Resumo:
The Caatinga has undergone changes over the years as a result of various factors
including the extraction of wood for charcoal production, rudimentary practices of agriculture and
livestock, which has caused the destruction and distortion of plant cover. In this regard, our aim was
to this research, studying the physiological maturity of seeds Mimosa tenuifloraWilld., regarded as
a native species, thus contributing to the conservation of genetic diversity and richness of woody
species in Caatinga Paraíba. The work was performed at Stone Creek Accomplished in the
municipality of Sume-PB. The laboratory stage was performed at the Laboratory of Ecology and
Botany (CDSA / UFCG). Crops began to seventh days after anthesis (DAA) and extended until 35
DAA, with the following parameters: the color, the water content of the seeds, as well as the
physiological quality. According to the data obtained it was found that the physiological maturity of
seeds occurred at 35 days after anthesis, since from this period were maximum values of
germination and vigor.
