DEVELOPMENT OF MANGUE SEEDLINGS IN DIFFERENT VOLUMES OF CONTAINERS IN TAMATATEUA, NORTH OF BRAZIL.

Abstract

The volume of container to be used in the production of seedlings should be according to their physiological needs and must properly support and nurture the seedlings, providing a higher growth rate and survival post-planting. This study investigated to test different volumes of containers in the production of Rhizophora mangle, Avicennia germinans and Laguncularia racemosa seedlings in nursery. The experiment was conducted in the city of Bragança (PA). During 10 months, bi-monthly monitoring was performed, evaluating the survival and growth of species in height. The data related to plant height and survival were submitted to analysis by the Tukey test at 5% performed by the statistical software GENES, Windows version. In the 12.000 cm³ packages R. mangle seedlings showed a high survival rate. The survival rate for A. germinans seedlings was greater than 69% regardless of the volume of containers used. The height growth of the R. mangle and A. germinans seedlings occurred in the different volumes of containers, however the results showed that the container volume of 12.000 cm³ is the most suitable container for the cultivation of R. mangle and A. germinans seedlings, as a function the survival and permanence of the seedlings in the nursery.
