Iva xanthiifolia Nutt., popularly known as “ierboaie”, is a neophyte invasive species notorious for being an allergenic weed, identified in the west of Romania, in two locations near Oradea, in Bihor County, near the border with Hungary. This species belongs to the allergenic weeds, being considered by some even more dangerous than Ambrosia artemisiifolia L., the two representing in summer the primary source of allergies, or diseases like hay fever, due to the pollen released in the atmosphere.The research is about the results of the allelophatic effect upon the germination and growth of plants, immediately after springing, viewed as the interaction between the species of Iva xanthiifolia and five other crop plants: wheat (Triticum aestivum L.), rye (Secale cereale L.), barley (Hordeum vulgare L.), rape (Brassica napus L.) and lucerne (Medicago sativa). The experiments that were performed consisted in applying treatments with aqueous extracts obtained from different vegetative organs (roots, leaves, stems and seeds) harvested from Iva xanthiifolia plants. In all cases, the results indicate a rather large inhibitor effect, no matter if the aqueous extracts were obtained from green plants or dehydrated ones.

The present study aimed to evaluate the autotoxic effect of Anagyrus foetida root, flower, and leaves alkaloids on the seed germination and growth of the same species. The pot experiment was conducted for three concentrations i.e. 4, 8, and 12% of aqueous extracts of root, flower, and leaves. Further, the seed and leaves were evaluated for their alkaloids content i.e. cytisine, aporphine, and anagyrine by high-performance liquid chromatography. The results of the study suggested that seed treated by 4% root extract showed a decrease in aporphine, cytisine, and anagyrine. While the seed treated with the flower and leaves extract (12%) showed a lower concentration of all three alkaloids as compared to untreated control. While a mixture of all three parts extracts at 4% concentration showed a minimum concentration of aporphine, cytisine, and anagyrine alkaloids in the treated seeds. Anagyrus foetida roots effectively secret allelopathic compounds which inhibit A. foetida plant germination and growth. The allelopathy effect of plants can be studied in the integrated management of poisonous plants. Results of the study suggested that the farmers should not repeat the A. foetida plantation continue two successive years.
