Abstract

An experiment has been conducted to assess the Allelopathic potential of Pinus needles on seed germination and early seedling growth of Wheat and Mustard. Phenomenon ofAllelopathy could be defined as involvement of phytochemicals in the growth and development of surrounding plants, which could be direct or indirect. Moreover the effects could be positive or negative. Plants release phyto-chemicals in the surrounding soil and environment. Allelochemicals are primarily phenolic compounds which are involved in causing number of problems, such as reduction in crop production due to changes in chemical as well as microbial composition of soil, changes in the structure of ecosystem and failure in regeneration of natural forests. In the present study we demonstrate the toxic effects allelochemicals from Pinus needles on Wheat and Mustard seeds. The main aim of this study is to draw attention to the allelopathic potential of phenolic compounds present in pine needles in as the main cause of reduction in crop production.
