Dear Rashida ji, Please check this paper for Allelochemicals of Gliricidia.
http://www.springerlink.com/content/t554w03281740g70/ Take the services of Google scholar and Scirus.com. I have published a lot on different aspects of Allelopathy. For my scientific papers please see this link http://ecoport.org/ep?SearchType=reference&Author=oudhia&MaxList=0&AuthorWild=CO When I started Ethnobotanical surveys, I observed that the Traditional Healers have in depth Traditional Knowledge about plant to plant relationships. They exploit this relationship to enrich plants with desired medicinal properties. I named this knowledge as Traditional Allelopathic Knowledge. Over 7500 research documents based on this knowledge are online through Botanical.com whereas thousands of documents are at pankajoudhia.comand Ecoport. regards Pankaj Oudhia On Wed, Apr 14, 2010 at 7:12 PM, rashida atthar <[email protected]>wrote: > Dr. Gurcharan ji Thank you for explanation of allelopathy phenomenon.
