Resumo: | The objective of this study was to identify the color of Albizia hasslerii fruit that corresponds to seeds with high physiological potential. Fruits were harvested at different ripening stages for the analysis and were visually classified into four stages according to epicarp color: 100% green (stage 1), ≤ 50% brown (stage 2), between 50% and 99.9% brown (stage 3) and 100% brown (stage 4). Subsequently, we quantified seed biometric attributes and proceeded to install the germination and vigor tests. To verify the relationship between fruit maturation with seed biometrics and the physiological potential, we calculated the Spearman correlation coefficient (ρ). The design was a completely randomized, and the results were submitted to analysis of variance with means compared by Tukey test at 5% probability. The seeds from the fruits classified as stages 3 and 4 showed greater germination and emergence, lower averages of water content and higher dry biomass, being those indicators of the best time for the fruit harvest. The seeds from green fruits presented low germination and vigor, high water content and lower dry biomass. It was concluded that seeds with high physiological potential are from fruits with 100% brown color. However, fruits showing 50% brown color can already be harvested. Therefore, fruit color is considered an indicator of physiological maturity for Albizia hassleri. |

Os frutos foram colhidos em diferentes estádios de maturação para a realização das análises, sendo classificados visualmente em quatro cores: 100% verde (estádio 1), ≤ 50% marrom (estádio 2), entre 50% e 99,9% marrom (estádio 3) e 100% marrom (estádio 4). Posteriormente, procedeu-se a mensuração dos atributos biométricos das sementes, e simultaneamente, Risssos testes de germinação e vigor foram instalados. Para verificar a relação da maturação de frutos com a biometria e o potencial fisiológico de sementes, determinou-se o coeficiente de correlação de Spearman (ρ). O delineamento utilizado foi inteiramente casualizado, sendo os resultados submetidos à análise de variância, e as médias comparadas pelo teste de Tukey, a 5% de probabilidade. As sementes provenientes dos frutos que se encontravam nos estádios 3 e 4, manifestaram maior germinação e emergência, menores médias de teor de água e maior matéria seca, sendo esses indicadores do melhor momento de colheita de frutos. Já as sementes obtidas de frutos verdes apresentaram baixa germinação e vigor, alto teor de água e menor matéria seca. Conclui-se que as sementes com alto potencial fisiológico estão em frutos com cor 100% marrom, porém a partir de 50% de cor marrom já podem ser colhidos. Portanto, a cor dos frutos é considerada um indicador de maturidade fisiológica para a espécie Albizia hasslerii.Universidade Federal de Santa Maria2020-06-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3536210.5902/1980509835362Ciência Florestal; Vol. 30 No. 2 (2020); 556-564Ciência Florestal; v. 30 n. 2 (2020); 556-5641980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/35362/35362Copyright (c) 2020 Ciência Florestalinfo:eu-repo/semantics/openAccessRistau, Ana Carolina PinguelliMalavasi, Marlene de MatosCruz, Maria Soraia FortadoVeraMalavasi, Ubirajara ControDranski, João Alexandre Lopes2021-05-20T04:00:47Zoai:ojs.pkp.sfu.ca:article/35362Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2021-05-20T04:00:47Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
