Resumo: | African mahogany (Khaya grandifoliola) is a tree species that has gained space in the forestry market, presenting utility in a wide range of uses, especially in Brazilian territory, where it is the main substitute for Brazilian mahogany wood. The objective of this work was to perform a path analysis between the response of nutrient solution to cadmium treatment and the other variables and attributes studied: amino acid, nitrate, protein, ammonium, reductase, IDM, cadmium. The experiment was carried out in a greenhouse. At first, seedlings were habituated to be later taken to the treatment, where the applicability was given by cadmium chloride monohydrate (CdCl 2.H2O) according to the nutrient solution. The experimental design was completely randomized (DIC), mixed in five concentrations (0; 10; 20; 30 and 40 mg L-1) with seven replications, totaling 35 experimental units. To perform the comparative examination, the data were exposed to the analysis of variance, followed by regression analysis. The path analysis allowed to directly verify that increasing doses of treatment with Cadmium (CAR) reflected in a negative correlation with the amino acid content (AAR) in the roots of mahogany plants. Abiotic stress, which was exposure to a toxic chemical (cadmium), decreased, in this case, the ability of plants to synthesize amino acids. Increasing doses of cadmium treatment (CAL) reflected in negative correlation with the protein content in the leaf (PRL) of mahogany plants. Evidently, the higher the cadmium concentration, the greater the damage to mahogany's metabolic systems. With this study, we showed that excess cadmium in the soil affects the development of seedlings of forest species such as mahogany. |

O objetivo deste trabalho foi realizar uma análise de trilha entre a resposta da solução nutritiva ao tratamento com cádmio e as demais variáveis e atributos estudados: aminoácido, nitrato, proteína, amônio, redutase, IDM, cádmio. O experimento foi conduzido em casa de vegetação. A princípio, as mudas foram habituadas para posteriormente serem levadas ao tratamento, onde a aplicabilidade se deu pelo cloreto de cádmio monohidratado (CdCl 2.H2O) de acordo com a solução nutritiva. O delineamento experimental foi inteiramente casualizado (DIC), misturado em cinco concentrações (0; 10; 20; 30 e 40 mg L-1) com sete repetições, totalizando 35 unidades experimentais. Para realizar o exame comparativo, os dados foram submetidos à análise de variância, seguida de análise de regressão. A análise de trilha permitiu verificar diretamente que doses crescentes de tratamento com Cádmio (CAR) refletiram em correlação negativa com o teor de aminoácidos (TAA) nas raízes das plantas de mogno. O estresse abiótico, que foi a exposição a um produto químico tóxico (cádmio), diminuiu, neste caso, a capacidade das plantas de sintetizar aminoácidos. O aumento das doses de tratamento com cádmio (CAL) refletiu em correlação negativa com o teor de proteína na folha (PRL) das plantas de mogno. Evidentemente, quanto maior a concentração de cádmio, maiores serão os danos aos sistemas metabólicos do mogno. Com este estudo, evidenciamos que excesso de cádmio no solo afeta o desenvolvimento de mudas de espécies florestais como o mogno.Universidade Federal de Santa Maria2024-03-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/7380010.5902/1980509873800Ciência Florestal; Vol. 34 No. 1 (2024): Publicação Contínua; e73800Ciência Florestal; v. 34 n. 1 (2024): Publicação Contínua; e738001980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMenghttps://periodicos.ufsm.br/cienciaflorestal/article/view/73800/63443Copyright (c) 2024 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessMachado, Liliane CorreaPaiva, Rafael CostaSousa, Josilene do Carmo Mescouto deCosta, Thays CorreaMartins, Jéssica Taynara da SilvaNascimento, Vitor Resende doRoque, Cassiano GarciaOliveira, Job Teixeira deAmarante, Cristine Bastos doBrito, Ana Ecídia de AraújoSilva, Priscilla AndradeOliveira Neto, Cândido Ferreira de2024-03-27T16:38:37Zoai:ojs.pkp.sfu.ca:article/73800Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2024-03-27T16:38:37Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
