Research on the allelopathic effect among the species Tanacetum vulgare and some agricultural crops
Published November 10, 2010
105-109

The research presents the results of the allelophatic effect upon the germination and growth of plants, immediately after springing, viewed as the interaction between the species of Tanacetum vulgare sin Chrysanthemum vulgare and three other crops: wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), rape (Brassica napus ssp. oleifera L.).... The experiments that were performed consisted in applying treatments with aqueous extracts obtained from the roots, leaves, stems and flowers harvested from T. vulgare plants upon the seeds of the three agricultural crops mentioned before. In all aqueous extracts, the results indicate the presence of some chemical compounds that have inhibiting allelophatic effect. The plants upon which tests were made showed great sensitivity, the results on their germination and growth being significantly negative and highly significantly negative.
The conclusions of this research sustain the idea of setting new research objectives in order to discover the chemical compounds from T. vulgare extracts that have such a stong effect and the possibilities they offer.
