Abstract: Growth of mam ozinho-de-veado (Jacaratia corumbensis O. Kuntze) in different rooting media were tested with the objective of detecting those that provided better conditions for growth of the mam ozinho. It was used six different compositions for rooting (sands, soil, sands + soil, soil + cattle manure, sands + cattle manure, and sands + soil + cattle manure). The work was accomplished in the period from september of 2007 to December of 2008, in area under screen shadow with reduction of light of 50%, in temperature it sets in Semi-arid Embrapa in Petrolina - PE. The evaluations of growth, height and diameter of the plant; length, diameter and weight of the rooting. A difference was verified in the growth rate of the 365 days, being the rooting with sands + soil + cattle manure, where they happened the largest growth rates. The rooting, the best was it composed with soil + cattle manure, where to the 365 days, it promoted larger growth in mass, height and diameter of the plant.
SUPPLEMENTAL IRRIGATION THE IMBU TREE (Spondias tuberosa Arruda)
Nilton de Brito Cavalcanti,Geraldo Milanez Resende,Luiza Teixeira Lima Brito
Engenharia Ambiental : Pesquisa e Tecnologia , 2011,
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.

Engenharia Ambiental : Pesquisa e Tecnologia , 2009,
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.

Engenharia Ambiental : Pesquisa e Tecnologia , 2009,
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.
