Effect of Plant Extracts on Seed Germination and Seedling Growth of Green Gram, Brinjal and Tomato

Abstract

The aim of the present study was to investigate the effect of three aqueous extracts made from three medicinal plants, Acalypha indica (Linn), Calotropis gigantean (Linn) and Zingiber officinalis (Rose). Investigations were conducted on seed germination and seedling growth of some commercially important plants made from green gram, brinjal and tomato. The plant extracts produced great variation in the rate of inhibition on seed germination. The A. indica extract alone showed stimulatory effect on seed germination of brinjal. The growth of seedlings of green gram, brinjal and tomato were adversely affected by selected plant extracts except C. gigantean (Linn) which promoted the seedling growth of brinjal.
