Abstract

Rapeseed (Brassica napus L.) contains allelochemicals that reduces the germination and growth of weed species. An in-vitro experiment was carried out to investigate the effects of different concentrationsof B. napus(L.) water extracts from leaves, stems, roots and flowers on the seed germination and seedling growth of Phalaris minor (Retz.), Convolvulus arvensis (L.) and Sorghum halepense (L.) weeds. All treatments significantly inhibited seed germination, root length, fresh root weight, shoot length and fresh shoot weight of all weed species over the control. The inhibitory effects were concentration dependent. Flower and stem water extracts were most inhibitory to seed germination and root length of all weed species. This work highlighted the allelopathic potential of B. napus extracts for the management of weeds.
