    • Abstract


      The interference between wheat andChenopodium album was studied in pure and mixed stands at two nutrient levels. Wheat responded to density by plasticity whileC. album responded both by mortality and plasticity. In mixtures, crop had an adverse effect on survival and yield of the weed, though to a lesser degree the effect weed on the crop was also noticed. The ecological aspects of the mortal and plastic responses of the competing species are discussed.
