Assessment of polar and non-polar extract fractions of Limnophila indica for its in-vitro herbicidal efficacy
Randeep Kumar, Ravendra Kumar and Om Prakash
The present study was carried out for analysis of hexane and methanol extract of Limnophila indica and evaluated for its in-vitro herbicidal efficacy against Raphanus sativus in terms of three parameters that is inhibition of germination, inhibition of coleoptiles growth and inhibition of radical growth. The plant extracts of the plant L. indica exhibited the significant potential to suppress germination at all tested doses of the plant extracts having broad range percent inhibition for all the samples tested. The results were quiet satisfying as validated by their IC50 values in all the three parameters. Higher the IC50 value lower will be the herbicidal activity. The order in which the samples exhibited herbicidal potential is LIHE (413.26±90.10ppm) > LIME (620.18±86.86ppm) for % inhibition of germination, LIHE (366.67±59.39ppm) > LIME (448.86±19.78ppm) for % inhibition of coleoptiles growth and LIHE (416.93±69.76ppm) > LIME (349.25±120.56ppm) for % inhibition of radical growth. All the inhibition data were tested to be significantly different as analyzed via two factor analysis with replication (p< 0.01 and p< 0.05).
