    Notizen: Abstract The limiting conductance of various salts of Na+, Ag+, Cu+, Cu2+ and Ph4As+ in acetonitrile-water (AN-H2O) and pyridine-water (Py−H2O) mixtures are reported. Single ion values are calculated for AN-H2O mixtures using the TATB assumption [λo(Ph 4 As +) = λo(Ph 4 B −)]. The trends observed for the limiting Walden products (λoη) of the electrolytes and individual ions are discussed in terms of specific ion-solvent interactions and the structural effects of the solvent mixtures.

    Epistatic, additive and dominance variation in a triple test cross of bread wheat (Triticum aestivum L.) (1982)

    Notizen: Summary Triple test cross progenies resulting from the crossing of three testers (‘Kloka’, ‘UP 368’ and an f1 intermediate between them) and 24 varieties of bread wheat have been studied for plant height (cm), peduncle length (cm), ear length (cm), number of spikelets per spike and harvest index (ratio between economic and total yield). Epistasis was not significant for any of the characters studied. The testers were inadequate for plant height and for peduncle length although the testers varied considerably for these traits. Additive variance played a significant role in the inheritance of all the characters except number of spikelets per spike. The dominance variance was important for plant height, ear length and harvest index. The degree of dominance was in the over-dominance range for plant height. Complete dominance was operative for ear length, number of spikelets per spike and harvest index whereas for peduncle length only partial dominance was observed. The possibility of the isolation of the recombinants with high harvest index has been stressed.
