Abstract

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.
