Resumo: | The use and production of agroecological seeds are promising alternatives to small farmers in organic growth system. In this context, this work aimed to verify the performance of agroecological seeds of Chinese cabbage, associated with the size of the tray, evaluating the characteristics of the seedlings: percentage of emergence, shoot height, root length, and fresh and dry weights. The experiment was conducted in a greenhouse at the Department of Agronomy of UNICENTRO in Guarapuava, Paraná State. We used a 2 x 2 completely randomized factorial design, with five replicates and 16 seeds per plot. The first factor was the origin of the seeds (agroecological and conventional), and the second factor was two trays (128 and 200 cells). Seedlings from agroecological seeds showed high percentage of emergence, shoot height and fresh weight compared to conventional seeds. About the size of the tray, it was verified that the trays of 128 cells are more effective to get vigorous seedlings, due the better results in shoot height, root length and fresh weight. There was no significant interaction between seed type and size of the tray. Thus the agroecological seeds are a viable alternative for the production of Chinese cabbage seedlings.
