in order to evaluate the effect of zeolite application and selenium spraying on some physiological traits and grain yield in medicinal pumpkin (cucurbita pepo l.) under different moisture regimes, a study was conducted in a factorial experiment based on randomized complete block design with three replications during 2010 in takestan at gazvin province, iran. the three levels of irrigation facto...

the impacts of salicylic acid and silicon on some physiological parameters of maize seedlings in the presence ofcadmium (100 μm) were investigated. inhibitory effects of cadmium on seedling growth resulted in reduced shoot and root fresh weight, low percentage of relative water content, low chlorophyll, free proline and soluble sugars contents and a low rate of lipid peroxidation. results indic...

to evaluate the effect of slow release fertilizer and humic acid on quality of new guinea impatiens (impatiens hawkeri), an experiment established in complete random design with 15 treatments and three replications. treatments were slow release fertilizer (12-11-18-2.7mgo-8s) in five levels (0, 1.5, 3, 4.5 and 6 kg/m3) and humic acid in three levels (0, 2 and 4 kg/m3) that mixed with medium cul...

Silicon is known to ameliorate the deleterious effects of drought on plant growth. We evaluated growth of wheat (Triticum aestivum L. CV. Chamran) under Water-Deficit Stress Induced by Polyethylene Glycol as affected by Si application. In this article, the effects of Si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (RWC), electrol...

Salinity of soil is a major abiotic stress limiting the crop production and growth of peppermint. The aim of study was assessment the plant growth regulators efficacy (salicylic acid (SA), jasmonic acid (JA), brassinosteroids (BRs), and non-application of hormone as control) on physiological traits of peppermint under salinity stress (0, 30, and 60 mM). The experiment was conducted using the co...

this study was carried out to evaluate the changes in some important cell parameters under water limitation in sorghum genotypes. a factorial experiment was conducted based on randomized completely design in greenhouse, in university of mohaghegh ardabili in 2014. treatments were water stress at levels of 85, 65, 45 and 25 percent field capacity in and three genotypes of forage sorghum (kfs2, k...

boron toxicity is becoming more extensively widespread in arid and semi arid regions, due to the application of either saline waters or irrigation waters containing a relatively high b content. results of research indicate that addition of certain plant nutrients such as n may reduce the harmful effect of high b levels. therefore, the present experiment was undertaken to evaluate the interactiv...
