| Abstract | In our state of West Bengal Desmostachya bipinnata L. Stapf (Poaceae), Parthenium hysterophorus L. Asteraceae, Alternanthera sessilis (L.) R. Br. ex DC. (Amaranthaceae), are three profusely growing weeds with potential allelochemicals. An investigation therefore was carried out for the determination and evaluation of their allelopathic potential in terms of their relative allelopathic vigour from a physiological, biochemical (metabolic changes), software prediction and cytological approach. Allelochemicals in various concentrations [1:5, 1:10 and 1:20 (w/v)] of leaf extracts and leachates of the three weeds respectively are tested on Vigna radiata and Senna occidentalis seed germination, TTC stainability and several metabolic parameters like-changes in insoluble and soluble carbohydrates, amino acids, protein, DNA, RNA and enzymes like dehydrogenase,atalase, peroxidase and amylase. Computational tools evaluate numerous compounds for innumerable toxicological end-points. Screening method, using ChemID plus is easy, highlighting compounds for which experimental evaluation is recommendable. It produces a system for predicting the allelochemical toxicity and/or mutagenicity. This system can also give additional information, by identifying genotoxic properties in a fast and convenient way on the basis of the analogus chemical structure prediction. Cytological evaluation of allelopathic potential is done by microscopic study of allelochemical induced alterations of cytological characters of root tip cells of Vigna radiata and Senna occidentalis with particular reference to various anomalies during cell division and chromosomal structural abnormalities i.e. Chromosomal Abnormality Index reveal that Democracy bipinnata > Parthenium hysterophorus > Alternanthera sessilis in terms of allelopathic potential indicating that the monocotyledonous weed Desmostachya is more allelopathically vigorous than the other two dicotyledonous weeds. Parthenium and Alternanthera. Further research might thus be relevant to know the interaction of other invasive dicotyledonous and monocotyledonous weeds on other weed and crop species opening a new plethora of research. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
