    Notes: Summary Alkaloids washed from the seeds ofDatura stramonium inhibited the early gowth ofHelianthus annuus in Black Earth and Lateritic Podzolic soils. Under laboratory conditions, the magnitude of the inhibition was greater in the Lateritic Podzolic than the Black Earth soil. Phytotoxicity ofD. stramonium alkaloids persisted for 20 weeks in Lateritic Podzolic soil under controlled conditions, and for eight months in aD. stramonium-infested Black Earth soil in the field.

    Primary effects of allelochemicals ofDatura stramonium L. (1987)
    Springer
    Plant and soil 98 (1987), S. 137-144 
    Details
    ISSN: 1573-5036

    Notes: Summary Alkaloids leached from seed ofDatura stramonium were identified as scopolamine and hyoscyamine and levels leached from seed over a seven day period were quantified. Scopolamine is known to inhibit early seedling growth of some crop plants. The hypothesis that such inhibition results from interference with gibberellin-stimulated food reserve metabolism in germinating seedlings was tested, using barley and wheat in bioassays. Seedling growth of both cereals was inhibited by scopolamine but no evidence of interference with responses to gibberellins was obtained.
