摘要: Seeds of Papaver rhoeas, P. dubium, lecoqii, argemone and apulum were sown in garden plots at a range densities pure stands mixtures two species. The plants reacted to density by reduced chance establishment plastic reduction plant weight capsule numbers the species did not differ their reactions stands. In mixed populations was when its own mixture increased associated exerted less significant influence. lower proportion gave more successful from seed it is argued that persistence therefore favoured comparison with
