Stryphnodendron adstringens is a native species from Caatinga and Cerrado biomes. The chemical composition of species is variable and depends on the part of the tree, as well as on genetic and soil characteristics related to the origin of the population. This paper describes the influence of toposequence position of trees on the discrimination of wood and bark samples based on visible (VIS), near-infrared (NIR) and mid-infrared (MID) spectroscopy. A total of 28 trees were collected in the northern part of Cerrado State Park in the municipality of Jaguariaíva, Paraná state, Brazil, in different types of soil, at seven positions (0, 100, 200, 300, 400, 500 and 600 m) of the toposequence. The results showed the influence of the position of trees. The bark was classified as dark brown and the wood as rose-grey. VIS spectra was not efficient in sample discrimination. The Principal Component Analysis (PCA) of NIR spectra presented two groups that can be related to the the type of soil: (i) 0-300 m - Red-Yellow Latosol and Haplic Cambisol; (ii) 400-600 m - Red Latosol. MID infrared spectra of bark also showed the distinction of two previous groups; and analysis based on wood spectra of trees collected on 0-100m presented discrimination from other positions.

The objective of this study was to evaluate N, P and K requirements for initial growth of A. angustifolia , as well as symptoms of nutritional deficiency. Three experiments were conducted to evaluate growth response of the species to N, P and K application. Five rates of each element were tested individually. P and K were applied once by mixing with soil before transplanting seedlings, and N was divided into three applications. Six-month-old seedlings (20 cm height) were transplanted into pots containing 16 dm -3 of soil. The response to nutrient applications was monitored by measuring plant height and basal diameter for 16 months. At the conclusion of the experiment, seedling dry mass (roots, needles, branches, and stem), seedling quality index, and nutritional deficiency symptoms were evaluated. Chlorophyll relative index (CRI) and needle color were also measured in the N experiment. Increased plant quality was only observed for N (up to 1.238 mg dm -3 ) and P fertilization (up to 472 mg dm -3 ). Small needles, chlorotic, and premature death of lower branches were the main symptoms for N deficiency, while dark green needle coloration, sparse secondary branches, and short internodes characterized P deficiency. Results suggest that nursery applications of N and P are required to improve the growth and quality of plants.
