Studies were conducted to evaluate biomass production, tissue phytotoxicity, and allelochemical content of rye (Secale cereale L.) shoots grown in three fertility regimes (low, medium or high) in the greenhouse. Wheeler rye or a polyculture of rye and hairy vetch (Vicia villosa Roth) grown with high
Plants have evolved advanced chemical defence mechanisms, including root exudation, which enables them to respond to changes occurring in their surroundings rapidly. Yet, it remains unresolved how root exudation effects belowground plant-plant interactions. The objective of this study was to
