Resumo

Cyperus sp. is one of the world's main weeds, present in many areas, regardless of cultivated agricultural species, and is known to produce allelopathic compounds. The objective of this research was to evaluate the allelopathic effects of Cyperus rotundus alcoholic extract on initial development of canola (Brassica napus var oleifera). The experiment was carried out in Seeds Laboratory of the Fronteira Sul Federal University, Campus Chapecó-SC, with Hyola 571CL cultivar, in competition with Cyperus rotundus extract. The experimental design was completely randomized, with five treatments (0, 25, 50, 75 and 100% of Cyperus rotundus extract) and four replications. Germination, germination speed index, seedling length and dry mass were evaluated. The data were submitted to analysis of variance by the F test, and if significant to 5%, regression analysis was performed. Data expressed as a percentage were transformed into arc sin (x / 100) 1/2, and the analysis was performed with the WinStat program. There is negative interference of the Cyperus rotundus extract on the percentage of normal canola plants. The percentage of germination, rate of germination and dry mass are not altered with the presence of tereza extract, however, there is a reduction in the length of the roots and aerial part of seedlings when submitted to higher concentrations of the extract.
