaminants by plants. Hydroponic experiments, 11 to 14 weeks in duration, were conducted to examine the uptake and t...
