摘要：

Association with Parthenium hysterophorus L. caused retarded growth and nodulation in bean (Phaseolus vulgaris var. 'Burpees Stringless') the inhibition decreasing with increasing distance from the weed. Leachate collected from Parthenium grown pots also caused similar inhibition in bean growth. The inhibitory nature of the root exudate was confirmed under sterile cultural conditions by its effect on wheat (Triticum aestivum var. 'UP301') seedling growth. At the rosette and flowering stage of the weed there was maximum exudation of inhibitors which remained active for about thirty days. © 1979 Martinus Nijhoff Publishers.
