BERNARDINO, Daíse Cardoso de Souza et al. Growth and seedling quality of Anadenanthera Macrocarpa (Benth.) brenan in response to basis saturation of substratum. Rev. Árvore [online]. 2005, vol.29, n.6, pp.863-870. ISSN 0100-6762.

The present work was developed with the objective of verifying the influence of the basis saturation of substratum on the growth and seedling quality of Anadenanthera macrocarpa (angico-vermelho). A complete randomized design with four replications per treatment was utilized. Three soils were used as substratum, and for each the original saturation was risen to the following values: Distrofic Latosol, 30.0, 50.0 and 70.0%; Alic Latosol, 25.0, 45.0 and 65.0%; Claysoil, 50.0, 60.0 and 70.0%. Seedlings morphological parameters were evaluated, their relationships and the Dickson's quality index . The base saturation had no influence on any of the studied parameters when the argisoil substratum was used. Except for the diameter, the rise in base saturation affected significantly, in a linear way, the morphological parameters and its relationships, as well the Dickson's quality index for seedlings produced in the distrofic latosol. For the alic latosol the best results for growth and quality were found with 50.0% base saturation.

Keywords : Base saturation; seedling quality; angico-vermelho.
