Abstract
Allelopathy is a biological phenomenon in which an organism produces one or more biochemicals that influence the growth, survival, and reproduction of other organisms. This paper reports studies on the allelopathic effects of parsley (Petroselinum crispum (Mill.) Fuss) extracts on several weed species. The effects of extracts obtained from seeds, roots and aerial parts of parsley, were assayed on seed germination, and growth of three common weed species: ragweed (Ambrosia artemisiifolia L.), knotweed (Polygonum aviculare L.) and Johnsonn grass (Sorghum halepense (L.) Pers.). The extracts were prepared with distilled water. For the germination experiments were used Petri dishes and the control treatment was distilled water. The aqueous extracts from roots, stems and leaves and seeds of parsley demonstrated allelopathic potential by inhibiting the germination of weeds seeds. The extracts influenced also the radicle elongation of all tested species. On the other hand, the weed species showed different responses to the treatment with parsley aqueous extracts. The use of allelopathy principles and strategies, such as the use of allelopathic cultivars, intercropping with allelopathic weed suppressive plants, the use of allelopathic cover crops and residues, and rotational sowing of allelopathic crops can play an important role in achieving sustainable and integrated weed control.
