A pot experiment was conducted in a completely randomized design with five treatment and five replication, in each replication were 6 plants used. The study of zinc sulphate (ZnSO4) application (20 and 40 ppm) and Salicylic acid (SA) application (50 and 150 ppm) was compared to the control (distillated water) on growth and flowering Petunia hybrid. For each plant was used 10...

Previous studies have shown that salicylates can change the ion permeability of root cells. Therefore the possible effects of exogenous salicylate application on lead (Pb) and copper (Cu) accumulation and its protective role against DNA damage due to metal exposure in Lemna gibba were studied. L. gibba was exposed to 5, 10, and 25 microM Pb and Cu for six days in the presence and absence of sod...

background: satureja khuzistanica jamzad, with the common persian name “marzeh khuzestani”, is an endemic medicinal plant, distributed in the southwestern areas of iran. salicylic acid (sa) is a signaling molecule and a hormone-like substance that plays an important role in the plant physiological processes. objective: this study was conducted to determine the influence of foliar sa application...

Residues of khat (Catha edulis Forskal) leaves in the soil showed an inhibitory effect on the dry mass, pectin and cellulose of wheat shoots and roots and cell wall-associated proteins of roots. The dry mass of shoots and roots significantly reduced and the reduction in roots was greater than in shoots. On the other hand, the contents of hemicellulose and lignin in both shoots and roots and cel...

The effect of exogenous application; seed priming or foliar spraying of salicylic acid (SA) on Yecora Rojo and Paragon wheat cv. under NaCl-salinity. Gas exchange parameters, growth parameters, yield and yield components were reduced in both cultivars under salinity stress with foliar spray and soaking seeds. Exogenous application of SA through foliar spraying or seed soaking showed a slight in...

Seedlings establishment at early growth stages of crop plants is severely affected by soil salinity. Therefore, high germination rate and vigorous early growth under salty soils is preferred. In this study germination and seedling growth of a wheat (Triticum aestivum L.) cultivar was assessed using three replicates of 50 seeds in a factorial laid out in two separate experiments as Completely Ra...

The possible alleviating effects of salicylic acid on protection of cowpea (Vigna unguiculata) cv. Parastu under water stress conditions were investigated in the University of Zanjan Agriculture Research Station during 2008. Water stress was imposed by withholding irrigation at 50% flowering (flowering water stress, FWS) and when 50% of the pods grew 2-3cm (pod-formation water stress, PFWS). Sa...
