Resumo

Germination is a factor of great importance in the production of forest seedlings, being correlated, normally, with the type of substrate, as well as the quality of the seed and the climatic conditions to which it is submitted. Thus, the objective was to evaluate the influence of conventional and alternative substrates on the germination of seeds of Clitoria fairchildiana (sombrero). The work was carried out at the Seed Technology Laboratory of the Department of Engineering at the Federal University of Piauí, in the municipality of Bom Jesus - PI. The design used was completely randomized, totaling 10 treatments (T1 - bovine manure; T2 - vermiculite; T3 - washed sand; T4- bioplant ® ; T5 - buriti wood; using 100% of each material; T6 - vermiculite + bioplant ® ; T7 - washed sand + vermiculite; T8 - bioplant ® + washed sand; T9 - bovine manure + buriti wood; using mixtures (50% + 50%); and T10 - washed sand + buriti wood + bovine manure (20% + 40% + 40), with four replicates. Germination (% GERM), first germination count (% PC), germination speed index (IVG), length and dry mass of seedlings were evaluated. The collected data were submitted to the analysis of variance using the ASSISTAT statistical program and the means were compared by the Scott-Knott test, at 5% probability. Treatment T9 promoted a higher percentage of germination and IVG, being indicated for the germination of sombrero seeds. greater initial germination, as well as greater seedling length.
