Abstract

In order to investigate the allelophatic effects of shoot and root aqueous extract of licorice (Glycyrrhiza glabra L.) and pigweed (Amaranthus retroflexus L.) on seed germination and seedling characteristic of Corn (Zea maize L.) and Chickpea(Cicer arietinum L .), a research was conducted based on completely randomized design with four replications, in research laboratory of faculty of agriculture, University of Kerman, Iran in 2010. Treatments were four levels (25, 50, 75 and 100%) of leaf, stem, flower and root water extracts weeds (Glycyrrhiza glabra L.) and (Amaranthus retroflexus L.) with distilled water as control. Results showed that there were allelopathic effects in Velvet flower and Glycyrrhizin, effect of aqueous extract of different plant parts on germination traits of maize and chickpea was not similar. Increasing the aqueous extract concentrations of separated Velvet flower and Glycyrrhizin plant parts significantly inhibited maize and chickpea percentage and rate of germination, length of radical and hypocotyls and increased time to 10 and 90% of germination. The degree of allelopathic effects of different Velvet flower and Glycyrrhizin plant parts can be classified in order of decreasing inhibition as follows: stem, leaf, flower and root, and between two medicinal plants, Glycyrrhizin indicated more allelopathic effects on germination traits.
