A major problem of arid and semi-arid regions is environmental stresses like salinity and drought. To study the effect of Artichoke germination under different levels of salinity and drought, two separate experiments were performed. The experimental treatments included different salinity levels of NaCl (0, 50, 100, 150 mM) and five drought levels by PEG (0, 10%, 15%, 20% and 25%) with three rep...

in order to evaluate the effects of wastewater irrigation on sugar content and morphological traits of sugar beet (beta vulgaris l.), an experiment was conducted in split plot design based on randomized complete block design with three replications at research station in shahrekord university in 2013. the treatments consisted of irrigation with urban wastewater at 2-4 and 8-12 leaf stages, and ...

in order to study the effect of intensity and exposure duration magnetic field on wheat (triticum aestivum l.) seed germination an experiment was conducted in laboratory of ferdowsi university of mashhad, iran. the experiment was including 11 treatments as three level of magnetic field intensities (pretreatment of seeds with 50, 100 and 150 mt magnetic field) and three exposure durations (10, 2...

The aim of this study was to determine the relationship between shoot nitrate concentration, mediated by nitrate supply to roots, and root exudation from Hordeum vulgare. Plants were grown for 14 d in C-free sand microcosms, supplied with nutrient solution containing 2 mM nitrate. After this period, three treatments were applied for a further 14 d: (A) continued supply with 2 mM nitrate (zero b...

Rooted stem cuttings of ‘Green Giant’ arborvitae (Thuja L. x ‘Green Giant’) were grown in 3.8 liter (#1) plastic containers containing a pine bark:sand (8:1 by vol) substrate. Plants were fertilized three times weekly for 15 weeks with a complete nutrient solution at N application rates (NARs) of 0, 10, 20, 40, 80, 160, or 320 mg/liter (ppm) supplied as ammonium nitrate (NH 4 NO 3 ). Both shoot...

The Experiment with nutrient solution was conducted in the glasshouse of the University of Applied and life Science, Vienna, Austria to evaluate the effect of water stress on root and shoot development of seven tomato cultivars. The stress levels were 20, 25 and 30 minutes (withholding water) as low, medium and severe stress. The experiment revealed that the cultivars BR-4 and BR-5 showed compa...

The influence of different initial inoculum densities of the root-knot nematode Meloidogyne javanica on the growth of sage (Salvia officinalis), root-knot development and nematode multiplication was investigated 90 days after inoculation under greenhouse conditions. With the increase in the nematode initial inoculum densities, shoot fresh/dry weight, shoot/root length and root fresh/dry weight ...
