Resumo: | Aroeira has great economic importance due to its wood useful, tannins extraction and use in the pharmacology. The aim of this work was to evaluate the germination aspects and initial seedlings development of aroeira, under gibberellins, substrata and shading effects, and for that two experiments were led out. In the first one, seeds were previously soaked for 24 hours in water and in 100 mg.L-1 gibberellin solution and were sowed directly in cells trays in the following substrata: land and sand (1:1 and 1:2) and Plantmax . In the second experiment, 15 cm length seedlings were transplanted to polyethylene sacks filled out land+sand+poultry manure (1:1:1) partly decomposed and they were maintained at greenhouse for 15 days. Soon after, seedlings were transferred for the following conditions: shading (50%) and full sun and they were 50 mg.L-1 and 150 mg.L-1 gibberellins solutions pulverized, as control seedlings water pulverized. Aroeira seeds should not be previously water or gibberellins imbibed before being sowed. The best substrata for aroeira seeds germination was Plantmax without germinative treatments to reach higher than 80% of seedlings survival. The seedlings developed better at full sun light and the gibberellin. It was observed increment in height, diameter, foliar area and fresh and dry mass from aerial and root part when compared to shading situation. The gibberellins applications did not influence the aroeira seedlings initial growth characteristics. |

Neste trabalho, objetivou-se avaliar os aspectos da germinação das sementes e do desenvolvimento inicial de aroeira em função de giberelina, substrato e luz, conduzidos em dois experimentos. No primeiro, utilizaram-se sementes embebidas durante 24 horas em água e em solução de giberelina 100 mg.L-1 e sementes semeadas diretamente em bandejas de células, nos seguintes substratos: terra e areia nas proporções de 1:1 e 1:2 e Plantmax . No segundo experimento, as plântulas com 15 cm de comprimento foram transplantadas para sacos de polietileno preenchidos com terra+areia+cama de aviário semi decomposta (1:1:1) e foram mantidas em casa de vegetação durante 15 dias. Posteriormente, as mudas foram transferidas para as seguintes condições: 50% de sombreamento e pleno sol e foram pulverizadas com soluções de giberelina nas concentrações de 50 mg.L-1 e 150 mg.L-1 e apenas água para as mudas que serviram como controle. Sementes de aroeira não necessitam de pré-embebição em água ou em giberelina antes da semeadura. O melhor substrato para a germinação das sementes foi o Plantmax , sem necessidade de tratamentos pré-germinativos para obtenção de acima de 80% de sobrevivência de plântulas. As mudas desenvolvem melhor apleno sol, sendo observado incremento em altura, diâmetro, área foliar, massas fresca e seca da parte aérea e da raiz em relação ao sombreamento. A aplicação de giberelina não influenciou as características de crescimento inicial das mudas de aroeira.Universidade Federal de Lavras (UFLA)2016-04-052017-08-01T20:17:00Z2017-08-01T20:17:00Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfSCALON, S. de P.
