Dormancy breaking methods for bird of paradise seeds

Resumo


Abstract: The bird of paradise is one of the most commercialized flowers in Brazil. The biggest difficulty in its seed propagation is the low germination percentage that occurs due to the physiological seed dormancy. It is necessary to study methods that can enable the commercial seedlings production from seeds, seeking efficient treatments to overcome dormancy. The aim of this research was the find the best treatment to break bird of paradise’s seed dormancy. It was tested methods of scarification with or without the addition of gibberellin, totaling six dormancy break treatments. The highest germination percentage for bird of paradise seeds is obtained using scarification with sandpaper in the micropyle region with 24 hours of imbibition with gibberellin.

 

Keywords: Physiological dormancy; Strelitzia reginae L., Gibberellin.
