Allelopathic substances of Parthenium weed and interactions of Solanum melongena.
A study was conducted to explore the post observation indicated that Parthenium hysterophorus strongly react with Solanum melongena. Aqueous extracts of 20 and 40% (w/v) obtained from root extracts of Parthenium increased the total chlorophyll and carotenoids content over control. The toxicity of plant part extracts was also concentration dependent. The inflorescence caused more inhibition than root extract. It appears that allelopathy is the major components of interactions with competitors probably accentuating its effect. It was also found that allelopathy is an important component of the interactions. The inhibitory potential of the extracts was increased with concentration.
