Mahogany is one of the most valuable woods and was widely used until it was included in Appendix II of the Convention on International Trade in Endangered Species as endangered species. Mahogany wood sometimes is traded under different names. Also, some similar woods belonging to the Meliaceae family are traded as ??mahogany?? or as being of a ??mahogany pattern??. To investigate the feasibility of the use of near infrared spectroscopy for wood discrimination, the mahogany (Swietenia macrophylla King.), andiroba or crabwood (Carapa guianensis Aubl.), cedar (Cedrela odorata L.), and curupixa´ (Micropholis melinoniana Pierre) woods were examined. Four discrimination models based on partial least squares-discriminant analysis were developed based on a calibration set composed of 88 samples and a test set with 44 samples. Each model corresponds to the discrimination of a wood species from the others. Optimization of the model was performed by means of the OPUS software followed by statistical analysis software (Matlab). The observed root mean square errors of predictions were 0.14, 0.09, 0.12, and 0.06 for discriminations of mahogany, cedar, andiroba, and curupixa´, respectively. The separations of the species obtained based on the difference in the predicted values was at least 0.38. This makes it possible to perform safe discriminations with a very low probability of misclassifying a sample. This method can be considered accurate and fast. |

Genetic parameters and genotypic values of fruits from umbu-cajazeira clones were determined using the restricted maximum likelihood/best linear unbiased prediction (REML/BLUP) method, from the morphological, physicochemical and chemical characterization of fruits. The experiment was composed of six experimental clones, in three randomized complete block designs and three replicates per plot in an unbalanced arrangement in Ipanguaçu/RN, due to non-fructification of some clones of the experiment. Morphological, physicochemical and chemical characterization of 20 fruits of each clone was performed. The variance components for REML and medium components (BLUP), were estimated using the mixed model?s method REML/BLUP. The three best clones selected were from Serra do Mel, Açu, and Carnaubais. The method used allowed selection of clones with high soluble solids content and pulp yield based on the genotypic value of clones. Fruit clones from Serra do Mel can be used for pulp processing or fresh consumption. The Açu clone showed a high pulp yield and is recommended pulp processing. Carnaubais, Alto do Rodrigues, and Ipanguaçu generated fruits for fresh consumption. |
