Abstract

ALLELOPATHIC EFFECT OF AQUEOUS EXTRACTS OF CENTRATHERUM INTERMEDIUM LESS. ON GERMINATION AND SEEDLING GROWTH OF VIGNA RADIATA L.

Remya Krishnan* and Jerry C. Jacson

ABSTRACT

Allelopathy affect various aspects of plants, including occurrence, growth, succession, dominance, diversity and productivity. These effects may be either positive or negative. Many invasive weeds of Asteraceae posses significant alleopathic potentiality. The aim of present study was to investigate the alleopathic potentiality of Centratherum intermedium Less. on germination and growth of Vigna radiata seeds. Different concentrations of C. intermedium aqueous extracts (1%, 2%, 5% and 10%) were prepared and were used for the analysis of allelopathic potentiality. After 7 day’s treatment Germination percentage (GP %), Relative germination percentage (RGP), Vigour index (VI), shoot length, root length, lamina length, total protein and total carbohydrate contents of seedlings were calculated. Significant reduction in seed germination and vegetative growth of Vigna seedlings were noticed in the treated seedlings compared to control. Total protein and carbohydrate contents also showed remarkable reduction in a concentration dependant manner. The observed allelopathic effects could be due to the synergistic effect of their rich water soluble phytochemicals such as alkaloids, tannins, saponins, flavonoids, terpenoids, glycosides and phenols. The FT-IR analysis of Centratherum revealed the presence of alcohols, phenols, alkanes, carboxylic acids, aldehydes, alkenes, nitro compounds, esters, ethers, aliphatic amines and alkyl halides, the FT-IR spectra validated the presence of various phytochemicals in the plant. However, field experiments are necessary for complete evaluation of extract potential and further investigations are needed to analyze how to control this weed.

Keywords: Allelopathy, Aqueous extract, Centratherum, FT- IR, Phytochemicals.
