Produção de sementes de árvores ornamentais Bauhinia galpinii, Senna seamea e Pericopsis angolensis a partir de exemplares distribuídos pela cidade de Maputo

Abstract

The aim of this work is to evaluate the possibility of producing ornamental tree seeds from specimens distributed throughout Maputo City, taking as an example the species: Bauhinia galpinii, Senna seamea and Pericopsis angolensis. To this end, in the streets of Maputo City, 30 specimens were phenotypically selected in continuous strips of each species. From these, the total height, DBH, crown diameter were measured and the production of fruits and seeds was estimated for each individual. For Bauhinia galpinii, there were 8.1 m of average total height, 36.9 cm of average DBH, and 6.2 m of average crown diameter; the average production of fruits and seeds was about 3673 fruits and 35499 seeds per tree;

For Senna seamea, there was an average total height of 11.2 m, average DBH was 49.5 cm, and average crown diameter of 6.9 m; the average production of fruits and seeds was about 2679 and 46752 respectively; For Pericopsis angolensis, the mean total height was 7.3 m, the mean DBH was 35.5 cm, and 7.1 m mean crown diameter; relatively the average production of fruits and seeds was 8039 fruits and 19271 seeds per tree; The correlation between dendrometric parameters and the production of fruits and seeds, in general, is positive at 5% significance, in all species; All species showed to be potential for seed production, and show variation within species, with the species Bauhinia galpinii showing the greatest variation (TRADUÇÃO NOSSA)
