environmental stresses especially drought stress affect on the different aspects of plant growth and cause decrease and delay in germination, decrease of aerial parts growth and decrease in dry matter production. in order to study the effect of drought stress on germination and seedling growth of roselle (hibiscus sabdarifa) medicinal plant, this experiment was conducted in a randomized complet...

Reproduction and spawning patterns of the Yellowtail scad (Atule mate) were studied in the Persian Gulf and Oman Sea (Hormozgan coastal waters) from December 2016 to November 2017. A total of 447 fish were collected from Bandar Lengeh, Qeshm Island, Bandar Abbas, and Bandar Jask landing sites. Minimum and maximum fork lengths of this species were 10 and 33 cm, with average 20.63±1.73 cm. The to...

length weight relationships of vimba vimba persa were studied. for this purpose 174 fish samples were collected by gill nets, beach seine and purse seine from march through june 2008 at two guilan fisheries catch stations of guilan located in anzali- kiyashahr regions. samples were immediately transferred to the laboratory of fish biology at university of guilan for further analyses. length, we...

studies on the biometric parameters of a species to have an important role in its population or stock management and conservation. present study investigated the morphometric, meristic, length-weight relation (lwrs), length-length relation (llrs) and growth status (k and kn) of the redline torpedo barb, p. denisonii collected during august 2012 to july 2013 from river valapattanam, kerala. the ...

Silicon nanowire (SiNW) arrays were produced by electroless method on polycrystalline Si substrate, in HF/ AgNO3 solution. Although the monocrystalline silicon wafer is commonly utilized as a perfect substrate, polycrystalline silicon as a low cost substrate was used in this work for photovoltaic applications. In order to study the influence of etching time (which affects the SiNWs length) on d...

Effect of Seaweed Liquid Extract (SLE) of Caulerpa scalpelliformis on growth and biochemical constituents of Vigna mungo was studied. The lower concentration of SLE of C. scalpelliformis (25%) enhanced the percentage of germination, shoot length, root length and biochemical constituents viz., chlorophyll, carotenoid, amino acid, reducing sugar and total sugar contents and α-amylase and β-amylas...

in order to identification of allelopathic compounds and investigation of the effect of aerial part extract of orchard grass on germination and seedling growth of alfalfa an experiment conducted as completely randomized design with four replications at university of mohaghegh ardabili, iran. treatments were concentrations of orchard grass extracts including 0, 25, 50, 75, and 100%. radicle and ...

AbstractThis study was undertaken to better understand the probable mechanisms of salt stress tolerance induced by seed priming of salicylic acid (SA) in barley. The barley seeds were pre-soaked by SA or water and then sown under different saline watering regimes including 0.62 (tapwater), 5, 10 and 15 dS m-1 in petri dishes and trend of water absorbing, seedling growth, germination rate and pe...
