“…The doses of Cu applied to the soil induced a linear reduction in the height of seedlings without inoculation, while the inoculated treatments were significantly higher with the UFSC-PT116 isolate, promoting a linear increase, being 58% higher than the control at the dose of 400 mg kg -1 (Figure 2A). These results corroborate the results obtained by Dellai et al (2018), in which Eucalyptus saligna Sm. produced in soil contaminated with Cu showed greater height when inoculated with the UFSC-PT116 isolate.…”

Copper (Cu) is one of the main heavy metals contaminating the soil. Plants have different behavior in terms of tolerance and toxicity to metals, being able to grow and produce even in soils contaminated with high concentrations. This study aimed to determine the influence of ectomycorrhizal fungi on the growth and tolerance of yerba mate plants grown in soil contaminated with Cu. The design was completely randomized in a factorial arrangement (4x6), with four possibilities of inoculum: without inoculum (control) and three ectomycorrhizal fungi (UFSC-PT116 — Pisolithus microcarpus, UFSC-PT132 — Pisolithus tinctorius and UFSC-SU118 — Suillus cothurnatus), with six Cu doses amended to the soil (0, 80, 160, 240, 320 and 400 mg kg-1 of Cu) in seven replicates. The height of the aerial part, the diameter of the lap, the dry mass of the aerial part and root system, the leaf area, the specific surface area of the roots, the contents of Cu in the aerial and radicular parts, the tolerance index, and mycorrhizal association were assessed. Inoculation of Ilex paraguariensis seedlings with ectomycorrhiza fungi UFSC-PT116, UFSC-PT132, and UFSC-SU118 mitigates the toxicity effect caused by the excess of Cu in the soil. The UFSC-PT116 isolate promoted the highest growth and tolerance of Ilex paraguariensis seedlings under the treatments. In general, the isolates promoted the reduction of Cu toxicity in Ilex paraguariensis plants, being an important alternative to remediate Cu-contaminated areas.

“…Observou-se redução na altura (cm) e no diâmetro (mm) do caule das plantas de Ilex paraguariensis, respectivamente, de 46,5 e 16,7% na maior dose de Cobre em relação à dose zero (sem adição de cobre), (Figuras 1A e 1B). Estudos com espécies arbóreas também comprovam a diminuição da altura e do diâmetro do caule em função do aumento das doses de Cu (DELLAI et al, 2018;DE MARCO et al, 2017;SILVA et al, 2014). O excesso de Cu pode causar distúrbios no crescimento e desenvolvimento normal das plantas, afetando negativamente importantes processos fisiológicos e bioquímicos, como a permeabilidade da membrana plasmática, a síntese de proteínas, a estrutura da cromatina, a atividade de enzimas nos processos de fotossíntese e respiração (AMBROSINI et al, 2016;YRUELA, 2009).…”

Crescimento e tolerância de mudas de <i>Ilex paraguariensis</i> A.St.-Hil. cultivadas em solo contaminado com cobre

et al. 2022

O cobre (Cu) é um micronutriente necessário ao desenvolvimento das plantas, pois está incluído na estrutura de compostos enzimáticos e ativadores. Contudo, em altas concentrações no solo pode se tornar tóxico ao metabolismo vegetal. Dessa forma, o objetivo deste trabalho foi avaliar o crescimento e tolerância de mudas de Ilex paraguariensis cultivadas em solo contaminado com cobre. O estudo foi conduzido em casa de vegetação do Departamento de Engenharia Florestal, Universidade Federal de Santa Maria, Campus de Frederico Westphalen, RS, entre os meses de março e setembro de 2018. As mudas de Ilex paraguariensis utilizadas no experimento foram adquiridas de um viveiro localizado no município de Arvorezinha, RS. Os tratamentos aplicados foram cinco doses de Cu (0 - controle, sem adição de cobre; 100; 200; 300 e 400 mg Kg-1 de solo). O experimento foi implantado em delineamento inteiramente casualizado com 10 repetições, sendo cada repetição uma planta por vaso. Após a exposição aos diferentes tratamentos, sob cultivo em solo aos 150 dias, avaliou-se a altura de planta, diâmetro do caule, área foliar, massa seca de raiz, caule e folhas e índice de tolerância. Os resultados evidenciaram que as doses de cobre reduziram a altura e diâmetro de caule das mudas. A massa seca de todas as partições coletadas mostrou redução a partir da utilização de 200 mg kg-1 de solo. As plantas submetidas a maior dose de Cu (400 mg kg-1 de solo) apresentaram redução na área foliar de 64,7% em relação à testemunha. A espécie Ilex paraguariensis apresentou o índice de tolerância superior a 60% até a dose de 300 mg kg-1 de Cu.

Plant quality and survival prediction tools are useful when applied in the field in different agricultural sectors. The objectives of this study were to conduct a review and bibliometric analysis of the Dickson Quality Index (DQI) as a key plant quality indicator and with respect to its scientific applications. A third objective was to identify the main morphological and physiological parameters used in plant production research. The methodology and findings of 289 scientific articles were analysed based on the morphological, physiological, and mathematical parameters used as plant quality indicators in research on forest, medicinal, horticultural, aromatic, and ornamental species. During the last 10 years, the number of publications that have used the DQI as a plant quality parameter has increased by 150%, and Brazilian researchers stand out as the most frequent users. Forestry is the discipline where quality parameters and their biometric relationships are most often used to facilitate intensive plant production. Use of the DQI increases the certainty of prediction, selection, and productivity in the plant production chain. The DQI is a robust tool with scientific application and great potential for use in the preselection of plants with high quality standards among a wide range of plant species.
