Arsenic (As) stress, through the creation of oxidative stress, can cause phytotoxicity (e.g. The decrease of growth and chlorophyll content) in plants. Nitric oxide (NO), by promotion of the antioxidant system, plays an important role in reducing heavy metal-induced oxidative stress. In this study, the role of exogenously applied sodium nitroprusside (SNP; a NO donor) on physiological responses...
In order to evaluate morphological and physiological responses of sorghum (Pegah cultivar) to salt stress (0, 5, 10 and 15 dS/m) and different salicylic acid (SA) levels (0, 0.75 and 1.5 mM), an experiment was carried out in research green house of college of Agriculture Shiraz University during 2012 using a factorial as randomized complete block design with four replications. The results ...
six hundred 1-d-old male broilers (ross 308) were assigned to four experimental groups; each was composed of 5 floor pen replications of 30 birds including control (no enalapril), 15, 30 and 60 ppm enalapril in the drinking water. from d 21 to 49, all the chicks were exposed to low ambient temperature to induce ascites. mortalities were inspected to determine the cause of death and diagnose of ...
In natural environment and agricultural conditions, plants are frequently exposed to environmental stresses. One of the main factors reducing the worlds agricultural production is drought. In this research the effect of drought stress on physiological parameters of some cultivars of sorghum was studied in vitro. The seeds of sorghum were sterilized and then were cultured in MS medium supplement...
decrease of cell defense mechanisms efficiency and oxidative stress accruing in lake of mg condition
a hydroponic experiment was conducted to investigate the effect of of magnesium (mg) deficiency on plant cell metabolism in pgs durum wheat cultivar. the experiment was conducted in 4 replications as a completely randomized design in 2010. result showed that magnesium deficiency increased reactive oxygen species (ros) production such as hydrogen peroxide (h2o2). furthermore, mg deficiency decli...
Redroot pigweed (Amaranthus retroflexus L.) is a noxious and cosmopolitan weed that is widely distributed in different parts of the world and competes severely with crops and reduces their growth and yield. The present study was conducted to investigate the effect of drought stress on some morphological and physiological characteristics of redroot pigweed in 2018 and 2019. Treatments included d...
In order to study the effect of salicylic acid and selenium foliar application on physiological characteristics, yield and yield components of safflower (Carthamus tictorius L.) under drought stress conditions, an experiment was conducted as split plot based on randomized complete block design with three replications. The main factor included irrigation in three levels, complete irrigation duri...
Six hundred 1-d-old male broilers (Ross 308) were assigned to four experimental groups; each was composed of 5 floor pen replications of 30 birds including control (no enalapril), 15, 30 and 60 ppm enalapril in the drinking water. From d 21 to 49, all the chicks were exposed to low ambient temperature to induce ascites. Mortalities were inspected to determine the cause of death and diagnose of ...
In order to investigate the effect of salinity and cadmium (Cd) on yield, chlorophyll content and antioxidant activity of Kochia plant, a factorial experiment in a completely randomized design with three replications was conducted under greenhouse conditions. The experimental treatments included five Cd levels (0, 5, 30, 60 and 90 mg Cd kg-1 soil as cadmium sulphate) and three salinity levels (...
