Abstract

In riparian areas severely affected by the rupture of iron ore dams, the effective development of arboreal individuals remains elusive. In this study, we aimed to evaluate the growth and development of Richeria grandis Vahl. (Phyllanthaceae) seedlings, when subjected to iron ore tailings (in natura) (RMF) or subsoil (TS) from natural soils in the research region. The experiment used a completely randomized design and was conducted in a nursery in a region of rustification. Survival (%), height, diameter of the root collar, leaf number, and total chlorophyll were evaluated monthly. Substrate samples were collected at the beginning and end of the experiment to carry out chemical and particle size analyses in the laboratory. Subsequently, fully expanded leaves were collected from the seedlings for the extraction and quantification of their phytolite content. Their morphotypes were quantified, registered using microphotographs, identified, and classified according to their morphological characteristics, following the International Phytolith Nomenclature Code. After 12 months of evaluation, all R. grandis seedlings had survived and showed improved growth in height and number of leaves in RMF. R. grandis is an abundant producer of phytoliths and is characterized by the multiplicity of morphotypes in its leaves.

是否有可能在铁矿尾矿中生长一种典型的河岸物种？

在受铁矿坝溃决严重影响的河岸地区，林木个体的有效发育仍是一个难题。本研究旨在对大richheria grandis Vahl的生长发育进行评价。（Phyllanthaceae）幼苗在受到研究区域自然土壤中的铁矿尾矿（RMF）或底土（TS）的影响时。试验采用完全随机设计，在锈病地区的苗圃进行。存活率（%）、根颈高度、根颈直径、叶片数和总叶绿素每月进行一次评估。在实验开始和结束时收集底物样品，在实验室进行化学和粒度分析。随后，从幼苗上收集完全展开的叶片，提取并定量其植石含量。它们的形态被量化，使用显微照片登记，根据它们的形态特征识别和分类，遵循国际植物岩命名规则。经过12个月的评估，所有的大白杨幼苗都成活，并且在RMF中表现出高度和叶片数量的提高。大黄是植物岩的丰富生产者，其叶片具有多种形态。

期刊介绍： Ecological engineering has been defined as the design of ecosystems for the mutual benefit of humans and nature. The journal is meant for ecologists who, because of their research interests or occupation, are involved in designing, monitoring, or restoring ecosystems, and can serve as a bridge between ecologists and engineers. Specific topics covered in the journal include: habitat reconstruction; ecotechnology; synthetic ecology; bioengineering; restoration ecology; ecology conservation; ecosystem rehabilitation; stream and river restoration; reclamation ecology; non-renewable resource conservation. Descriptions of specific applications of ecological engineering are acceptable only when situated within context of adding novelty to current research and emphasizing ecosystem restoration. We do not accept purely descriptive reports on ecosystem structures (such as vegetation surveys), purely physical assessment of materials that can be used for ecological restoration, small-model studies carried out in the laboratory or greenhouse with artificial (waste)water or crop studies, or case studies on conventional wastewater treatment and eutrophication that do not offer an ecosystem restoration approach within the paper.
