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...

Sericulture has played a very important role in the socio-economic empowerment of rural and semi-urban population. The eco-friendly nature of the industry, in addition to its employment generation potential, low investments and frequent returns, has rendered the industry as one of the most suitable land based economic activity, particularly in the context of global movement against environmenta...

Background & Objective: Stress contributes to sleep-wake behavior in all animals. It seems that factors such as learning and memory processes can improve sleep disorders. Therefore, the present study was conducted to determine the effects of stress and learning (spatial memory) on total post-stress rapid-eye-movement (REM), non-rapid-eye-movement (NREM) and waking time in rats. Materials & Met...

The possible alleviating effects of salicylic acid on protection of cowpea (Vigna unguiculata) cv. Parastu under water stress conditions were investigated in the University of Zanjan Agriculture Research Station during 2008. Water stress was imposed by withholding irrigation at 50% flowering (flowering water stress, FWS) and when 50% of the pods grew 2-3cm (pod-formation water stress, PFWS). Sa...

heat stress is well recognized among the hazardous physical agents that might be present during work. this study aims to compare wbgt index at acclimated and unacclimated people to permissible threshold limit value and study the differences between physiological parameters at them. twenty one healthy men were participated in the study. all of the subjects were monitored in two different weather...

in order to investigate the effects of salicylic acid on some growth and stomatal characteristics of calendula plant, a factorial experiment was conducted based on completely randomized design with five replications in the research greenhouse of shahid bahonar university of kerman in 2013. salt stress levels including 1, 3, 5, 7 and 9 mmhos/cm were applied to the soil and salicylic acid solutio...

drought and salinity are the most important limiting factors of plant growth and development in many regions of the world. in this regard, using of species that are able to have higher production in this condition is a suitable strategy. in order to study the effect of drought and salinity stresses on morphophysiological properties of kallar grass (leptochloa fusca l. kunth), a factorial experi...
