Effects of different levels of osmotic potential on germination percentage and germination rate of barley, corn and canola. Bagher Gharoobi1, Meysam Ghorbani2 and Mostafa Ghasemi Nezhad2
Iran is located in a hot and dry region. As a result of low precipitation and a vast area of salty and alkali soil, osmotic pressure is very high in most parts of the country (i.e., osmotic potential is more negative). In the present study four levels of osmotic pressure (-0.25, -0.35, -0.45, -0.50 MPa) were created artificially, by polyethylene glycol (PEG) and treatment of three seed types, n...

In Vitro Anthelmintic Effects of Senna Occidentalis (l.) Link (leguminosae) on Rat Tapeworm Hymenolepis Diminuta
Objective: This study was conducted to evaluate the anthelmintic activity of ethanolic leaf extract of Senna occidentalis on rat tapeworm Hymenolepis diminuta. Methods: Adult H. diminuta worms were obtained from laboratory maintained infection in rats. Different concentrations of crude ethanolic leaf extracts of S. occidentalis were tested in vitro on H. diminuta and praziquantel (PZQ) was used...
متن کاملThe effect of germination temperature on antioxidant enzymes activities and seed germination of Prangos ferulacea Seeds harvested at different seed moisture content
Prangos ferulacea is a plant from the umbeliferae family that is propagated by seed germination. In order to investigate the effects of seed ripening and germination temperature on germination and some antioxidant enzymes activity of this plant seed, a two-factor factorial experiment was carried out in a completely randomized design with three replications in the laboratory of Seed Sciences and...
متن کاملEffect of Seed Coating Methods on Germination Speed of Onobrychis sativa at Different Drought Stress Levels and Sowing Depths
Seed enhancement methods are applied to eliminate or decrease adverse environmental stresses effects and increase seed germination rate and vigor of rangeland plants. The aim of this study was to assess different methods of seed coating effects on germination speed of Onobrychis sativa at different sowing depths and soil moisture levels. The experiment was conducted at growth chamber to apply a...
