title: Strigol Analogs Inhibit Seedling Growth and Haustorial Development in Sopubia delphinifolia G. Don. -A Hemi-root Parasite.
abstract: The effects of synthetic strigol analogs, GR-7, GR-24, and GR-28, were studied on seed germination, seedling growth and haustorial development in a tropical hemi-root parasite, Sopubia delphinifolia. All the three GR-compounds significantly stimulated seed germination but inhibited seedling growth, particularly the root growth. They also inhibited gum tragacanth-induced haustorial development. It is discussed that GR-compounds may not only induce «suicidal germination» but also exert post-germination control, even in the presence of host plants.
