    Notes: Summary We studied the effects of field application rates of three fungicides on spore germination and root infection in three species of Glomus. Bavistin (carbendazim) prevented germination of spores of G. monosporum and G. mosseae whereas Calixin (tridemorph) had no effect. Tilt Turbo (propiconazole) inhibited spore germination less than Bavistin. Spores of G. geosporum germinated in the presence of all three fungicides. Foliar applications of Bavistin alone and in a triple-spray programme significantly reduced infection of all three Glomus species in wheat roots grown in conditions of low P availability (2 mg P 1−1). Two fungicides with triazole derivatives, Sportak and Tilt Turbo, also decreased infection and the former significantly reduced spore production of all three Glomus species. Calixin-treated plants, however, showed increased infection levels, resulting in greater yields and greater foliar-P concentrations than control plants. Milgo (ethirimol) was not detrimental to the vesicular-arbuscular mycorrhizal (VAM) symbiosis when applied as a foliar spray.

    Sulfur accumulation in western wheatgrass exposed to three controlled SO2 concentrations (1979)
    Springer
    Plant and soil 53 (1979), S. 131-136 
    Details
    ISSN: 1573-5036

    Notes: Summary Sulfur concentrations of western wheatgrass tillers and individual leaves were measured from plants exposed to four SO2 concentrations (9, 52, 105 and 183 μg·m−3). Sulfur concentration of plants was a linear function of either time of exposure or concentration. Young leaves and the youngest portion of leaves contained less sulfur than their older counterparts irregardless of whether they had or had not been exposed to SO2. Current hypotheses which relate plant sensitivity to amount of sulfur taken up do not apply for western wheatgrass.

    Distribution of monoamines in the diencephalon and pituitary of the dogfish, Scyliorhinus canicula L. (1973)

    Notes: Summary The distribution of monoamines in the diencephalon and pituitary of the dogfish, Scyliorhinus canicula, has been investigated using the histochemical fluorescence technique of Falck and Hillarp (Falck and Owman, 1965). Terminals of monoamine-containing axons were found in the neurointermediate lobe of the pituitary and the axons were traced, by means of nialamide and L-dopa treatment and lesions, to the nucleus medius hypothalamicus. A separate hypothalamic system converging on the anterior median eminence and the occurrence of aminergic cells in the nuclei lobi inferiores and nucleus medius hypothalamicus were similarly demonstrated. Normal fish show a bilateral uncrossed tegmental tract and two areas of catecholamine-containing neurones in modified ependymal organs. The organum vasculosum hypothalami includes both primary catecholamine and 5-hydroxytryptamine-containing cell types whilst the organum vasculosum praeopticum has only the former type. Both organs contain cells which send club-like processes into the third ventricle. The subcommissural organ does not contain monoamines. The role of hypothalamic catecholamine systems in the regulation of pituitary function is discussed.
