Abstract

NUNES, Yule Roberta Ferreira et al. SURVIVAL AND GROWTH OF SEVEN NATIVE TREE SPECIES IN A DEGRADED AREA IN TROPICAL DRY FOREST, NORTHERN MINAS GERAIS. Rev. Árvore [online]. 2015, vol.39, n.5, pp.801-810. ISSN 0100-6762.  http://dx.doi.org/10.1590/0100-67622015000500003.

This study aimed to evaluate the growth and survival of seven native tree species in different treatments in a degraded area at COPASA Reserve (Juramento, MG). Approximately 1.2 ha area was used, where 899 seedlings were planted of seven native species (Anadenanthera colubrina, Copaifera langsdorffii, Dilodendron bipinatum, Miracrodruon urundeuva, Pterogyne nitens, Schinopsis brasiliensis and Senegalia polyphylla) followed for 24 months. The area was divided into five plots of 0.24 ha, which represented the following treatments: (T1) plot sown with grass (Brachiaria sp.); (T2) plot where the pits were treated with soil conditioner; (T3) plot sown with grass and legumes (Cajanus cajan) together; (T4) plot sown with legumes; and (T5) control. The mortality percentage was higher in T2 and lower in T3, and the species C. langsdorffii (43.66%) and S. brasiliensis (11.64%) were the ones with higher and lower mortality rate, respectively. The growth (height and diameter) of seedlings was higher in T2 (24.32 ± 26.05 cm and 0.51 ± 0.37 mm; respectively) and lowest in T1 (10,82 ± 22,57 cm and 0,26 ± 0,27 mm; respectively). The species with the largest growth in height were A. colubrina and S. polyphylla, and D. bipinatum and S. brasiliensis showed the highest growth in diameter. Pterogyne nitens showed the lowest growth, and highest mortality, presenting low ability to establish in degraded environments.
