The paper describes method for situations assessment based on retrieving information about similar earlier observed conditions. Situation is a set of qualitative and quantitative characteristics that describe states of interrelated objects. Object states are defined by measurement parameters. A method for situation assessment is based on calculation of aggregated indices and their comparison wa...

salinity and sodicity are the major factors of soil degradation in arid and semiarid areas. the main aim of this study was to evaluate the capability of liss_iii data for soil salinity and sodicity mapping in a selected part of the qazvin plain, an area of arid environment. during the study, spectral classes were carried out of the remotely sensed data and then with the help of field observatio...

Saplings of Eucalyptus camaldulensis Dehn. Clone 4544, irrigated with water of differing salinities (2 to 28 dS m-1) and boron concentrations (1 to 30 mg l-1), integrated the history of these stresses through the discrimination of stable isotopes of carbon in leaf and woody tissues. Carbon isotope discrimination (delta) was reduced primarily by salinity. Decreases in discrimination in response ...

Salinity tolerance in rice is highly desirable to sustain production in areas rendered saline due to various reasons. It is a complex quantitative trait having different components, which can be dissected effectively by genome-wide association study (GWAS). Here, we implemented GWAS to identify loci controlling salinity tolerance in rice. A custom-designed array based on 6,000 single nucleotide...

This study investigated sucrose metabolism of the youngest fully expanded main-stem leaf (MSL) and the subtending leaf of cotton (Gossypium hirsutum L.) boll (LSCB) of salt-tolerant (CCRI-79) and salt-sensitive (Simian 3) cultivars and its relationship to boll weight under low, medium and high soil salinity stress in Dafeng, China, in 2013 and 2014. The results showed that with increased soil s...

Effect of Nanoparticles and Biofertilizers on Chlorophyll Fluorescence Indices Some Physiological Traits Triticale (Triticosecale Wittmack) under Salinity Stress

background and objectives: the region of the experiment is located in golestan province, iran, with agriculture subject to various farming conditions (rain-fed and irrigation) and different levels of salinity (more than 38% of golestan’s total land area is salt-affected). the purpose of this study has been to evaluate the stress indices in the selection of tolerant wheat genotypes, not only for...
