Resumo: | Due to the tomato growing socioeconomic importance, issues about the germination and the vegetative growth of the species are the aim of studies focusing on its improvement, seeking mostly to increase productivity. Therefore, this work aimed to evaluate the influence of the gibberellic acid and different levels of shading in the germination and initial development of tomato seedlings from the Super Marmande variety. The experimental outline adopted was in randomized blocks, arranged in factorial scheme (2x3), managing the factor A with and without the application of the hormone, Gibberellin (GA), at a concentration of 200 mg.L-1, and the factor B in three different levels of luminous intensity (full sun (0%), 70 and 90% shading). The germination and the conduction of the experiment were carried out in polyethylene trays with commercial substrate Terral®, composed of 20 plants with 10 repetitions each and the evaluations were carried out 26 days after sowing (DAS). Analysis were led on germination rate, germination speed index, germination percentage, fresh mass, fresh mass, total dry biomass, root volume, stem diameter, root length, the height of aerial part and photosynthetic pigment. Results pointed out that only the levels of shading affected the germination. The application of gibberellic acid for the Super Marmande tomato did not reveal a significant effect. The development of seedlings in the shading of 70% and 90% was better when compared to the full sun treatment. |

Portanto, objetivou-se avaliar a influência do ácido giberélico e de diferentes níveis de sombreamento na germinação e no desenvolvimento inicial das mudas de tomateiro da variedade Super Marmande. O delineamento experimental foi em blocos ao acaso e os tratamentos arranjados em esquema fatorial (2x3), sendo o fator A com e sem a aplicação do hormônio, Giberelina (GA), na concentração de 200 mg.L-1, e o fator B com três diferentes níveis de intensidade luminosa (pleno sol (0%), 70 e 90% de sombreamento). A germinação e a condução do experimento foram realizadas em bandejas de polietileno com substrato comercial Terral®, composto por 20 plantas com 10 repetições cada e as avaliações foram realizadas 26 dias após a semeadura (DAS). Foram analisados taxa de germinação diária, índice de velocidade de germinação, porcentagem de germinação, massa fresca e seca da plântula inteira, volume de raiz, diâmetro do caule, comprimento de raiz e altura da parte aérea e pigmentos fotossintéticos. Os resultados demonstraram que somente os níveis de sombreamento influenciaram na germinação. Já a utilização do ácido giberélico na concentração de 200 mg.L-1, para as mudas do tomateiro Super Marmande, não apresentou efeito significativo. O desenvolvimento das mudas nos níveis de sombreamento de 70% e 90% foi melhor quando comparado com o tratamento a pleno sol.Universidade Federal de Santa Catarina2020-05-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2020.e7010210.5007/2175-7925.2020.e70102Biotemas; v. 33 n. 2 (2020); 1-82175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2020.e70102/43378Copyright (c) 2020 Ramonn Diego Barros Almeida, Cristina Moll Hüther, Ana Claudia Langaro, Nathan Pereira da Costa Correa, Julia Oliveira, Daniela Marques Correa, Jóice Azeredo Silvainfo:eu-repo/semantics/openAccessAlmeida, Ramonn Diego Barros deHüther, Cristina MollLangaro, Ana ClaudiaCorrea, Nathan Pereira da CostaOliveira, JuliaCorrea, Daniela MarquesAzevedo, Jóice2020-05-25T16:46:14Zoai:periodicos.ufsc.br:article/70102Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2020-05-25T16:46:14Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
