Allelopathic effect of lambsquarter (Chenopodium album L.) and field bindweed (Convolvulus arvensis L.) on germination
and initial development of Camelina sativa by using leaves, stem, whole plant aqueous extracts and soil incorporated weed
residues was studied in petri dish and pot bioassay. In petri dish bioassay, different concentrations (2.5%, 5%, 7.5%, and 10%)
of aqueous extracts of stem, leaves and whole plant of both weed species were applied on camelina seeds. Among these, 10%
whole plant extracts had shown a significant reduction in seed germination and initial growth of camelina. Moreover, weed
residues incorporated in soil had inhibitory effect on growth and yield contributing attributes of camelina. Comparatively larger
amount of various phenolic acids was determined in whole plant extracts of both weeds by GC-MS. Hence, the results revealed
that C. album and C. arvensis are rich source of phenolic acids that greatly inhibited antioxidant activity which ultimately
adversely affected the germination; seedling development and seed yield of camelina.
