Germinação de semente de seis espécies florestais

Abstract

Forest species play an important environmental and ecological role in the conservation of water, soil and biodiversity. The low number of plantings of these species is associated with a lack of knowledge, ranging from favorable conditions for their seeds to germinating to suitable requirements for planting in different locations. The study of germination and vigor of the seeds are fundamental to understand the ideal conditions for control and storage, allowing success in the silvicultural production chain. In view of the above, the objective of this work was to test protocols for seed germination of six forest species. A germination test was performed on a germitestR paper roll with Apuleia leiocarpa, Mimosa Caesalpiniifolia, Copaifera langsdorfii, Ormosia arborea, Plathymenia reticulata and Parkia Pendula seeds, with three previously determined seed qualities (high, medium and low) in randomized blocks, with three replicates. The germination protocols developed for breaking and overcoming dormancy were efficient in forest seeds. There is variation within the same species to the detriment of the physiological quality of the seeds.
