Effet des extraits de quelques adventices sur la germination et la croissance de plantes d’intérêt agro-alimentaire

Abstract

Weeds are the most important biotic factor responsible for the deterioration of the quality and quantity of crop products. In this context, the objective of our work is to determine the allelopathic potential of Bromus rigidus and Sinapis arvensis weeds on the growth of four plants of agrifood interest; barley (Hordeum vulgare L.), wheat (Triticum durum L.) and tomato (Solanum lycopersicum L.) and coriander (coriandrum sativum L.). The results of our study showed an inhibitory effect of weed extracts used by a reduction in plant biomass. The inhibition of the growth of the plants studied leads us to suggest the use of the weeds studied as natural weed killers against other weeds.
