“…The positive influence of vermiculite as a support agent for the in vitro germination of M. urundeuva is in accordance with resulted obtained by Oliveira et al (2014) and Lameira et al (2006) for Hancornia speciosa Gomes and Swietenia macrophylla King, respectively. For these woody species, higher percentage of germination and germination speed index were observed for the treatment that used vermiculite.…”

Myracrodruon urundeuva is a native tree species that stands out for the use of its wood and for medicinal purposes. Due to the multiple uses and extractive exploitation, this species has been threatened with extinction. Thus, it is important to develop strategies in order to ensure conservation and long-term exploitation. This work aimed to establish a protocol of in vitro seed germination and micropropagation of M. urundeuva. Different support agents (vermiculite and agar) and presence of sucrose were tested for in vitro germination, while different concentrations of BAP (0.0, 0.5, 1.0, and 2.0 mg L-1) and explant types (apical and cotyledonary nodes) were tested for multiplication. The use of vermiculite as a support agent favored in vitro germination of M. urundeuva, with germination percentage of 64.3% and 32% for vermiculite and agar, respectively. No significant differences were observed for the different BAP concentrations tested in multiplication and the treatment with 1.0 mg L-1 BAP presented higher values for most variables analyzed. Cotyledonary explants presented higher number of shoots (1.6 shoots) compared to the apical ones (1.1 shoots). Vermiculite may be used as a replacement for agar for in vitro seed germination and the combination of 1.0 mg L-1 BAP and cotyledonary explants may be used for in vitro multiplication of M. urundeuva. Furthermore, studies are needed to improve in vitro multiplication methods of this species.

“…However, mangaba is not demanding in soil fertility because it grows well in poor and acidic soils which are major characteristics of the Brazilian savannah soils (Vieira-Neto, 1994). Silva et al (2011) reported that mangaba emergency percentage, stem diameter and the length of the root system were not significantly affected by different substrates and Oliveira et al (2014) studying the effect of different culture media on the in vitro germination of mangaba seeds observed that there was no difference in the values of germination average time.…”

The unknown potential of the mangaba Hancornia speciosa naturally occurring areas in the mid-north region of Brazil has raised the risk of its extinction and contributed to its underutilization. The objective of this study was to characterize the vegetation structure with naturally occurring mangaba in Recanto, Patizal and Recurso, villages in Morros municipality, State of Maranhão to provide the species proper utilization and conservation. The floristic composition was determined by the quadrants method. Two individuals were selected per quadrant, an adult and regenerating. The phytosociological parameters computed were Relative Density, Frequency and Dominance, Importance Value, Cover Value, the Shannon and Weaver Diversity Index and the Sorensen Similarity Index. The species H. speciosa reached relevant position in all computed parameters in the three sampled villages with importance values varying from 25.15 to 29.38% for the regenerating and from 29 to 56.64% for the adult strata, indicating the species relative ecological importance.

“…Mangaba (Hancornia speciosa) is a fruit tree native to Brazil that has a great social, economic and cultural importance (Soares et al, 2006). Its fruits are nutritious and tasty, used for both fresh consumption and industry, where are widely used for juice and ice cream production (Oliveira et al, 2014). It also has medicinal properties.…”

Mangaba (Hancornia speciosa var. gardneri) is a fruit tree of great social, economic and cultural importance in Brazil. Currently, it is threatened with extinction, so the Brazilian Ministry of the Environment has been encouraging the development of studies that can result in conservation strategies for this genetic resource. Thus, the objective of this work was to accomplish the slow-growth in vitro conservation of nodal segments of mangaba native to Brazilian Cerrado by changes in temperature and culture medium, and after that, to conduct the growth recovery of the explants. In the in vitro conservation stage, two experiments were made to test the temperatures of 25 and 20 °C, in which mangaba nodal segments were inoculated in transparent glass jars containing MS or WPM media at full or half strength, being evaluated at 45 and 90 days of in vitro conservation. In order to verify the growth recovery of the explants, these were transferred to multiplication medium, and evaluated at 60 days. Explants conserved at 20 °C showed small and chlorotic leaves compared to those conserved at 25 °C. The reduction of the conservation temperature provided less development of the explants without affecting the survival rate. Explants conserved in WPM medium showed better responses to growth recovery. The results show that mangaba nodal segments conserved for 90 days on half-strength WPM medium and temperature of 20 °C presented slower growth and a good response to growth recovery stage.
