Resumo: | Luminosity influences seed emergence in the initial development of papaya plants, being necessary the identification of the ideal irradiance level for plantule establishment and formation of vigorous seedlings. This study aimed to evaluate the seed emergence and seedlings vigor of four papaya genotypes, under different irradiance levels. Carica papaya L. seeds, from the Caliman 01 hybrid, Golden THB, triple hybrid and JS12 x Waimanalo hybrid genotypes, were evaluated under four irradiance levels (60 mmol m-2 s-1, 130 mmol m-2 s-1, 580 mmol m-2 s-1 and 1,200 mmol m-2 s-1). A completely randomized design, in a 4x4 split-plot scheme, with four replications, was used. The emergence percentage and speed index were evaluated. The seedlings were measured at 45 and 120 days after sowing (DAS), concerning root and shoot length and dry matter, being calculated the root/shoot ratio and absolute growth rate at 120 DAS. The full sun affected emergence, while the low irradiance affected seedling growth. The intermediate irradiance (130 mmol m-2 s-1 and 580 mmol m-2 s-1) was more suitable to the development of papaya seedlings up to 120 DAS. The Golden THB genotype was more sensitive to high irradiance, while the Caliman 01 and JS12 x Waimanalo hybrids tolerated the full sun condition. |

Objetivou-se estudar a emergência de sementes e o vigor das mudas de quatro genótipos de mamoeiro, em diferentes níveis de irradiância. Foram utilizadas sementes de Carica papaya L. dos genótipos híbrido Caliman 01, Golden THB, híbrido triplo e híbrido JS12 x Waimanalo, sob quatro níveis de irradiância (60 mmol m-2 s-1, 130 mmol m-2 s-1, 580 mmol m-2 s-1 e 1.200 mmol m-2 s-1). Utilizou-se delineamento inteiramente casualizado, em esquema de parcelas subdivididas 4x4, com quatro repetições. Foram avaliados a percentagem e o índice de velocidade de emergência. As mudas foram avaliadas aos 45 e 120 dias após a semeadura (DAS), quanto ao comprimento e massa seca da raiz e da parte aérea, sendo calculadas a razão raiz/parte aérea e a taxa de crescimento absoluto, aos 120 DAS. O sol pleno prejudicou a emergência, enquanto a baixa irradiância prejudicou o desenvolvimento das mudas. A irradiância intermediária (130 mmol m-2 s-1 e 580 mmol m-2 s-1) foi mais adequada ao desenvolvimento das mudas de mamoeiro, até os 120 DAS. O genótipo Golden THB foi mais sensível à elevada irradiância, enquanto os híbridos Caliman 01 e JS12 x Waimanalo toleraram a condição de sol pleno.Escola de Agronomia - Universidade Federal de Goiás2014-10-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Experimentalapplication/pdfhttps://revistas.ufg.br/pat/article/view/26429Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 44, n. 3, Jul./Sep. 2014; 325-333Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 44, n. 3, jul./set. 2014; 325-333Pesquisa Agropecuária Tropical; v. 44, n. 3, jul./set. 2014; 325-3331983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/26429/17152Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessMengarda, Liana Hilda GolinLopes, José CarlosBuffon, Rafael Breda2020-07-10T16:41:14Zoai:ojs.revistas.ufg.br:article/26429Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:04.390282Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
