A pot experiment was carried out to determine the effect of foliage spraying of silicon (Si) on growth and ornamental characteristics of calendula grown under salt stress and greenhouse conditions. A factorial experiment based on completely randomized design was conducted with 3 levels of Si (0, 50 and 100 mg/l) and 3 levels of NaCl (0, 100 and 200 mM) with 4 replications. At flowering stage, S...

Castor is normally cultivated in marginal lands, in arid and semiarid climates in which its oil is commonly used in industry and medicine. For investigation of physiological responses in different castor ecotypes under different water deficit conditions, the field experiment was conducted in two locations of Isfahan and Shahrekord in year 2013. The experiment was carried out in split plot arran...
abstract the balvard metamorphic assemblage (bma) crops out at the northeastern margin of the southeastern part of the sanandaj-sirjan zone (ssz) in contacting to the dehshir-baft ophiolitic mélange. this location prepared a special situation to resolve some of the complicated tectonic problems of this part of iran. petrology, micro-tectonics and satellite image investigation were carried out ...

in order to investigate the responses of sardari wheat ecotypes to drought stress, 12 spikes of sardari wheat were selected from different regions of kurdistan province and planted as head to row. in the second year, a split- plot factorial field experiment was conducted. in this experiment water stress and irrigation were considered as the levels of main factor and 12 sardari wheat ecotypes al...
jasmonate is new plant growth regulator that plays an essential role at increasing plants resistance to the environmental stresses like salinity stress. hence, in this research the effect of foliar application of methyl jasmonate on some physiological indices and yield of german chamomile under salinity conditions was studied. a factorial experiment was laid out based on randomized complete blo...
introduction nowadays, salinity is one of the limiting factors for crop production in arid and semi-arid regions. on the other hand, sorghum (sorghum bicolor l.) is a self-pollinated and short-day plant, which partly has been adapted to salinity and water stress conditions; also play an important role in humans, livestock and poultry nourishments. all studies have showed the positive effects of...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
