Modeling plant response to salinity and nitrogen deficiency is very important for estimating optimum yield in arid and semi-arid regions. For this purpose, the models of Leibig-Sprengel (LS) and Mitscherlich-Baule (MB) originally proposed to explain plant response to nutrients only were modified to evaluate plant yield response to combined nitrogen and salinity stress conditions. Afterwards, in...
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...
Freshwater pulses (during which river discharge is much higher than average) occur in many estuaries and strongly impact estuarine functioning. To gain insight into the salinity response to freshwater pulses, an idealized model presented. With respect earlier models on spatiotemporal behavior of estuaries, it includes additional processes that provide a more detailed vertical structure salinity...
Salinity is one of the most important problems that restrict cultivation of crops in arid and semi-arid regions. Pistachio (Pistacia vera L.) is one of the most important trees that grow in these restricts. In this greenhouse study, the effects of salinity on growth of pistachio rootstock Badami evaluated. Seedlings were grown in plastic bags containing perlite. Salinity was imposed, by adding ...
reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
plant response to salinity varies at different growth stages. information on plant response to salinity at various growth stages can be used in managing saline waters for irrigation. in order to measure the quantitative response of salinity on germination of sorghum (sorghum bicolor l. moench), a greenhouse experiment was conducted in a natural saline sandy loam soil, using plastic pots with 15...
Extended Abstract Introduction and Objective: Considering the importance of salinity in wheat and the multigene nature of this trait, the present study was conducted to investigate the expression of key genes involved in the response of wheat to this stress and to create their network. Material and Methods: In this study, the expression of key genes (HKT, DREB, bZIP, NAC, and WARKY) involved...
Transcription factors of the AP2/ERF family play important roles in plant growth, development, and responses to biotic and abiotic stresses. In this study, a physic nut AP2/ERF gene, JcDREB2, was functionally characterized. Real-time PCR analysis revealed that JcDREB2 was expressed mainly in the leaf and could be induced by abscisic acid but suppressed by gibberellin (GA) and salt. Transient ex...
to investigate the effects of different salinity levels of nacl on germination of safflower (cv. esfahan 24) seeds under three different incubation methods, a factorial experiment was carried out based on a complete randomize design with three replications. salinity levels were 0, 5, 10, 15 and 20 dsm-1 (nacl) and incubation methods were sandwich method, and using petri dishes with open or clos...
this research was carried on to evaluate the response of rapeseed varieties to salt stress. in this experiment growth response of three rapeseed varieties (fornex, consoul and okamer) in four salinity levels (0, 40, 80 and 120 mmol nacl) was investigated using a factorial arrangement of factors in a complete randomized block design with three replications. results incicated that in the highest ...
