| dc.description | Contextualization: Lupinus bracteolaris is a heliophite species that vegetates low lands, open slopes and sandstone hills. Knowledge gap: Despite the high rusticity and potential for covering poor soils, there is still no information to assist in the analysis of its seeds. Purpose: To determine pre-germinative treatments, substrate, temperature, luminosity and water intake in the vigor of Lupinus bracteolaris seeds. Methodology: Fruits were collected from 20 matrix plants, then the seeds were processed and submitted to the following tests: pre-germinative methods (six treatments at 25°C); substrates and temperatures (sand and paper at 20, 25 and 30°C); photoblast test (white light, diffuse-green light and continuous dark under 20°C) and the imbibition curve (control and scarification between sandpaper under 20°C). Evaluations: percentage of germination and formed seedlings, germination speed index, average germination time and seedling formation, using a completely randomized design. Results and conclusions: According to the analyzed variables, the results showed superiority for the pre-germinative treatment between sandpapers for 20 seconds. In addition, the substrate paper germibox and the temperature of 20°C were the most suitable during seed germination. The seeds of Lupinus bracteolaris were classified as neutral-photoblastic and without dormancy. | en |
| dc.description | Contextualização: Lupinus bracteolaris é uma espécie heliófita que vegeta campos baixos, taludes descobertos e morros areníticos. Lacuna de conhecimento: apesar da elevada rusticidade e potencial para cobertura de solos pobres, ainda não há informações que auxiliem na análise de suas sementes. Objetivo do estudo: determinar tratamentos pré-germinativos, substrato, temperatura, luminosidade e absorção de água no vigor de sementes de Lupinus bracteolaris. Metodologia: Coletaram-se frutos em 20 plantas matrizes, posteriormente realizou-se o beneficiamento das sementes e as submeteram aos testes: métodos pré-germinativos (seis tratamentos sob 25°C); substratos e temperaturas (areia e papel sob 20, 25 e 30°C); teste de fotoblastia (luz branca, luz verde difusa e escuro contínuo sob 20°C) e a curva de embebição (controle e escarificação entre lixas sob 20°C). Avaliações: percentual de germinação e de plântulas formadas, índice de velocidade de germinação, tempo médio de germinação e de formação de plântulas, utilizando-se delineamento inteiramente casualizado. Resultados e conclusões: De acordo com as variáveis analisadas, os resultados evidenciaram superioridade para o tratamento pré-germinativo entre lixas durante 20 segundos. Além disso, o substrato papel germibox e a temperatura de 20°C foram os mais adequados durante a germinação das sementes. As sementes de Lupinus bracteolaris foram classificadas como fotoblásticas neutras e sem dormência. | pt-BR |
