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...

Response features of taste receptor cell action potentials were examined using an artificial neural network to determine whether they contain information about taste quality. Using the loose patch technique to record from hamster taste buds in vivo we recorded population responses of single fungiform papillae to NaCl (100 mM), sucrose (200 mM) and the synthetic sweetener NC-00274-01 (NC-01) (20...

Phase-partitioning studies of the euryhaline bacterium Halomonas elongata demonstrated that the hydrophobic-hydrophilic nature of the cell surface changed as the bacterium grew in different NaCl concentrations. Mid-log-phase cells grown in a high (3.4 M) NaCl concentration were more hydrophilic than were cells grown in a low (0.05 M) NaCl concentration. Mid-log-phase cells from defined medium c...

The palatability and taste quality of pyrophosphates were evaluated in a series of behavioral and electrophysiological experiments. In two-bottle choice tests with water, rats strongly preferred some concentrations of Na3HP2O7 and Na4P2O7, moderately preferred some concentrations of K4P2O7 and Fe4(P2O7)3, and were indifferent to or avoided all concentrations of Ca2P2O7 and Na2H2P2O7. The contri...

plant tissue culture techniques were used to study the effect of nacl on tropane alkaloids accumulation and proline content of both datura metel and datura stramonium. callus cultures were established for both datura species. however, ms medium supplemented with 1mg/l of both ba and naa was the best for callus production in d. metel, while ms supplemented with 3 mg/l kin and 1 mg/l 2, 4-d was t...
