Description :
Allelopathy is the direct or indirect effect of one plant on another through release of substances in the environment and occurs widely in natural plant communities. The secondary metabolites or natural products involved in allelopathy are called allelochemicals and can be produced in different parts of the plants. The purpose of this study was to evaluate the allelopathic potential of invasive plant weed Trichodesma indicum (L.) R. Br. and Tribulus terrestris L. on seed germination and seedling growth of maize (Zea mays L.) and wheat (Triticum aestivum L.). The laboratory bioassay was conducted to study root, stem, leaf and whole plant aqueous extracts of T. indicum and T. terrestris at 05%, 10%, 15 and 20% concentrations against maize and wheat. It is interesting to note that, the all concentrations of both the weed extracts noticeably inhibited the germination and seedling growth of maize and wheat. Increasing concentrations of extracts (15% and 20%) greatly affected a germination percentage and root shoot length of both the test crops. The plumule length was more affected than radicle growth in all extracts of both the weeds.
