Abstract:

Allelopathic compounds can inhibit or stimulate growth of nearby plants of the same or other species. In this connection, experiments were conducted to inspect the allelopathic effect of Euphorbia helioscopia L. aqueous extract and leaf dry powder on seeds and pre-germinated seeds of Avena fatua L., Rumex dentatus L., Triticum aestivum L., Helianthus annuus L. and Zea mays L. The aqueous extract of Euphorbia helioscopia significantly suppressed the germination and subsequent growth of R. dentatus and A. fatua. Radicle and plumule growth of H. annuus and Z. mays decreased when E. helioscopia aqueous extract and leaf dry powder were applied to seeds, while remained unaffected when applied to the pre-germinated seeds. The aqueous extract showed non-significant effect on radicle and plumule growth of wheat seedlings. It conclusion, aqueous extract of E. helioscopia has the potential to be used as a source of weed management.
