This study aimed to evaluate the effects of different spacings on wood productivity of two hybrid clones of Eucalyptus, namely E. brassiana × E. urophylla and E. grandis × E. camaldulensis, in the Araripe Plateau. The field trials were established in February 2006 at the Experimental Station of Araripina (latitude: 7°27?50?S; longitude: 40°24?38?W, altitude: 828 m), belonging to the Agronomic Institute of the State of Pernambuco - IPA. Five spacings were tested: 3.0×2.0, 3.0×2.5, 3.0×3.0, 3.0×3.5 and 3.0×4.0 m. The experimental design adopted for both trials was randomized blocks with four replications and plots of 64 plants. The effective areas ranged from 216 to 432 m2, and the total experimental area of 11,520 m2. At the age of four years it was found that there were no statistical differences among the means for the variables evaluated in E. brassiana × E. urophylla. For survival, total height, DBH, wood production and mean annual increment the means were 93%, 14.8 m, 12.3 cm, 98.7 m3 ha-1 and 24.7 m3/ha y-1, respectively. For E. grandis × E. camaldulensis, the means for the same variables previously described were 89.4%, 13.9 m, 12 cm, 83.3 m3 ha-1 and 20.8 m3/ha y-1, respectively. Differently from the first, for this hybrid only the survival and height means did not differ significantly from each other. Specifically for DBH, it was noted that the highest value of 13.2 cm, corresponding to the spacing 3.0×4.0 m, did not differ statistically of 12.9 cm obtained from the spacing of 3.0×3.5 m. Nevertheless, these values were significantly different from the others. The highest production of wood was 105 m3 ha-1 at the spacing 3.0×2.0 m, however, there is no significant difference comparing to 86.3 m3 ha-1 achieved at the spacing 3.0×2.5 m. Likewise, the mean annual increment (MAI) increased inversely to the spacing. We concluded that the number of plants per hectare plays an emphatic role in increasing the wood productivity of these two hybrids at this stage of development.

PHENOLIC ACIDS, FLAVONOIDS AND ANTIOXIDANT ACTIVITY IN HONEY OF Melipona fasciculata, M. flavolineata (Apidae, Meliponini) AND Apis mellifera (Apidae, Apini) FROM THE AMAZON. Honey produced by three stingless bee species (Melipona flavolineata, M. fasciculata and Apis mellifera) from different regions of the Amazon was analyzed by separating phenolic acids and flavonoids using the HPLC technique. Data were subjected to multivariate statistical analysis (PCA, HCA and DA). Results showed the three species of honey samples could be distinguished by phenolic composition. Antioxidant activity of the honeys was determined by studying the capacity of inhibiting radicals using DPPH assay. Honeys with higher phenolic compound contents had greater antioxidant capacity and darker color. |
