Studying of essential oil variations in leaves of Mentha species

  To evaluate the beneficial impacts of different species on mint, some yield characters were investigated. Our objective in this research was the studying of different species effects on essential oil variations. In this respect, the experimental unit had designed by achieved treatment in completely randomized block design with three replicates. The factor including mint species (Mentha longifolia var....

Analysis of phenanthrene biosorption to the roots of Cyperus hermaphroditus by microscopy, spectroscopy and photoacoustic techniques

  Understanding the process of contaminant accumulation by plants is essential to assessing crop contamination; organic chemicals may be adsorbed to roots and then be taken up, translocated, metabolized, or transpired by plants. The biosorption of phenanthrene by the radical system of Cyperus hermaphroditus,was studied by plants exposed to different concentrations of this pollutant, during 3 and 12...

Evaluation of cowpea genotypes for soil moisture stress tolerance under screen house conditions

  A potted experiment was conducted in a screen house at the University of Ilorin, Nigeria to evaluate the growth and grain yield responses of 10 genotypes of cowpea to soil moisture stresses. The experiment was designed as a 4 x 10 factorial and laid out in split-plots arrangement, evaluated ten genotypes of cowpea at four soil moisture stress levels with all factorial combinations replicated four times....
