Abstract

The effect of liquid extracts of two seaweeds, Caulerpa peltata and Gracilaria corticata on seed germination, growth and pigment contents of Greengram (Vigna radiata L.) was studied. The extracts promoted seed germination at lower levels of seaweed liquid fertilizer application. The plant treated with 4% seaweed liquid fertilizer of Gracilaria corticata showed maximum shoot length, ischolar_main length, number of leaves, number of fruits, number of ischolar_main nodules, chlorophyll contents (a,b and total chlorophyll).

Keywords

Abstract

The antibacterial activity of Mimosa pudica and Mimosa invisa were evaluated. The extract of these plants was obtained by using methanol and water as solvents. Antibacterial activity was screened by using agar well diffusion method against pathogenic bacteria, i.e., Bacillus subtilis, Staphylococcus aureus, Klebsiella pneumoniae and Pseudomonas fluorescens. M. pudica and M. invisa showed highest antibacterial activity against K. pneumoniae and B. subtilis respectively. Phytochemical screening revealed that M. pudica and M. invisa, in general, contain active constituents like alkaloids, tannins, flavanoids, steroids, phenols, glycosides, terpenoids, anthraquinones, etc. having a definite specificity.

Keywords
