Considering the increasing trend of saline land enhancement and lack of appropriate agricultural lands, identifying salt resistant plants such as fenugreek, which is an important medicinal plant, is important. To do so, a factorial experiment was conducted in the form of randomized complete blocks design with three replications on three fenugreek landraces (Yazd, Shiraz and Hendi) and five sali...
salinity is one of the environmental factors that have a critical influence on the plant emergence and plant growth and establishment. the determination of salinity tolerance threshold is a useful criterion to choose soil and irrigation water for cultivation of halophytes. in order to determine salinity tolerance threshold in amaranthus retrofelexus, an experiment was performed in greenhouse ba...
In order to evaluate the salinity tolerance of oat genotypes (Avena sativa L.), at seedling and reproductive stages, an experiment with three replications was carried out in greenhouse condition (based on Randomized Completely Design). Experiments were carried out in research field of Esfahan University of Technology. which is located in Lourk’s Najafabad without stress, EC=4 ds/m, as well as ...
abstract salinity tolerance is one of the major factor influencing crop productivity in arid and semi-arid areas. the salinity tolerance of fruit trees can be enhanced through the use of tolerant rootstocks. this experiment was conducted to investigate the effects of salinity stress and rootstock on the growth, photosynthetic rate and nutrient concentrations of almond (prunus dulcis miller.) cv...
determination of chlorophyll content and chlorophyll fluorescence has the potential needed to analyze the efficiency of photosynthesis in plants against environmental stresses, especially salinity, and its simplicity facilitates stress evaluation. in order to study the response of different photosynthetic characters to salinity stress at different sugar beet growth stages, two separate experime...
Salinity-affected and heavy metal-contaminated soils limit the growth of glycophytic plants. Identifying genes responsible for superior tolerance to salinity and heavy metals in halophytes has great potential for use in developing salinity- and Cd-tolerant glycophytes. The objective of this study was to identify salinity- and Cd-tolerance related genes in seashore paspalum (Paspalum vaginatum),...
Most researches on wheat and barley breeding for salt tolerance have focused mainly on excluding Na+ from different tissues but the results of some experiments suggest that contribution of Na+ exclusion to salt tolerance is overshadowed by other physiological responses. Three bread wheat cultivars differing in salt tolerance (Arg, Tajan and Baharan) and one barley cultivar (Nik) were employed t...
in order to evaluate salinity tolerance in 20 sugar bee genotypes, an experiment was conducted in two fields with salinity (ec= 12 ds/m, ph= 7.6) and non-salinity stress, in the form of rcbd at miandoab agricultural research station. different morphological and physiological traits such as root yield, sugar percentage, white sugar percentage, molasses, n, na, k, syrup purity and green cover per...
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...
Increasing the yield of wheat (Triticum aestivum) requires choosing resistant and compatible cultivars to different climatic conditions. In order to study the effects of salinity and drought stress on grain yield, Study of stress tolerance indices and identification of tolerant genotypes to salt and drought stress, 20 different Wheat (Triticum aestivum) genotypes were assessed in a Randomized ...
