Abstract:
Cold and hot water extracts from fresh and dry plant parts; natural rain leachates, litter and soil collected from underneath the grass invariably and significantly reduced the germination and early growth of Setaria italica, Dichanthium annulatum, Chrysopogon montanus, Medicago polymorpha and Pinus roxburghii. The number and biomass of root nodules in Medicago polymorpha, M. minima and Melilotus indica decreased in the Imperata-affected soils. Caffeic, ferulic, p-hydroxbenzoic, p-coumaric, vanillic, chlorogenic and syringic acids were identified as the allelopathic agents. Allelopathy by I. cylindrica seems to be one of the factors responsible for interfering with the regeneration of P. roxburghii.
