A pot experiment was conducted to evaluate the effect of synthetic wastewater containing various concentrations of cadmium and chromium on Eucalyptus camaldulensis. Six month-old seedlings of E. camaldulensis were treated with Cd (II) and Cr (VI) for 18 months. Treatments were; T0: (Tap water, control), T1: 0.05 +1.0 mg L, T2: 0.10+2.0 mg L, T3: 0.20+4.0 mg L and T4: 0.40+8.0 mg L of Cd and Cr ...
This experiment was conducted in a greenhouse at Isfahan University of Technology, Isfahan, Iran in 2014 to evaluate 20 wheat cultivars (Navid, Pishtaz, Karaj, Kavir, Tajan, Karun, sholeh, Bahar, Khoshki 11, Gasparood, Sepahan, Sorkh tokhm, Chamran, Ghods, Shariar, Omid, Sistan, Alamut, Marvdasht and Shiraz) under two carbon dioxide concentrations (the ambient 360 and the enriched 700 µM) and t...
To evaluate the effects of different levels of nitrogen (N) and salinity on yield and growth indices of tomato, a factorial experiment with a completely randomized design and three replications was performed in greenhouse conditions. Treatments included four levels of salinity (0.5, 2.5, 4.5 and 6.5 dS/m as NaCl) and four levels of N (0, 60, 120 and 240 kg/ha). The results showed that fruit yie...
In order to evaluate the effect of different levels of benzyladenine, nitrogen and salinity on growth characteristics of pistachio seedlings, cv. Badami Zarand, a factorial experiment with three factors: benzyladenine (0, 250 and 500 mg/L), nitrogen (0 and 100 mg N/kg soil as NH4NO3) and salinity (0 and 2000 mg NaCl/kg soil) was carried out as completely randomized design with three replication...
In recent decade, establish and maintenance of turf grasses is faced with serious doubts due to reduction of precipitation and water resources. So, identification of drought-resistant native and rangeland species, and introducing them as turf grass not only is effective in reducing water consumption, but also help to preserve the genetic resources of the country. In order to evaluate the usabil...
Research pertaining to genetic variability parameters, heritability, and genotypic, phenotypic, simple, and environmental correlations for various seedling traits in five elite advanced cotton (Gossypium hirsutum L.) lines (FH-113, FH-114, FH-941, FH-942, and FH-2015) and one check (CIM-496) was carried out during October and November 2010 under greenhouse conditions at the Cotton Research Inst...
This research was carried out to evaluate the effect of two mycorrhiza species on growth, yield and oil content of geranium under salinity stress. The experiment was done at research greenhouse of Faculty of Agriculture, Lorestan University, Iran, in 2014. Four levels of substrate (sterilised and non-sterilised control soil and sterilised soil inoculated with Glomus mosseae or G. intraradices),...
abstract application of salicylic acid (sa) as a phytohormone has been increased due to its role in plant tolerance to environmental stresses such as drought. the main goal of this experiment was to evaluate the effects of sa on morphological and physiological characteristics of cucumber seedlings under drought stress. a factorial experiment based on completely randomized block design was condu...
to evaluate the effects of various concentration of carbon dioxide and salinity stress on morphophysiological characteristics of amaranthus tricolor l. an experiment was conducted in greenhouse conditions in faculity of agriculture ferdowsi university of mashhad. the experiment was split plot based on completely randomized design with three levels of co2 (380, 700, 1050 µl/l) and three concentr...
Zinnia is an annual plant with the long flowering period from late spring to mid-autumn. It is a popular plant for landscape. In the present study, the effect of two types of growth promoting bacteria and Azolla compost on some ornamental characteristics of Zinnia were evaluated in pot cultivation and greenhouse conditions. The factorial experiment was conducted in three replications based on a...
