Abstract A major challenge for the forestry sector is to restore forest cover in degraded areas. In this regard, the adoption of mixed plantations is an opportunity to combine the obtaining of services and products from the forest, providing ecological and socioeconomic advantages. Thus, our objective was to evaluate the growth of native forest species in mixed plantations in Brazilian Savanna. The study was carried out in an area of 4.8 ha with about thirty species planted in spacing 3 × 3 m, located in Chapadao do Sul/MS. At 6.4 years after planting, in 15 randomized plots of 300 m2, the diameter at 1.3 m above ground (DBH), equivalent diameter (DBHeq), total height (H), number of stems (NSI), wood volume (V), biomass (B), carbon (C), and carbon sequestration (CO2) of the trees were measured. Descriptive statistics of the variables were carried out by using boxplot diagrams and principal component analysis (PCA) to group the species according to their growth. The stocks of V and B were 114.03 m3 ha−1 and 52.99 Mg ha−1, respectively. Thus, the mixed planting of native forest species is efficient for recomposing deforested areas, especially as regards biomass accumulation and carbon stock. The species used in mixed planting present different growth form, which were separated by PCA into four groups. DBHeq was the variable that most influenced the differentiation of species into groups. The species Heliocarpus popayanensis, Croton floribundus, Guazuma ulmifolia, Senegalia polyphylla, Enterolobium contortisiliquum, Anadenanthera colubrina, Ceiba speciosa, Anadenanthera peregrina, Gallesia integrifolia and Peltophorum dubium showed the highest growth in the study area.

巴西稀树草原混交林中原生林种的生长

摘要 林业部门面临的一个主要挑战是恢复退化地区的森林覆盖。在这方面，采用混合种植园是一个机会，可以结合从森林中获取服务和产品，提供生态和社会经济优势。因此，我们的目标是评估巴西稀树草原混合种植园中原生森林物种的生长情况。该研究是在位于 Chapadao do Sul/MS 的 4.8 公顷区域内进行的，种植了大约 30 种植物，间距为 3 × 3 m。种植后 6.4 年，在 300 m2 的 15 个随机地块中，地上 1.3 m 处的直径 (DBH)、当量直径 (DBHeq)、总高度 (H)、茎数 (NSI)、木材体积 (V)、测量了树木的生物量 (B)、碳 (C) 和固碳 (CO2)。通过使用箱线图和主成分分析 (PCA) 根据生长情况对物种进行分组，对变量进行描述性统计。V 和 B 的库存分别为 114.03 m3 ha-1 和 52.99 Mg ha-1。因此，本地森林物种的混合种植对于重构森林砍伐地区是有效的，特别是在生物量积累和碳储量方面。混合种植所用的物种呈现不同的生长形态，通过PCA将其分为四组。DBHeq 是对物种分化成组影响最大的变量。种为 Heliocarpus popayanensis、Broton floribundus、Guazuma ulmifolia、Senegalia polyphylla、Enterolobium contortisiliquum、Anadenanthera colubrina、Ceiba speciosa、Anadenanthera peregrina、
