Abstract

Because of their extensive underground structures, control of perennial weeds is very difficult. In this study, factors that influence the germination and control of licorice (Glycyrrhiza glabra L.) rhizomes were studied under laboratory and nursery conditions from 2002 to 2004. Results indicated that Glycyrrhiza glabra L. rhizomes buds did not germinated below 6°c. They need at least 154 degree days before they could germinate. Rhizomes were also exposed to low temperatures (5, 0, -3, -5 and -10°c) under submerged, field capacity and dry soil in a factorial design. Results showed that rhizome buds germination decreased under submerged soil at 5°c. Under all soil moisture regimes no rhizome could survive freezing temperature of -3°c and below. In dessication experiments, no buds survived 10 days of desiccation at 25°c and higher. Totally the results of the experiments showed that the control of licorice (Glycyrrhiza glabra L.) rhizomes with physical methods is possible in laboratory conditions.
