Ornamental plant species may vary substantially in their tolerance response to heavy metals. The aim of this research was check chrysanthemum cultivars, namely Donglin Ruixue (C), Yellow (F), Red pocket (G), and New 9714 (I), which are commonly used as landscape plants determine levels cadmium (Cd) at different concentrations through hydroponic cultures. Chrysanthemum cultivars were treated wit...

To study the effect of different concentrations of potassium in thenutrient solution and water stress on the quality and quantity yield of Lilium LA cv.Termoli, a pot experiment was conducted based on completely randomized design in sand and perlite medium (50:50) in three levels of potassium (Kfree, 6 mM K and and 12 mM K in Hoagland solution) with three replications. In the present study, the...

Concentrations of heme b were determined in a mesocosm experiment situated in Gullmar Fjord off Sweden. The mesocosm experiment lasted for ca. one hundred days and was characterised by the growth of a primary nutrient replete and a secondary nutrient deplete phytoplankton bloom. Heme b varied between 40 ± 10 pmol L-1 in the prebloom period up to a maximum of 700 ± 400 pmol L-1 just prior to the...

The objective of this study was to investigate the effects of foliar applications of potassium and zinc on the fruit yield and quality as well as leaf nutrient concentrations of pistachio cv. ‘Chrokeh’. The experiment was conducted based on a completely randomized block design with nine treatments and three replications per treatment. Treatments were three levels of K2SO4 (0, 1 and 2%) and thre...

Background & Aim: The pigments inside the leaf chloroplasts receive sunlight energy and transport it to photosynthesis reaction center. The most important of these pigments is chlorophyll. In this study, the pigments existence in medicinal plant, sumac (Rhus coriaria L.), was investigated at Biotechnology Laboratory, Isfahan University of Technology. Experimental: Experiments were per...

this research investigate the effects of different concentrations of salt: 0, 75, 100, 150 (mm nacl) and concentration of 0.05 mm gibberellic acid and 5µm salicylic acid on the content of proline and a, b chlorophylls of canola (hayola 401 and rgs). the results showed that with increasing in the amount of salinity in both chlorophylls decreased and the amount of decrease in chlorophyll b was mo...
