Morphological Diversity Assessment of Five Populations of Sulla (Hedysarum flexuosum L.) Harvested at Five Phenological Stages in Kabylie region (Algeria)
Hedysarum flexuosum L. is an important forage legume with high nutritive value. The determination of forage production in natural habitats is the most important factor for grazing management. Studies on its habitat characteristics and distribution are scarce. This research was conducted in order to evaluate the extent of pheno-morphological diversity in natural populations of Hedys...
متن کاملEffects of potassium on temporal growth of root and shoot of wheat and its uptake in different soils
In a pot culture experiment, the root length density, potassium concentration in crop, and total K uptake by wheat (Triticum aestivum var. HD 2285) at different growth stages (CRIS-Crown Root Initiation Stage, MTS-Maximum Tillering Stage, FLS-Flag Leaf Stage and DFS-Dough Formation Stage) were determined. Wheat crop was grown in 72 pots containing 4.5 kg of three types of soils, namely Alfisol,...
متن کاملO-8: Critical Role of Hyaluronan System in Pre-Implantation Embryo Development and Establishment of Pregnancy
Background: Hyaluronan (HA) is a structural component of extracellular matrix synthesised by HA synthases HAS1-3, which produce HA of different molecular sizes with distinct biological functions associated with reproductive processes. Hyaluronidase (HYAL) cleaves the HA into biologically active small fragments which are known to regulate cell proliferation through CD44 receptor signaling. HA is...
متن کاملComparison of optic lens proteins among animals at different stages of development
The purpose of this investigation was to study and compare the electrophoretic patterns of optic lensproteins of different species of domestic animals at pre- and post-natal ages. Optic lenses were removed from the embryo or adult sheep, cattle, goat, camel and chicken at the slaughter-house then homogenized and subjected to sodium dodecylsulfate polyacrylamide gel electrophoresis (SDS-PAGE). I...
متن کاملDistribution Patterns and Endemism of the genus Onosma L. (Boraginaceae) in Central Alborz
The evaluation as well as data banking of distribution patterns are considered as the most important management action for the conservation of biodiversity. Iran is considered as one of the most important of diversity centers of Onosma L. and includes a high rate of endemism. Due to the lack of adequate data on conservation and distribution patterns of the genus at local scale, the current stud...
