Notas: In this dissertation analysed the allelopathic effects of the fruition of fungus Tuber melanosporum Vittad., more commonly known as black truffle, in both quantitative and qualitative terms. To this end, experimental trials have been conducted in order to determine the germination porcentage and root dry weight and upper part of seeds, bulbs and tubers of the following weeds: Bromus tectorum, Convolvulus arvensis, Cyperus rotundus, Desmazeria rigida, Galium aparine, Lolium rigidum and Oxalis latifolia, which were added to the test together with different amounts of truffle, 1 to 4 grams, as well as a control sample. Once the results of these experimental trials were obtained, a statistical analysis was carried out and whose results confirmed the allelopathic effects of the truffle before the weed. Having a high concentration of truffle produced a decrease in the germination of all the weeds, except L. rigidum and C. rotundus. Concerning the length, all the weeds diminished both the root and the coleoptile, except C. rotundus whose roots grew in size. Regarding the weight, all the weeds reduced it both the root and the coleoptile, expect C. rotundus whose roots gained weight.
