The objective of this study was to evaluate alternative substrates to substitute tree fern fiber for cultivation of hybrids from the Cattleya species. Seedlings were cultivated in polypropylene vases, kept in screen shadowed nursery by a 70% of lighting. The following substrates were evaluated: tree fern fibers; coconut fiber; pinus bark+carbonized rice hull (1:1 v/v); pinus bark+carbonized rice hull (2:1 v/v); pinus bark+carbonized rice hull (1:2 v/v); pinus bark and carbonized rice hull. One year after the experiment, the following parameters were evaluated: fresh matter mass, aerial part height, pseudobulb length, greater root length, number of buds, number of flowers, pH and electric conductivity. The substrate composed of coconut fiber showed better results, and can be used as the alternative substrate to tree fern fiber in the cultivation of Cattleya.
