Effect of temperature on germination of golden grass seeds (Syngonanthus nitens (Bong.) Ruhland) originating from the region of Mateiros, Jalapão (Tocantins)

Abstract

Jalapão is a region rich in natural beauty and is in the east of Tocantins, the population practices handicrafts made with golden grass (Syngonanthus nitens) sewn with buriti "silk". Throughout the cerrado, fire is used as part of the management of existing species, for S. nitens popular knowledge states that with the proper use of fire its flowering is stimulated. The research was carried out to contribute to the definitions of management of the species. The germination of S. nitens seeds  from the municipality of Mateiros, exposed naked and in capitula for 10 min at temperatures of 50, 100, 150 and 200 ºC, was evaluated. The viability of S. nitens  seeds submitted in capitula and naked at 50°C for 10 minutes was higher when compared to the other temperatures. The exposure time of the bare seeds and in chapters at 150 and 200 ºC made them unviable.
