    Platte Valley Yellows, a chlorotic condition of soybeans: Symptoms and preliminary chemical analyses (1982)
    Springer
    Plant and soil 68 (1982), S. 283-287 
    Details
    ISSN: 1573-5036
    Keywords: Glycine max ; Iron deficiency ; Mycorrhizae ; Nodulation ; Platte ; Valley ; Yellows ; Rhizobium ; Soybeans

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary A chlorotic condition of soybeans in the river valleys of eastern Nebraska was studied. The pattern of chlorosis, presence of petiolar necrosis, reductions in rhizobial and mycorrhizal infection, and plant and soil chemical analyses suggest that the condition is more complex than normal iron deficiency chlorosis or other mineral deficiencies or toxicities. Nodulation is almost totally inhibited in affected plants. Mycorrhizal fungi, while able to infect early in the season, do not persist on affected plants. Breakdown of endodermis was observed in the roots of affected plants. The factors contributing to this condition have not yet been determined.

    HPLC separation and wavelength area ratios of more than 50 phenolic acids and flavonoids (1985)
    Springer
    Journal of chemical ecology 11 (1985), S. 383-395 
    Details
    ISSN: 1573-1561
    Keywords: HPLC ; retention time ; area ratio ; phenolic acids ; flavonoids ; soybean ; Glycine max
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Relative retention times and wavelength area ratios for over 50 standard compounds were calculated using reverse-phase HPLC. The standard compounds analyzed included benzoic acids, cinnamic acids, benzene carboxylic acids, acetic acids, coumarins, benzaldehydes and a variety of flavonoid compounds including flavanones, flavones, isoflavones, and their glycosides. Each standard compound was chromatographed by three different gradient elutions. Compounds were detected by UV absorption at 254 nm and 280 nm. Relative retention times with respect to two different internal references and the 254nm: 280nm wavelength area ratio was determined for each standard. Soybean root and seed extracts were analyzed for the presence of the standard compounds using the chromatographic conditions described.
