rainfall deficiency and the development of salinity in iran are the most important factors for using new salt and drought-resistant plants instead of conventional crops. kochia species have recently attracted the attention of researchers as a forage and fodder crop in marginal lands worldwide due to its drought and salt tolerant characteristics. this field experiment was performed at the salini...

Invasive species that are closely related to each other may have similar population dynamics and, therefore, be controlled by targeting life stages. We studied two invasive knapweed species, spotted (Centaurea stoebe subsp. micranthos) and the hybrid meadow complex ( Centaurea × moncktonii ) in New York, USA, determine their individual growth rates (λ) across several sites over three years. Bot...

in this study, 40 genotypes and breeding lines in the vegetative stage was conducted in a factorial arrangement based on a complete randomized block design with 3 replications in greenhouse at sari university agricultural science and natural resource, iran, 2008. seventeen genotypes were selected and tested in seedling stage in 2009. the results showed that genotypes had significant difference ...

Unraveling the complexity underpinning nitrogen (N) use efficiency (NUE) can be physiologically approached via examining grain N sources and N internal efficiency (NIE) (yield to plant N content ratio). The main objective of this original research paper is to document and understand sorghum NUE and physiological mechanisms related to grain N dynamics. The study of different grain N sources, her...

1. The vegetative forms of amebae may be developed in vitro from the cysts. 2. The cysts of Entamoeba tetragena and Entamoeba coli each produce only a single vegetative individual. It has not been observed in vitro that a number of daughter amebae, corresponding to the number of nuclei present in the cyst, emerge from the mother cyst, as claimed by Casagrandi and Barbagallo, Schaudinn, and a nu...

Ocimum basilicum is a valuable source of bioactive metabolites with high preventive and therapeutic effectiveness. Here we aimed to investigate the effect phenological stages (vegetative flowering stages) on essential oil composition biological activities two varieties O. (Fino Verde variety Genovese varieties). To this end, level oils, flavonoids phenols, as well antioxidant antifungal were me...

Plasma membrane glycoproteins from Dictyostelium discoideum amoebae at three stages of early development were digested with Pronase and endoglycosidase H and fractionated by gel filtration. This gave three classes of glycans (polysaccharides, endoglycosidase H-resistant glycopeptides, and endoglycosidase H-released oligosaccharides), which were tested for their ability to block agglutination of...
