| Popis: | The Brazilian copal is a tree fruit species that can be used for various purposes. The study evaluated protected environments and substrates in forming Brazilian copal seedlings (Hymenaea courbaril), at the State University of Mato Grosso do Sul, Cassilândia-MS, from January to March, 2014. Two greenhouses were used: (A1) agricultural greenhouse covered with aluminized thermal reflector screen of 50% shading and (A2) agricultural greenhouse covered with black screen of 50% shading. Inside the greenhouses, substrates derived from mixtures of cattle manure, soil, medium vermiculite, super fine vermiculite and washed fine sand were tested. For each cultivation environment, a completely randomized experimental design was used. The environments were compared by combined analysis. Emergence parameters, growth, phytomass and biometric relations were evaluated. The best seedlings were formed on the substrates containing 10 or 20% of cattle manure in the mix. Substrates containing 50% of cattle manure in the mixture did not favor the development of seedlings in the greenhouse with black screen. The best seedlings have been formed in the protected environment of aluminized screen coverage, with higher air and total phytomass, and Dickson quality index. Larger seedlings in height, with more leaves were formed in the protected environment with black screen coverage. |
