This experiment was conducted to determine allopathic effects of Cyperus rotundus extracts on the tomato germination. It was a completely randomized design (CRD) with four replications, carried out in the laboratory of the Agricultural College of University Jiroft during 2011. The various test treatments were extracts of Cyperus rotundus taken from aerial organs, root, and com...
Nowadays, the root characteristics as one of secondary traits along with grain yield are used to response evaluation of rice genotypes under deficit irrigation. Thus, to evaluate the root traits of 40 irrigated rice genotypes to water limited condition a pot experiment was performed in 2014 at Rice Research Institute (Rasht), Iran. Irrigation treatment was applied in two levels include con...

the aim of this study was to identify the effect of spermine and salicylic acid on several growth parameters, such as shoot length, shoot fresh and dry weights, amount of protein and carbohydrate, of badami and qazvini pistachio cultivated variety under copper stress. the experiment design was completely randomized with three replicates per treatment and four levels of copper (o.5, 30, 45, 60 µ...
Silicon (Si) has not been considered as an essential nutrient for plant growth however, it has been shown that supplying crops with adequate Si can improve environmental stress tolerance. On the other hand, exposure to toluene, as a hazardous organic pollutant widely found in the water resources, is an environmental stress for plants growing around many industries. The aim of this nutrient solu...
the response of tomato genotype cal-ji against five salinity levels (distilled water as control, 25, 50, 75 and 100 mm) were studied at germination and early seedling stages. an experiment with conducted by using a completely randomized design (crd) with three replications. shoot and root length, shoot and root fresh weight, seed vigor, mean germination time, germination percentage and rate me...
Shoot tips of two fig cultivars (Conadria and Black Mission) proliferated in vitro, were cultured on modified MS medium supplemented with 0.5 mg/l 6-benzylaminopurine (BAP). The present investigation aimed to investigate the effect of different medium salt strengths (Double, full, half and quarter) and different sources of carbon (sucrose and fructose) at different concentrations (0.1 and 0.2 m...
in a greenhouse experiment, the effects of waterlogging, sewage sludge and manure on the uptake and concentrations of p, k, ca, mg and na in root and shoot of sunflower (helianthus annuus l.) were investigated. a factorial experiment based on completely randomized design with three replications including duration of waterlogging at five levels (0, 2, 4, 8, 22 days), source of organic fertilizer...
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...
Effect of drought stress and mycorrhizal symbiosis on growth and phosphorus (P) uptake by two sorghum cultivars different in root morphology was studied in a pot experiment. A factorial experiment with a randomized complete block design was performed. In this study, sorghum speed feed cultivar with high root proliferation and branching and sorghum KFS2 cultivar with low root proliferation and b...
