SCREENING OF ALLELOPATHIC ACTIVITY OF CARDIOSPERMUM HALICACABUMLINN. (KAPALPHODI) ON TRITICUM AESTIVUM (WHEAT) AND VIGNA RADIATA (MUG)

Abstract

An organism that generates one or more biochemicals that affect the development, survival, and reproduction of other species is said to exhibit allelopathy. These biochemicals, also known as allelochemicals, can affect the target organism in both positive and negative ways. Allelopathic effect of Cardiospermum halicacabumLinn.(Kapalphodi) was studied in aqueous extract at various concentrations on germination percentage and growth of plumule and radicle (In vitro and In vivo) on Triticum aestivum (Wheat) and Vigna radiata (Mug). Germination percentage, plumule growth and radicle growth of Triticumaestivum (Wheat) and Vigna radiata (Mug) were significantly affected by flavonoids present in aqueous extract of Cardiospermum halicacabumLinn.(Kapalphodi)at higher concentrations with respect to control; In vitro and In vivo. Flavonoids in aqueous extract of Cardiospermum halicacabumLinn.(Kapalphodi)were confirmed by using IR spectroscopy.
