The present study was undertaken in order to evaluate nativedesiccation tolerance and its mechanism in wheat seedlings of different genotypes. At the first step, drought stress was applied by using different concentrations of poly ethylene glycol (PEG) and mannitol. Since the fact that these compounds (even in high concentrations) were not able to produce sever water stress, the experiment was ...

Woad (Isatis cappadocica Desv.) is a herbal plant, native to central and western Asia and from Brassicaceae family. In this research, we have investigated the effects of different irrigation levels on plant morphological and physiological attributes including canopy area, roots and shoots dry and fresh weight, roots length, proline concentration, shoots soluble carbohydrates content and antioxi...

abstract this study examines the relationship between reading anxiety and difficulty of texts as well as the relationship between reading anxiety and students perceived difficulty of the texts. since difficulty is a relative concept, i limited its definition by sticking to the readability formula. we also took students perceived difficulty levels into account. therefore, in the present study, ...

some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...

This experiment was conducted to evaluate drought tolerance of selected lines from local populations of safflower (Carthamus tinctorius L.) at the Research Farm of Isfahan University of Technology in 2002. In this study, the 12 selected safflower lines from different local populations along with two exotic cultivars and a local population were evaluated at two different irrigation regimes, usin...

In order to investigate the effect of water deficit on yield and morphological characteristics of four alfalfa cultivars an experiment was conducted as a split plot in randomized complete block design with 3 replications in Agriculture Research Center of Khuzestan, Ahwaz, Iran, during 201l-2012. Main plots included irrigation regimes (normal irrigation, irrigation at 50% available water content...
