Open publisher page 92 citations

Abstract

The allelopathic potential of wheat [Triticum aestivum(L.) ‘Doublecrop′] straw residue was evaluated on weed-seed germination and seedling growth. The inhibition of weed-seed germination and seedling growth was extract-, species-, and temperature-dependent. The extracts prepared by agitating and soaking caused greater inhibition than those obtained by leaching. The descending order of species susceptibility was ivyleaf morningglory [Ipomoea hederacea(L.) Jacq.], velvetleaf (Abutilon theophrastiMedic.), pitted morningglory (Ipomoea lacunosaL.), hemp sesbania [Sesbania exaltata(Raf.) Cory], sicklepod (Cassia obtusifoliaL.), and Japanese barnyard millet [Echinochloa crus-gallivar.frumetaceae(Roxb.) Link]. Incubation at 35 C caused the greatest inhibition of germination and growth.
