  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...

     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...

A soil contaminated by 10,000 ppm of gasoline (GAS), is a concentration higher than the limit 4,400 established Mexican standard NOM-138-SEMARNAT/SSA1-2003. In soil, it inhibits mineralization organic matter causing loss fertility. Therefore, aims this research a) biostimulation impacted GAS, and b) phytoremediation through Zea mays enhanced with Azotobacter vinelandii to decrease GAS value low...

Potato (Solanum tuberosum L.) has relatively weak root system and requires high nitrogen fertilizer which is costly and may pose environmental pollution. This study was conducted to compare root morphological characteristics and nitrogen uptake of some potato cultivars growing in Iran. A greenhouse experiment using a completely randomized design with 3 replications and 8 potato cultivars includ...

Although red cell distribution width (RDW) and P-wave dispersion (Pwd) are strong independent predictors of atrial tachyarrhythmia (ATa), the association between these two factors in the occurrence of ATA has hitherto not been reported. We retrospectively analyzed the cases of ATa patients who underwent Holter monitoring at our hospital from October 2013 to August 2014. Clinical data including ...

In order to study the effect of zinc (Zn) nutrition on relative tolerance of olive (Olea europea L.) seedlings to salinity, a factorial pot experiment was conducted, based on completely randomized design with three replications, during fall 2013. One-year seedlings of two olive cultivars (‘Frontoio’ and ‘Conservolea’) were planted in 10-litre plastic pots containing sand and perlite (1:1 ratio)...

The use of recent technologies for the increase of growth indexes and the plants yields is an important aspects and till now many research works for this has been done. One of these efforts is the usage of magnetic water and zeolite for the increase of yield plants. This research work is an study on the effects of magnetic water and zeolite that has been done on frame work of pore random design...
