Dicksonia sellowiana Hook, tree fern, is a tree-sized fern that occurs in the Upper Montana Araucaria Forest, a subdivision of the Atlantic Forest biome. It is a species of high ecological importance, since in addition to favouring nutrient cycling, it serves as a substrate for several epiphytes. It also has medicinal potential and, having gone through an intense period of exploration, with the cutting of its caudex for the production of decorative vases, it is currently listed as an endangered species, in addition to having been studied in an

Different planting spacings of forest species can act differently in increasing or decreasing the levels of chemical elements in the soil, which affects its composition and quality. Defining adequate planting spacing for a given forest species is important, not only to optimize productivity, but also for decision-making in the recovery of degraded soils. This work aimed to evaluate the changes occurring in the chemical properties of a soil planted with Tachigali vulgaris at different spacings, approximately seven and a half years old. The work was carried out at Fazenda Gênesis, in the municipality of Dom Eliseu (PA). Soil samples were collected at four depths in 30 m x 50 m plots with four replications for each spacing. Sixteen soil collection points were randomly selected for each plot. The soil samples were sent to the Embrapa Amazônia Oriental laboratory where chemical analyzes were carried out. The PCA results showed that Al was negatively correlated with other soil attributes at all depths. The two-way ANOVA graphs (p < 0.05) demonstrated that the 4 m x 3 m spacing had the highest values in the chemical attributes beneficial to the soil at most depths in relation to at least one of the other two spacings studied, and lower values for Al, making this spacing the most suitable for recovering degraded areas/soils.
不同林种的种植间距会对增加或减少土壤中的化学元素含量产生不同的作用，从而影响土壤的成分和质量。为特定林种确定适当的种植间距非常重要，不仅能优化生产力，还能为退化土壤的恢复提供决策依据。这项工作的目的是评估以不同间距种植 Tachigali vulgaris（约七年半树龄）的土壤在化学特性方面发生的变化。这项工作在 Dom Eliseu（宾夕法尼亚州）市的 Fazenda Gênesis 进行。在 30 米 x 50 米的地块中，在四个深度采集了土壤样本，每个间距有四个重复。每个小区随机选取 16 个土壤采集点。土壤样本被送往 Embrapa Amazônia Oriental 实验室进行化学分析。PCA 结果显示，在所有深度，铝与其他土壤属性呈负相关。双向方差分析图（p < 0.05）表明，4 米 x 3 米的间距在大多数深度上对土壤有益的化学属性值最高，与其他两种间距中的至少一种相比，铝的值较低，因此这种间距最适合恢复退化的地区/土壤。

Eucalypts are a long-cycle crop that have been introduced in Brazil during several decades. The germplasm banks of the country make available several populations whose botanical classifications are somewhat outdated since these classifications have been subject to several modifications over the years. This study outlines a review of species with outdated classifications in the Anhembi Experimental Station of Forest Sciences (ESALQ/USP), one of Brazil’s main eucalypt germplasm banks and discusses the possible implications for the breeding programs that use said germplasm. In this survey, we found records that indicate introductions were made of populations of 20 eucalypts species. However, this number has increased according to the most recent update of botanical classifications, and the Anhembi Germplasm Bank has currently 22 species after a few species were reclassified. Furthermore, a major change has been the reclassification of some species from the genus Eucalyptus to the genus Corymbia. One original introduction, Eucalyptus maculata, is now considered to be (according to original provenances), Corymbia maculata and C. variegata . One species originally introduced as E. pellita has been renamed E. scias ; E. pellita still exists in north Queensland, Australia and Papua New Guinea, while E. scias has a much smaller southerly distribution in New South Wales, Australia. Similarly, an introduction of E. phaeotricha is now generally considered to be E. tindaliae, and an introduction of E. resinifera is now considered to be E. macta (according to the provenance area of the introduction). The confusing classification of the species is aggravated, in some cases, by the lack of detailed studies that allow comparing the species introduced with the same name, regarding wood productivity, tolerance and/or traits that are fundamental for defining the species to be introduced or worked on by the breeding programs.
桉树是一种长周期作物，几十年来被引入巴西。巴西的种质库中有几个种群的植物学分类已经过时，因为这些分类多年来曾多次修改。本研究概述了巴西主要桉树种质库之一的安亨比森林科学实验站（ESALQ/USP）中分类过时的物种，并讨论了对使用这些种质的育种计划可能产生的影响。在这次调查中，我们发现有记录表明，巴西引进了 20 个桉树品种的种群。不过，根据最新更新的植物学分类，这一数字已经增加，安亨比种质库在对几个物种进行重新分类后，目前有 22 个物种。此外，一个重大变化是将一些物种从桉树属重新分类为伞形科。一个最初引入的物种，即 Eucalyptus maculata，现在被认为是（根据最初的产地）Corymbia maculata 和 C. variegata。E. pellita，而 E. scias 在澳大利亚新南威尔士州的南部分布较少。同样，引进的 E. phaeotricha 现在一般被认为是 E. tindaliae，而引进的 E. resinifera 现在被认为是 E. macta（根据引进的原产地）。在某些情况下，由于缺乏详细的研究，无法对引进的同名物种进行木材生产力、耐受性和/或性状方面的比较，从而加剧了物种分类的混乱。

Sumauma ( Ceiba pentandra ) is a fast-growing and light-demanding species that occurs across a wide rainfall range in tropical regions, but it is still unclear how it performs under shading. This work aimed to evaluate leaf traits and biomass allocation of sumauma seedlings in response to different levels of artificial shadings. After a strengthening period of 14 months (at moderate light), the seedlings were submitted to three shading levels for 580 days: moderate shading (T 1 : irradiance of 5.59 mol m ‒ 2 day ‒ 1 ), strong shading (T 2 : 1.29 mol m ‒ 2 day ‒ 1 ), and deep shading (T 3 : 0.14 mol m ‒ 2 day ‒ 1 ). The control (T 0 ) was seedlings under direct sunlight (15.65 mol m –2 day –1 ). Parameters evaluated were plant growth, biomass allocation to plant organs and leaf traits. Growth and biomass accumulation enhanced with a rise in irradiance, being maximum under direct sunlight and null under deep shading. Sumauma did not succumb under deep shading, as it was able to endure deep shading for 19 months. Under deep shading, the seedlings allocated just a little amount of biomass to leaves and greatly reduced leaf thickness. The whole-plant compensation point was estimated to be 1.0 mol m ‒ 2 day ‒ 1 . We concluded that pre-strengthened sumauma seedlings may endure deep shading. These traits combined with the high growth rates of this tree under full sunlight make of sumauma a promising candidate to be tested in reforestation projects.
