Trichoderma spp. NA EMERGêNCIA E CRESCIMENTO DE MUDAS DE CAMBARá (Gochnatia polymorpha (Less.) Cabrera)1

摘要

In this work, the objective was to evaluate the effect of Trichoderma spp. isolates on the emergence of plantules and growth of cambará seedlings (Gochnatia polymorpha). For that we used, in a greenhouse, sterilized and unsterilized substrates, where we evaluated the effects of four isolates of trichoderma; TSM1 and TSM2 of Trichoderma viride, 2B2 and 2B22 of Trichoderma harzianum, plus a mix prepared with the mixture of these four isolates, and two commercial products based on trichoderma. Data analysis showed that trichoderma isolates tested did not interfere in plantule emergence, but the isolates 2B2 and 2B22 of T. harzinum present potentials as growth promoters of cambará seedlings.
