Resumo: | Rare earth elements, or lanthanides, are important for plant growth and can benefit seeds vigor and germination, when incorporated to the seeds treatment. Thus, this study aimed at evaluating the initial performance of lettuce seeds submitted to treatments with cerium (Ce) and lanthanum (La), as well as their absorption. For this, lettuce seeds (Regina cultivar) were immersed in aqueous solutions of Ce or La, in different experiments, at the Ce concentrations of 0.0 mg L-1, 5.0 mg L-1, 10.0 mg L-1, 15.0 mg L-1, 20.0 mg L-1 and 25.0 mg L-1, and at the La concentrations of 0.0 mg L-1, 2.0 mg L-1, 6.0 mg L-1, 12.0 mg L-1, 20.0 mg L-1 and 30.0 mg L-1, for one hour. Tests for germination, first germination count, seedling dry weight and total, root and shoot lengths were carried out. The amount of Ce and La absorbed by seeds and seedlings were also evaluated. It was concluded that the treatment of seeds with Ce and La did not increase seeds germination, but stimulated seedlings growth. When these elements are applied to lettuce seeds as aqueous solution, they are absorbed by seeds and transferred to seedlings. |

Deste modo, este trabalho objetivou avaliar o desempenho inicial de sementes de alface submetidas ao tratamento com cério (Ce) e lantânio (La), bem como a absorção destes nutrientes. Para tal, sementes de alface (cultivar Regina) foram imersas em solução aquosa de Ce ou La, em experimentos distintos, nas concentrações de Ce de 0,0 mg L-1; 5,0 mg L-1; 10,0 mg L-1; 15,0 mg L-1; 20,0 mg L-1; e 25,0 mg L-1; e nas concentrações de La de 0,0 mg L-1; 2,0 mg L-1; 6,0 mg L-1; 12,0 mg L-1; 20,0 mg L-1; e 30,0 mg L-1, por uma hora. Foram realizados testes de germinação, primeira contagem da germinação, massa seca de plântulas e comprimentos total, da raiz e da parte aérea. Além disto, determinou-se a quantidade de Ce e La absorvida pelas sementes e plântulas. Concluiu-se que o tratamento de sementes com cério e lantânio não proporcionou aumento na germinação de sementes, porém, estimulou o crescimento de plântulas. Quando estes elementos são aplicados em sementes de alface, na forma de solução aquosa, são absorvidos pelas sementes e translocados para as plântulas.Escola de Agronomia - Universidade Federal de Goiás2013-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufg.br/pat/article/view/20847Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 43, n. 1, Jan./Mar. 2013; 104-109Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 43, n. 1, jan./mar. 2013; 104-109Pesquisa Agropecuária Tropical; v. 43, n. 1, jan./mar. 2013; 104-1091983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/20847/13906Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessBarbieri, Ana Paula PiccininEspíndola, Maria Carolina GrigolettoMenezes, Nilson Lemos deHenrique, Daniela Florinda Soares2020-07-10T12:10:49Zoai:ojs.revistas.ufg.br:article/20847Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:58.514046Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
