Allelopathic effects of Syrian bean caper (Zygophyllumfabago L.) on seed germination and seedling growth of eastern dodder (Cuscutamonogyna Vahl.)

Abstract
Eastern dodder (CuscutamonogynaVahl.) is a parasitic weed of woody species. The objective of the research was to study allelopathic effects of above ground parts of Syrian bean caper (Zygophyllumfabago L.) on eastern dodder(CuscutamonogynaVahl.) seed germination and seedling growth. Water extracts from leaf, fruit and stem dry powder in five concentrations (0, 2.5, 5, 7.5 and 10 g/100ml) were tested on germination and seedling growth in factorial experiment in completely randomized block design with three replications.The results indicatethereduction of seed germination up to 90.6%. Leaf extract showed higher inhibition impact on seed germination and seedling growth.Also, fruit and stem extracts inhibition on seed germination seedling growth of eastern dodder was significant. By increasing of allopathic plant concentration, seed germination and seedling growth of this parasitic weed was decreased significantly. In all concentrations of all plant parts, seedling growth of eastern dodder was more sensitive thanseed germination.Therefore, allelopathic potential of Syrian bean caper could be used for this parasitic weed management, in order to achieve the goals of sustainable agriculture and environmental conservation.
