Abstract:
In this study, mostly weeds, the effect of 22 plant`s extracts on germination of seeds from nine different weeds was investigated. Plants used were sampled with their leaves and flowers, in 2002, then plant extracts were obtained after they were ground and processed with methanol. The experiments were conducted in 9 cm diameter sterile petri dishes inside covered with sterile filter paper. Fifty seeds were placed in each of petri dishes. Acetone (10%) was used as the control. The seeds germinated were taken out from the petri dishes and counted in every three days during 21 days. Lepidium sativum L. was very slightly affected by the extracts. All the weed extracts except Lolium temulentum L. were stimulated the seed germination of Descurania sophia L. Webb. Ex. Prant. at a different levels. Germination of Lolium perenne L. were inhibited most strongly by Salvia officinalis L., Laurus nobilus L. and Artemisia vulgaris L. The extracts of all the plants studied inhibited the germination of Abutilon theophrastii Medik, Amaranthus retroflexus L., Avena sterilis L., Rumex crispus L., and Trifolium repens L. It was concluded that some of these extracts may be used as herbicide to control the germination and growth of some other weeds.
