background & aim: ginger is common named zingber officinale roscoe. belongs to zingiberaceae family which extensively used to pharmaceutic industries in addition to food industries uses. dut to iran is located at world saline lands, salinity is a main problem to native and nonnative plant species cultivation such as ginger and because in plants salinity induces antioxidative and defensive s...
To study the effect of salinity on photosynthesis pigments, fluorescence and antioxidants of three varieties of peanut leaf as an indicator of resistance to salinity, research was carried out as factorial arrangement based on completely randomized design with three replications in the greenhouse of University of Guilan in 2013. The experiment consisted of a combination of 4 different salinity l...
In order to evaluate the effects of salicylic acid on some physiological characteristics of common purslane (Portulacea oleracea L.) under NaCl stress, a factorial experiment based on completely randomized design with three replications was conducted in 2013 in research greenhouse of Faculty of Agriculture, University of Yasouj, Iran. Treatments were included of six levels of NaCl salinity (0, ...
In order to study the effects of seed inoculation by cycocel and biofertilizers on yield, antioxidant enzymes activity and some biochemical traits of wheat (Triticum aestivum L.) under soil salinity condition, a factorial experiment was conducted based on randomized complete block design with three replications in a research greenhouse of Faculty of Agriculture and Natural Resources, University...
Soil salinity and compaction are probably the most prevailed limitations for crop growth and production. Their mitigation and control may be important crop management keys that can ensure yield sustainability and optimum use of land and water. This research was performed to investigate the combined effect of soil salinity and soil compaction on some growth characteristics of corn (Zea mays L.) ...
the aim of this study is investigating the effect of teaching “metacognitive strategies” on the way which scientific information retrieval workes by the using of google scholar searching machine on the students of ms in the psycology & education faculty of allameh tabatabayi university in 2007-2008 academic year. the statistical community was the students of ms in psychology & education facult...
introduction soil salinity is a major limiting factor in agricultural development within iran. nitrogen is the most important nutrient that its uptake is limited over other elements under saline conditions due to decrease in the permeability of plant roots, soil microbial activity and mineralization of organic compounds and nitrate uptake by high concentrations of chloride anions in the root zo...
using plant growth regulators at the stresses environment can improve plant growth and crop production. hence, in this research response of photosynthesis rate, chlorophyll, soluble sugar and flower dry weight of chamomile to methyl jasmonate under different salinity levels was studied. values of 0 (control), 75, 150, 225 and 300μm methyl jasmonate (meja) with salinity levels of 2, 6, 10 and 14...
In order to evaluate of lentil landrace genotypes response via germination and seedling traits to drought and salinity stress, one factorial experiment with three factors (drought, salinity and genotypes) on bias Completely Randomized Design was conducted with three replications at the laboratory of agricultural faculty of Islamic Azad University of Tabriz branch. The levels of factors were ...
This experiment was conducted in order to evaluate the effect of salinity stress on some traits of two barley genotypes (Hordeum vulgare L.) at greenhouse of Department of Agronomy and Plant Breeding, Shahrekord University, Shahrekord, Iran. A factorial experiment was carried out based on randomized complete block design (RCBD) with three replications. Treatments included two barley genotypes (...
