A major problem of arid and semi-arid regions is environmental stresses like salinity and drought. To study the effect of Artichoke germination under different levels of salinity and drought, two separate experiments were performed. The experimental treatments included different salinity levels of NaCl (0, 50, 100, 150 mM) and five drought levels by PEG (0, 10%, 15%, 20% and 25%) with three rep...

The bicistronic groESL operon, encoding the Hsp60 and Hsp10 chaperonins, was cloned into an integrative expression vector, pFPN, and incorporated at an innocuous site in the Anabaena sp. strain PCC7120 genome. In the recombinant Anabaena strain, the additional groESL operon was expressed from a strong cyanobacterial P(psbA1) promoter without hampering the stress-responsive expression of the nat...

abstract plants are exposed to stressful environmental conditions in the process of growth and development. one of the most important stresses is the salt stress which can limit the plant’s growth and yield. plants symbiosis with arbuscular mycorrhizal fungi in salt conditions can affect the plant’s yield as well as growth parameters. the plant’s growth in salt stressful conditions might be red...

World population is increasing at an alarming rate and is expected to reach about six billion by the end of year 2050. On the other hand food productivity is decreasing due to the effect of various abiotic stresses; therefore minimizing these losses is a major area of concern for all nations to cope with the increasing food requirements. Cold, salinity and drought are among the major stresses, ...

This experiment was conducted to determine the effect of salinity and nitrogen on growth and yield of tomato and concentration and total uptake of some nutrients in different parts of plant in hydroponics culture. Nitrogen (N) was used at 0, 1.5 and 3% levels as NH4Cl and NH4H2PO4 and salinity consisted of 0, 30 and 60 mM as NaCl and CaCl2 (2:1 w/w). A completely randomized design experiment wa...

Objective: Germination is one of the most important stages of plants growth that affected by environmental stresses, especially drought and salinity. Methods: In order to study of Artichoke germination under different levels of salinity and drought, two separate experiments were performed. The four levels of salinity by NaCl (0, 50, 100, 150 mM) with three replications and five levels of drough...

The current study aimed to investigate the effect of two abiotic stresses including salinity and drought on seed germination characteristics of Allyssum hamalocarpum in vitro. The experiment was designed as factorial completely randomized with four replications. Treatment included five levels of drought i.e. 0, – 0.19, – 0.25, – 0.41 and – 0.99 Mpa and five levels of salinity including 0, 50, 1...

many phragmites-dominated wetlands have been markedly salinized and alkalinized in the songnen plain, northeastern china. agricultural wastewater with high nitrogen content has been discharged into these alkalinized-salinized wetlands. to understand the effect of salinity-alkalinity on reed (phragmites australis) seedlings at various nitrogen levels, we examined photosynthesis rate, chlorophyll...
