The aim of the present study was to determine effects of artificial drought stress on the characteristics of germination and seedling growth in bread wheat cultivars. The material of experiment consisted of seeds obtained from eight bread wheat cultivars with different response to drought (Alpu 2001, Sultan 95, Konya 2002, Eser as sensitive cultivars; Karahan 99, Tosunbey, Kate A1 as resista...
Cadmium (Cd) pollution is a major environmental and human health threat. Therefore there is a need for cost-effective remediation procedures. Chelators such as humic acid have shown positive effects in enhancing resistance to various stresses. The objective of this research was to investigate the use of humic acids at cadmium-contaminated soil on growth and soluble sugar concentration of aloe v...
Parameters that show a significant genotypic variation at early growth stages and are associated with salt tolerance at later stages may be used as rapid and economic screening criteria in breeding programs. The objective of this study was to test growth parameters at early growth stages for evaluating the salt tolerance of wheat genotypes. Ten wheat genotypes that differ from their salt tolera...
To study drought stress on seedling dry weight, proline contents and evaluate of antioxidant enzymes activity in canola genotypes (Brassica napus l.), an experiment were evaluated at laboratory physiology, Shahed University. This experiment was carried out in factorial with CRD design with 4 replications in 2008. The first factor was including levels of dough stress, one without stress as check...
In order to assess the effects of salt stress on some morphological traits of tolerant and sensitive cultivars of wheat (Triticum aestivum L.), a factorial experiment, based on completely randomized design in 3 replications, was conducted under greenhouse condition. The first factor was two genotypes of Sistani and Neishabour (tolerant cultivars) and two genotypes of Tajan and Bahar (sensitive ...
in this study the response of 9 rapeseed genotypes were evaluated at the seedling stage using different irrigation levels (50, 70 and 100% fc). a factorial experiment based on rcbd was conducted in the research greenhouses of urmia university with four replications during summer of 2013. some physiological traits such as relative water content, stomatal conductance, transpiration, photosynthesi...
Biochar reduces the bioavailability of a wide range of pollutants, especially heavy metals (HMs).To evaluate the effects of waste biochar of cutflower rose on growth characteristics and accumulation of lead (Pb) and cadmium (Cd) HMs of in lettuce, a factorial experiment, based on completely randomized design, with four replications was conducted. The amount of rose biochar at 3 levels (0, 5 and...
This study was carried out in two separate experiments in order to evaluate the responses of different safflower (Carthamus tinctorius L.) genotypes to salinity at germination and vegetative growth stages. In both experiments, thirteen safflower genotypes were investigated under non-saline and saline conditions (100 mM sodium chloride). Germination experiment was done in the seed laboratory and...
Considering the effect of salinity stress on the quantitative and qualitative traits of sugar beet genotypes, it seems necessary to study the response of genotypes obtained from breeding programs to salinity stress. For this purpose, 17 full-sib genotypes (derived from sibling crossing) with 7 different tolerant control under two salinity stress (electrical conductivity 17.36 dsm) and without s...
In Iran, Acacia victoriae is not native to tree in Iran but it is used for important goals such as stabilize hills and the beautify landscape in the southern regions of the Iran, especially in the Khuzestan and Ilam provinces. Researches that include the development of native and non-native trees, which are compatible with the conditions of dusting areas in the western provinces of Iran, are ve...
