Competitive effect and response in four annual plants
Goldberg, E.D.
Competitive effect and response in four annual plants - 1987 - Printed
Neighbourhood experiments were used to compare the magnitudes of competitiveeffect and competitive response using all pairwise combinations of Papaver rhoeas, wheat and oats as neighbour species, and these 3 species plus Chenopodium album as target species. Over 79% of the variance in target wt was explained by a simple hyperbolic function of neighbour wt or density for 7 out of the 12 species combinations. For all 4 target species, the 2 grass neighbour species always had statistically equivalent competitive effects that were generally greater than the effects of P. rhoeas. For all 3 neighbour species, P.rhoeas was the weakest competitor in
