Sobrevivência e crescimento inicial de quatro espécies lenhosas nativas cultivadas em solos degradados

Abstract

The current model of development of the humanity is already characterized as unsustainable and imposes on us the necessity of a new consciousness concerning the exploiting and producing of natural resources. In this work, the behavior of four native multipurpose woody species have been evaluated: red water tree (Anaderanthera macrocarpa Benth), Brazilian pepper tree (Schinus terebinthifolius Radii), cedar (Cedrela fissilis Vell.) and gonçalo alves (Astonium faxinifolium Schott.), in degraded pasture areas, submitted to different intervals , in Cruz das Almas-BA. The cuttings produced in the FURB nursery, have been planted in the mixed planting system, in alternate lines, at intervals of 3,0 m x 1,5 m; 3,0 m x 2,0 m; 3,0 x 2,5 m and 3,0 m x 3,0 m. The evaluations werw done at 6, 12 and 18 months of age.The species studied showed significant differences between the means of survival, diameter and height in the different periods. The potential for establishment of ecological adaptation and growth rate of the species studied werw shown to be differentiated. The survival proved to be an important indicator of sustainability in determining the potential of establishment of native forest species. The pepper tree species, and gonçalo angico show good survival rate and increase in diameter and height, with potential for planting in disturbed environments. New studies related to nutrition, silvicultural treatments and management systems are useful in the recommendation of plantations with the species studied and proven results.
