In Romania, wheat is the main crop, occupying the largest area of arable land. Convolvulus arvensis is a competitive and invasive weed, produces direct and indirect damages to which is added production of allopathic substances. Allelopathy is a natural phenomenon which refers to any direct or indirect effect, positive or negative of a plant (including microorganisms) on the other by the release of chemical compounds in the environment [13]. In most cases, influence is inhibitory, which may explain why some plants do not grow in the presence of others. They may develop a competition eliminating each other to occupy a particular area. It can also affect seed germination, root development and nutrient absorption [3], [4]. Research conducted on the effects of allelopathy revealed that not all weeds are harmful, can be beneficial, some extracts being used for crop production. The objective of this study is to evaluate the allelopathic effects of the extracts of bindweed on germination and plant growth of wheat. In order to accomplish the study were placed experiences with wheat under laboratory conditions. For the preparation of extracts was used 50 g of the ground material added to 800 ml of distilled water and placed on shaker for 24 hours, after this time period filtration was performed. The extracts used in the study were different throughout vegetative organs (leaves and whole plant) of Convolvulus arvensis and through the four concentrations: 5%, 25%, 45%, 65%. From the study conducted was observed that germination, shoot length and dry mass of wheat plants were significantly affected by the type and concentration of the extract. The highest inhibitory effects were recorded in variants treated with extracts from leaves and whole plant in concentration 65%.
