Resumo: | The treatment of seeds using growth regulators can overcome seed dormancy and increase the emergence and development of seedlings. The objective of this research was to evaluate the effect of different concentrations of GA4+7 + N-(phenyl methyl)-aminopurine on the dormancy breaking of Passiflora cincinnata Mast. seeds recently harvested and stored for six years. The study was conducted in a greenhouse at Embrapa Cassava and Tropical Fruits, in completely randomized design, in a 2 x 4 factorial scheme, with the following factors: year of seed harvest (2010 and 2016) and the emergence promoter GA4+7 + N-(phenyl methyl)-aminopurine at four concentrations (0%; 0.03%; 0.45% and 0.90%), with 4 replicates of 25 seeds. Emergence percentage, first count, emergence speed index, number of leaves, root length, stem diameter, dry matter of shoots, roots and total, and root/shoot ratio were evaluated. The results showed that GA4+7 + N-(phenyl methyl)-aminopurine is recommended to overcome dormancy of Passiflora cincinnata in recently harvested seeds (2016) and increase the emergence of seedlings from seeds stored for six years in cold chamber (2010). The emergence promoter concentration of 0.03% can be used to overcome dormancy in recently harvested seeds and maintains the vigor of seeds stored for six years. Passiflora cincinnata seeds remain physiologically viable for six years and their emergence is potentiated by the use of GA4+7 + N-(phenyl methyl)-aminopurine. |

O objetivo desta pesquisa foi avaliar o efeito de diferentesconcentrações de GA4 + 7 + N- (fenilmetil) -aminopurina na quebra de dormência de sementes de Passiflora cincinnata recentemente colhidas e armazenadas por seis anos. O estudo foi conduzido em uma estufa na Embrapa Mandioca e Fruticultura, em delineamento inteiramente casualizado, em esquema fatorial 2 x 4, com os seguintes fatores: ano de colheita de sementes (2010 e 2016) e promotor de emergência GA4 + 7 + N - (fenilmetil) - aminopurina em quatro concentrações (0%; 0,03%; 0,45% e 0,90%), com 4 repetições de 25 sementes. Foram avaliados a porcentagem de emergência, a primeira contagem, o índice de velocidade de emergência, o número de folhas, o comprimento da raiz, o diâmetro do caule, a matéria seca da parte aérea, das raízes, total e a relação raiz/parte aérea. O GA4 + 7 + N - (fenilmetil) - aminopurina é recomendado para superar a dormência de Passiflora cincinnata em sementes recentemente colhidas (2016) e aumenta a emergência de sementes armazenadas por seis anos em câmara fria. A concentração do promotor deemergência de 0,03% pode ser usada para superar a dormência em sementes recentemente colhidas e potencializa o vigor das sementes armazenadas durante seis anos. As sementes de Passiflora cincinnata permanecem fisiologicamente viáveis por seis anos e seu vigor é potencializado pelo uso de GA4 + 7 + N - (fenilmetil) - aminopurina.EDUFU2018-10-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3945110.14393/BJ-v34n5a2018-39451Bioscience Journal ; Vol. 34 No. 5 (2018): Sept./Oct.; 1158-1166Bioscience Journal ; v. 34 n. 5 (2018): Sept./Oct.; 1158-11661981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/39451/24203Brazil; ContemporaryCopyright (c) 2018 Regiana dos Santos Moura, Mauricio Antônio Coelho Filho, Hans Raj Gheyi, Onildo Nunes de Jesus, Lucas Kennedy Silva Lima, Tatiana Goes Junghanshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessdos Santos Moura, RegianaCoelho Filho, Mauricio AntônioGheyi, Hans Rajde Jesus, Onildo NunesSilva Lima, Lucas KennedyJunghans, Tatiana Goes2022-02-09T11:36:27Zoai:ojs.www.seer.ufu.br:article/39451Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-09T11:36:27Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
