salinity is one of the most important widespread abiotic stresses which causes toxic and nutritional effects as well as loss of water absorption ability by plants. plants respond to salinity with morphological changes. due to high susceptibility of chickpea to salt stress, some physiological and morphological responses occur following the stress in this plant. thus, different concentrations of ...

this study was carried out in order to evaluate allelic diversity of microsatellite markers in qtl region for salinity tolerance on chromosome 10 in rice and evaluation of agronomical traits of some iranian rice cultivars in salinity stress along with two tolerant (pokkali) and sensitive (ir29) check varieties, and association analysis for morphological traits using microsatellite markers.based...

The main objective of this research was to evaluate fifteen durum wheat (Triticum durum) genotypes selected from joint project of Iran/ICARDA for drought tolerance using several indices. The trials were conducted under moderate levels of drought stress for three cropping seasons (2004-2006) in four locations in the highlands western of Iran. The combined ANOVA for grain yield over years and loc...

the present study carried out an in vitro experiment on effects of salinity and temperature on acartia tonsa life cycle from caspian sea. during the experiment, temperature and salinity ranged 25, 27, 29 ± 1 °c and 12‰ and 17‰, respectively within a period of 60 days. spawning rate was measured using mesh size of 100 µ planktonic net from surface to 10 m depth. early results show that nauplii a...

Susceptibility and vulnerability to impacts make Cetaceans Benthic Foraminifera sentinels of health in marine environments. A breeding population Right whales (Eubalaena australis) annually migrates the “Environmental Protection Area” Santa Catarina, Brazil, where Ribanceira/Ibiraquera Bay, its harbor, are located. Since rest shallow areas, their stomachs touch sediment bottom, foraminiferal as...

as compared to ksc 704 hybrid with 9.844 t/ha, the maize hybrid, ksc 705(k3640/3 × mo17) produced an average grain yield of 11.120 t/ha over seven locations evaluated in final trials for two consecutive years (2007-8). in advanced yield trials done in 2011, across seven locations, this hybrid performed the highest grain yield, 10.450 t/ha, while ksc 704 produced 8.513 t/ha. in addition to the g...

Engineering of salinity tolerance in agronomically important crop plants is required to increase their productivity by enabling them to grow in saline soils, which are otherwise left uncultivated. Since an increase in the enzymes of glyoxalase system has been shown to impart salinity tolerance in the model plant tobacco, we used the glyoxalase II gene for engineering salinity tolerance in an im...

in order to develop a high yielding rice cultivar with optimum cooking quality, a cross was conducted between two rice cultivars khazar, high yielding and resistant to blast disease and daylamani tarom, with good cooking quality in 1990. forty pure lines were selected and compared for high grain yield in 1996. ten selected lines together with two check cultivars dasht and onda were tested in ad...
