PHYTOTOXIC EFFECT OF ANDROGRAPHIS PANICULATA NEES ON METABOLISM OF PARTHENIUM HYSTEROPHORUS L.

Abstract

ABSTRACT The powdered leaves, stem and roots of Andrographis paniculata Nees adversely affected the metabolism of Parthenium hysterophorus L upto 60 DAS. It influenced plant height, leaves number and seeds per plant. The total sugars and lipid contents were decreased in leaves, stem and roots of Pathenium hysterophorus L supplied with Andrographis paniculata Nees residues. While total chlorophylls, polyphenols, total aminoacids and protein contents were greatly reduced as compared to control. The residues of Pathenium hysterophorus L may be used as a potent bioherbicide.
