In order to study the effect of chitosan on growth and some biochemical characteristics of chickpea under salinity stress condition a greenhouse experiment was conducted in Vali-e-Asr University of Rafsanjan in 1392, as factorial arrangement in completely randomized design with three replications. Experimental factors included salinity (0, 4, 6 and 8 dS/m) and level of chitosan (0, 0.1, 0.2%, a...

To assess nickel-induced toxicity in plants, Zea mays seeds were germinated and cultured on nutrient solution with nickel concentrations of 0, 50, 100 and 200 μM for a period of two weeks. Its effects on the growth, Hill reaction and photosynthetic pigments content were then investigated. The fresh and dry weight of leaves and roots increased in 50 μM nickel, but decreased in 100 and 200 ...

the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...

during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...

Salinity stress is one of the major abiotic stresses which injures plants by limited water absorption and nutrient imbalance and limits crop growth. In order to study the effect of nitrogen fertilizer on physiological traits of quinoa at high salt concentrations, a greenhouse experiment was conducted in a factorial arrangement based on a randomized complete block with three replications in 2019...

The influence of endophyte fungus piriformospora indica on characteristics of the growth, water status, photosynthetic pigments concentration, gas exchange, and chlorophyll fluorescence of tomato plants under salt stress (0, 50, 100 and 150 mM) was studied in the greenhouse. Under salt stress, mycorrhizal tomato plants had higher dry weight of shoot and root, higher height, higher carotenoid an...

In order to study the effects of water deficit and foliar application of salicylic acid and spermine on dry matter production and biochemical and morphological treats of Echinacea purpurea, a split plot experiment was conducted based on randomized complete block design with three replicated during 2016- 2017 growing seasons at research field of Institute of Forests and Rangelands, Iran. In this...
