density of rhizobium population in faba bean (vicia faba l.) fields of wollo area (asketema, gashana, kotem, major and sekota) northern ethiopia was studied. the highest population of rhizobia was found at major and the least at sekota regions. the native rhizobial strains isolated from the northern parts of the country tolerated a higher salt concentration (5% nacl) than the exotic rhizobial s...

hybrid populations (f3) derived from cross between four moderate salt-resistant spring wheat (triticum aestivum l.) were assessed for transgressive segregation of salt-tolerant genotypes allowing germination and emergence at 350 mm nacl for 30 days. the achieved selection intensity was the order of 0.24-0.27 in these segregation populations (22-25 seedlings from 9000 seeds). assessment of trans...

Salt stress is one of the major constraints for wheat cultivation inIranand leads to a considerable loss in crop yield each year. In high salinity soils, the reduced osmotic potential of soil solutes may cause physiological drought. In this study the salt tolerance of different drought-tolerant bread wheat genotypes were studied by examining various agronomic and physiological traits, inclu...

although inter-variety variability for salt tolerance has been reported in bread wheat plants, little information is available on the genetic control of ion contents and biomass yield under saline conditions. a diallel cross, including reciprocals of two salt tolerant, two moderately tolerant and two sensitive iranian and exotic bread wheat varieties, was analyzed to investigate the inheritance...

Synthesis of the first P(V)-bridged bis(NHC) ligand 7 was achieved via deprotonation of P(V)-functionalized bis(imidazolium) salt 6, which was obtained via oxidative desulfurization of bis(imidazole-2-thion-4-yl)phosphane 2. Bis(imidazolium) salt 6 was also employed to synthesize the corresponding silver complex 8. All new products were firmly established by spectroscopic and spectrometric meth...

A chemical-responsive bis(m-phenylene)-32-crown-10/2,7-diazapyrenium salt [2]pseudorotaxane was prepared. It was found to form a supramolecular poly[2]pseudorotaxane in the solid state driven by π-π stacking interactions.
