Desmostachya bipinnata has naturalized as halophytic grass in various saline soils of Pakistan. Allelopathic studies were carried out from aqueous extracts for 24 and 48 h soaking in various experiments using two wheat varieties namely; Ghaznavi and Tatara varieties of wheat as test species. The results suggested that the germination and plumule and radicle growth of test species were significantly reduced. The extracts after 48 h were inhibitory than those obtained after 24 h. Roots of D. bipinnata were more allelopathic followed by stem, leaves and inflorescence. Ghaznavi was susceptible to all the extracts than Tatara
Key words: Allelopathy, Desmostachya bipennata, wheat varieties (Ghaznavi and Tatara) plumule and radicle growth reduction..
