    Notizen: Summary We studied the effects of field application rates of four herbicides (Avenge, Ceridor, Dicurane, and Harrier) on spore germination and infection of wheat roots by three species of Glomus grown under conditions of low P availability. Low concentrations of Ceridor (bifenox, mecoprop) and Harrier (mecoprop, ioxynil, clopyralid) inhibited spore germination while higher concentrations were stimulatory. Avenge (difenzoquat methyl sulphate) prevented spore germination completely, while Dicurane (chlortoluron) had no effect. The herbicide applications had no significant effect on the infection rates of any of the three fungi except Harrier on G. geosporum. The herbicide treatments did, however, affect plant growth and ear yields. Ceridor and Harrier increased ear yields, while Dicurane showed marked phytotoxic effects.

    Effect of fungicides on three vesicular-arbuscular mycorrhizal fungi associated with winter wheat (Triticum aestivum L.) (1989)

    Notizen: 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.

    The interaction of atmospheric and soil sulfur on the sulfur and selenium concentration of range plants (1983)
    Springer
    Plant and soil 72 (1983), S. 117-125 
    Details
    ISSN: 1573-5036
    Schlagwort(e): Atmosphere ; Selenium ; Sulfur ; Sulfur dioxide

    Notizen: Summary A native northern mixed prairie, Montana, U.S.A., was exposed to three controlled levels of sulfur dioxide and subplots fertilized with sulfur and/or selenium. Plant species that accumulated relatively greater quantities of soil sulfur did not necessarily accumulate relatively greater quantities of atmospheric sulfur, andvisa versa. Plant-sulfur concentrations increased with increasing time and level of exposure, but the rate of increase in plant-sulfur concentrations decreased with increasing SO2 concentration. Plants exposed to the high-SO2 concentration tended to have lower sulfur concentrations when growing in the sulfur-or the selenium-fertilized plots. High soil selenium caused a reduction in plant-sulfur content, but a decrease in plant selenium concentration with high soil sulfur could be detected only when comparing plants on the selenium and sulfur plus selenium plots, where high plant selenium concentrations were encountered.

    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
    Schlagwort(e): Air pollution ; Grassland ; Native grass ; Sulfur ; Sulfur dioxide ; Uptake

    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft
    Notizen: 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.
