BIOMETRIA DE FRUTOS E SEMENTES E TRATAMENTOS PRÉ-GERMINATIVOS EM SEMENTES DE Hymenaea courbaril

Abstract: RESUMO: A caracterização de frutos e sementes de espécies florestais é fundamental para o conhecimento das condições ideais de germinação e seu uso na revegetação de ambientes degradados. Este trabalho teve por objetivo caracterizar biometricamente frutos e sementes e definir o método adequado para superação de dormência das sementes de Hymenaea courbaril. Foram mensurados comprimento, largura, espessura e massa de frutos e sementes, sendo posteriormente, as sementes submetidas aos seguintes tratamentos pré-ge… Show more

“…A large variation in fruit size was recorded for the population of Jatobá-da-Mata, as was also seen by Pereira, Giraldelli, Laura and Souza (2011) and Santos et al (2019) in H. stigonocarpa var. stigonocarpa showing great variability in relation to fruit size, number of seeds per fruit, and seed mass.…”

“…Mechanical scarification resulted in a high percentage of emergence (treatments 1 and 3). This process allowed the entry of water and oxygen, in addition to favoring the action of hydrolytic enzymes that act with the activation of protein synthesis, enabling the mobilization of reserves from the germination process, as seen by Santos et al (2019), who obtained 93% seed germination from H. courbaril when subjected to mechanical scarification. This was also seen by other authors, such as Coelho and Ribeiro (2018), above 93%, Cabral, Castilho and Pagliarini (2015), above 86%, Sampaio et al (2015), with 84%, Souza et al (2015), above 80%, and by Silva and Cesarino (2016) with 69.2%.…”

“…Nessa perspectiva, embora a escarificação seja uma técnica mais trabalhosa e demorada, representa a opção mais prática e segura, em comparação ao uso do ácido sulfúrico. Ademais, o uso do ácido sulfúrico de maneira inadequada pode oferecer risco à saúde das pessoas que o manipulam, além de ser uma técnica que pode onerar o preço final da muda (SANTOS et al, 2019) e o risco ambiental, caso não disponha de local de descarte apropriado (DUTRA et al, 2017). O uso do ácido sulfúrico apresenta maior praticidade na escarificação de sementes para produção de mudas em larga escala (SANTOS et al, 2019), contudo, sua utilização deve ser evitada em viveiros que não apresentem estrutura adequada para a manipulação do produto (FREIRE et al, 2016).…”

“…H. Courbaril is popularly known as "jatobá, jutaí, jataí-açu, jataí-bravo, jutaí-grande, jataí-peba, jataí-uba or jatobá-do-campo". This species has aroused both economic interest in civil and naval construction, in the ornamentation of parks and gardens, in reforestation and also in medicine (Santos et al, 2019).…”
