    Effects of species of VA-mycorrhizal fungi on growth and mineral uptake of sorghum at different temperatures (1990)
    Springer
    Plant and soil 121 (1990), S. 165-170 
    Details
    ISSN: 1573-5036
    Schlagwort(e): Glomus fasciculatum ; Glomus intraradices ; Glomus macrocarpum ; mineral nutrition ; soil temperature ; Sorghum bicolor ; uptake of P, K, S, Fe, and Zn ; VAMF ; vesicular-arbuscular mycorrhizal fungi

    Notizen: Abstract Sorghum [Sorghum bicolor (L.) Moench] plants were grown in growth chambers at 20, 25 and 30°C in a low P Typic Argiudoll (3.65 µg P g−1 soil, pH 8.3) inoculated with Glomus fasciculatum, Glomus intraradices, and Glomus macrocarpum to determine effects of vesicular-arbuscular mycorrhizal fungi (VAMF) species on plant growth and mineral nutrient uptake. Sorghum root colonization by VAMF and plant responses to Glomus species were temperature dependent. G. macrocarpum colonized sorghum roots best and enhanced plant growth and mineral uptake considerably more than the other VAMF species, especially at 30°C. G. fasciculatum enhanced shoot growth at 20 and 25°C, and mineral uptake only at 20°C. G. intraradices depressed shoot growth and mineral uptake at 30°C. G. macrocarpum enhanced shoot P, K, and Zn at all temperatures, and Fe at 25 and 30°C above that which could be accounted for by increased biomass. Sorghum plant growth responses to colonization by VAMF species may need to be evaluated at different temperatures to optimize beneficial effects.

    Hydrocarbon accumulation in freshwater sediments of an urban catchment (1982)
    Springer
    Hydrobiologia 91-92 (1982), S. 285-292 
    Details
    ISSN: 1573-5117
    Schlagwort(e): PAH ; aliphatic hydrocarbons ; sediment ; stormwater
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Abstract The top and bottom of two sediment cores collected from an urban receiving basin in NW London, and stormwater samples from the attendant catchment, have been analysed for their hydrocarbon content. In surface sediments, basal sediments and stormwater, total aliphatic hydrocarbon levels are 445–690 µg g−1 dry wt., 43–224 µg g−1 and 0.36–1.10 mg l−1, respectively; and total levels of polyaromatic hydrocarbons (PAHs) are 780–1 100 µg g−1, 310–640 µg g1 and 5.83–18.21 mg l−1, respectively. Biodegradation of aliphatics is assessed by phytane:n-C18 and pristane: n-C17 ratios. Hydrocarbon sources are determined from phytane: pristane ratios, odd: even carbon chain length ratios, the presence of an unresolved complex mixture, and by comparison of the amount of methyl-substituted PAH s with that of the parent compounds. Comparison of total levels between surface and basal sediments shows a 1 to 3 fold increase in total PAHs and a 3 to 10 fold increase in aliphatic hydrocarbons over a 120 year period.
