ALLELOPATHIC EFFICACY OF ZINGIBER OFFICINALE ROSC AQUEOUS LEAF, STEM AND RHIZOME EXTRACT ON EARLY SEEDLING GROWTH OF ZEA MAYS L.
NH Bharath, NK Hemanth kumar,Shobha Jagannath
In the present investigation an attempt was been made to assess the Allelopathic effect of Ginger (Zingiber officinale) on early seed growth parameters of Maize (Zea mays).The aqueous leaf, stem and rhizome extract of ginger showed inhibitory effects on seed germination, root length, shoot length, vigour index, percent totoxicity, fresh weight, dry weight, in maize seedlings. All these parameters were found to be decreased with increasing the aqueous leaf, stem and rhizome extract of ginger. In all parameters maximum value were recorded at control and the minimum value were recorded at 100% concentration. The findings of present study showed that inhibitory effect of ginger aqueous leaf, stem and rhizome extract may be due to the presence of allelochemicals viz. terpinoids, phenols and steroids.
