Allelopathic effect of Parthenium hysterophorus L. on photosynthetic pigments and biochemical constituents of Vigna aconitifolia L.
Journal Title: International Journal of Life Science - Year 2017, Vol 5, Issue 4
Abstract
Allelopathy play a significant role in agro-ecosystem, and affects the growth, quality and quantity of the products by the interactions among crops and weeds. Parthenium hysterophorus L., is one of the obnoxious weed. The fresh aqueous extracts in the concentration of 5%, 10%, 15%, 20% were tested against photosynthetic pigments and biochemical constituents in Vigna aconitifolia L. The seeds soaked in above concentrations for 4 and 9 hrs. The seven days old seedlings were used for analysis of photosynthetic pigments and biochemical constituents. This study indicated that the higher concentration of leaf extract of Parthenium hysterophorus L. i.e. 20% was more inhibitory than control. An increased concertration of extract decreased the photosynthetic pigments, carbohydrate, and enzymes in Vigna aconitifolia L. This indicates that allelochemicals are present in the aqueous extract of Parthenium hysterophorus as it shows inhibitory effect on plant growth.
