Abstract: This work had as objective to evaluate the dispersion of the seeds of imbuzeiro (Spondias tuberosa Arruda) for the animals and the survival of plants in caatinga. The work was carried out in the period from October of 2002 to December of 2005 in degraded and native area of caatinga. They had been selected to perhaps, 16 plants of imbuzeiro, being eight plants in each area. In each plant twelve transectos of 1 m of width for 25 m had been demarcated, where the seeds found in the young ground and plants. The used experimental delineation was block-type to perhaps in factorial project 5 x 2, with four repetitions. 1003.5 seeds.m-2 had been, on average, in the first units you show of caatinga native and in caatinga degraded, it was observed, on average, 31.25 seeds m-2. In the native area of caatinga they had been registered 2.5 plants m-2, on average, in the first units you show during the rainy station. The dispersive ones of the seeds observed in the native area of catinga had been the deer-catingueiro (Mazama gouazoubira), the cotia (Dasyprocta cf. prymnolopha), caititu (Tayassu tajacu), the fox (Dusicyon thous), the teiú (Tupinambis merianae), the tatu-peba (Euphractus sexcinctus) of the guará (Procyon cancrivous) the area of caatinga e na área de caatinga degraded the sheep (Capra hircus).Key-words: rain, tree, seedlings, emergency, germination.

Abstract: This study had the objective of evaluating the injuries caused by animals to young imbu tree (Spondias tuberosa Arruda) plants in native and degraded Caatinga areas, between the years 1997 and 2002. One thousand imbu tree scions were planted, being 500 in a degraded Caatinga area at the community of Alto do Angico, Petrolina-PE, and 500 in a native Caatinga area at the Caatinga Experimental Station of Embrapa Tropical Semi-Arid, Petrolina-PE. At every 30 days after having planted the scions, data were collected regarding survival and injuries caused by animals to the plants. The results showed that goats are responsible for the reduction on survival rates and for the slow development of young imbu tree in the degraded Caatinga area. In the native Caatinga area, of the collared peccary (Tayassu tajacu) and armadillo (Euphractus sexcinctus) caused the highest injury levels.

Abstract: The imbu (Spondias tuberosa Arruda) is a native tree of the semi-arid region of the Brazilian Northeast, whose fruit is of great importance for complementing the family income of small farmers. However, its reproductive cycle is still not very well known, especially a function to irrigation supplemental. This work was carried out to help follow the evolution of the reproductive cycle of the imbu, from the emission of the beginning of the floral bud to the ripening of the depending on the application of irrigation. This work was carried the Caatinga Experimental Station, Semiarid Embrapa of 8 plants. In each plant, 100 branches were randomly chosen from different parts of the crown and labelled for phenological data annotation. In the data obtained were determined averages standard deviations and coefficients of variation. The application of supplemental irrigation in imbuzeiro plants can significantly contribute to increase in fruit production.

Abstract: umbu tree is one of the most important species in the brazilian semi-arid region due to its ability to produce fruit in water stress environments. the objective of this work was to estimate outcrossing rates in the s. tuberosa (), by considering the observed and expected frequency of heterozygous in the mother and descent population (m1), respectively, and the estimate of multilocus (m2), to direct programs of conservation and genetic improvement of the species. samples of dna extracted from a maternal population with 96 plants established in 1991, at petrolina, pe, as well as the dna from one descent from each maternal plant were analyzed for the 16 polymorphic aflp bands obtained from aaa_ctg and aaa_ctc primer combinations. in m1, it was considered the frequency of heterozygote estimated by the square root of 1 minus the aflp fragment absence frequency, for the maternal population (observed frequency) and also for the descent population (expected frequency), whereas in the m2, the estimate was obtained by the multilocus estimate (m). the estimates of m1 ranged from 1.74 to 0.50, with mean value of 1.063. because values of above 1.0 are biologically inadequate, it was demonstrated that m1 was not appropriate to estimate . frequencies of pollen and ovule for 15 aflp loci were the same, suggesting good adjustment to the mixed mating model in m2. the rate obtained by m2 was 0.719, which was close to previous estimates with isoenzymes obtained in other umbu tree populations. results point that umbu tree is predominantly an outcrossing species and there is the need for broad samples in order to preserve the genetic variability of this species.

Abstract: Spondias tuberosa Arruda (umbuzeiro), a Brazilian semiarid plant, is a species of great economic, social, and ecological importance. In folk medicine, the leaves have been used in the treatment of diabetes, inflammation, stomach and uterine pains, and constipation. In this study, the antioxidant properties of ethyl acetate and methanol leaves extracts were evaluated in vitro using different methods: free radicals elimination by DPPH and ABTS assays, and transition metal reduction by phosphomolybdenium assay. In addition, a phytochemical study was also carried out. The methanolic leaves extracts showed the strongest antioxidant activity and the higher values for total phenolic and flavonoids. The results showed that S. tuberosa leaves have antioxidant activity and this seems to be related to the phenolic content.

Abstract: Background Studies aimed at investigating the influence of habitat change on species phenology. Studies that investigate people's perceptions of the phenology of certain species still area few; yet this approach is important for effective decision-making for conservation. The aim of this study was to investigate the phenology of Spondias tuberosa Arruda (Anacardiaceae), a native species of economic and ecological importance in northeastern Brazil, in five landscape units (LUs) (Mountain, Mountain Base, Pasture, Cultivated Areas and Homegardens) of a Caatinga region in Altinho, Pernambuco, northeastern Brazil. These data could then be compared with local people's perceptions of the species’ phenophases. Method Collection of phenological data was carried out monthly from February 2007 to January 2009 and included activity, intensity and synchronization of reproductive and vegetative phenophases. Ethnobotanical data were gathered using a collaborative approach to access local people’s knowledge about the species’ phenological schedule. Results There were no significant differences in the intensity of phenophases among LUs, and there was a correspondence between people’s perception of phenophases and the phenological data collected. The data show that the different management practices for LUs did not influence the phenology of the species. Conclusion The main conclusion of this study is the use of traditional knowledge as interesting tool for rapid phenological diagnosis. However further studies need to be developed to test this tool in other environments and cultural contexts.
