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.

Após sequenciamento, polimorfismos na região promotora do gene DREB1D (Dehydration Responsive Element Binding Protein) de Coffea canephora Conilon, indicaram a participação de três haplótipos (15, 16 e 17) no controle genético da tolerância à seca nos clones 14 (tolerante a seca) e 22 (sensível a seca), com as combinações de haplótipos 15-16 para o clone 14 e 15-17 para o clone 22. A fim de avaliar a capacidade desses fragmentos controlarem a expressão do gene repórter uidA, 3 construções gênicas, com os diferentes haplótipos do promotor do gene CcDREB1D, foram feitas no vetor binário pBI101 e testadas independentemente via transformação genética de Nicotiana tabacum. Testes histoquímicos em plantas transformadas de N.tabacumT1 indicaram uma forte atividade GUS correspondente ao controle positivo (pBI121) enquanto nenhuma atividade foi detectada para o controle negativo (WT). Os resultados mostraram que, mesmo fracos, os promotores pDREB1D de C. canephora são funcionais em tabaco (N.tabacum), se comportando de forma diferencial entre os haplótipos, sugerindo que os polimorfismos identificados neles são essências na regulação destas sequências. |
