Abstract
Pterodon pubescens is a native species, popularly known as “faveiro”, “sucupira-branca”, “fava-de-sucupira”, “sucupira”, and “sucupira-lisa”, belonging to the family Leguminosae-Papilionoideae (Fabaceae). This study aimed to analyze the effect of different treatments on the breaking of seed dormancy in Pterodon pubescens (Leguminosae, Papilionoideae). The seeds were collected in four places in the municipality of Cáceres (Mato Grosso, Brazil). They were selected by flotation or deposition in a container with water, washed with sodium hypochlorite (2% active chlorine), and subjected to five treatments, as follow: (T1) control, (T2) seeds had their woody integument removed and were washed with detergent; (T3) seeds were scarified and immersed in a container containing 500 ml of cola-based soft drink, for an hour and a half; (T4) seeds had only their integument removed; and (T5) seeds were subjected to scarification, using a file, until the embryo was visible. T2 and T4 were the most effective treatments for the emergence of P. pubescens seed.
Highlights
Pterodon pubescens (Benth.) Benth. is native to Brazil, popularly known as “faveiro”, “sucupira-branca”, “fava-desucupira”, “sucupira”, and “sucupira-lisa”, and belongs to the family Leguminosae-Papilionoideae (Fabaceae)
Because of Pterodon pubescens (Benth.) Benth. is important for the restoration of degraded areas and for having tegumentary dormancy, this study aimed to analyze the effect of different treatments on the breaking of seed dormancy in Pterodon pubescens (Benth.) Benth. (Leguminosae, Papilionoideae)
During the experimental period (70 days), the results showed a statistically significant difference between treatments
Summary
Pterodon pubescens (Benth.) Benth. is native to Brazil, popularly known as “faveiro”, “sucupira-branca”, “fava-desucupira”, “sucupira”, and “sucupira-lisa”, and belongs to the family Leguminosae-Papilionoideae (Fabaceae). Is native to Brazil, popularly known as “faveiro”, “sucupira-branca”, “fava-desucupira”, “sucupira”, and “sucupira-lisa”, and belongs to the family Leguminosae-Papilionoideae (Fabaceae). This species occurs in the states of Minas Gerais, São Paulo, Goiás, and Mato Grosso do Sul, especially in the Cerrado and in the transition to the semi-deciduous forest in the Paraná basin Lorenzi (2002). This plant has potential for naval and civil construction, bridges, charcoal, landscaping, including for composing lists of species for the restoration of degraded areas. Some of the compounds in its seed showed efficacy against schistosomiasis Denny (2002)
