Resumo: | The algaroba (Prosopis juliflora (Sw) D.C.) is an exotic species whose leaves have great potential for use in human and animal feeding, being highly nutritious, besides being considered efficient in the recovery of degraded areas and impoverished soils. Despite the growing demand for seeds and seedlings of this species, little is known about the physiological quality of their seeds. Therefore, the objective of this work was to characterize the fruit and seed biometry of the species, as well as to determine the temperatures and substrates for the germination and early development of seedlings. The number of seeds per kilogram and the water content of the seeds were determined. The length, diameter, weight, and number of seeds in each fruit and the thickness, width, length and weight of the seeds were analyzed. In the germination test, three temperatures (20, 30 and 20-30 °C) were used under the regime of 14 hours of white light and two substrates (on paper and paper roll). Seed embedding curves, germination, germination speed index, shoot length, root length and seedling dry mass were determined. The biometric data indicate wide variability for the characteristics evaluated for fruits, however, the seeds present less variability. Temperatures of 30 and 20-30 °C and both substrates tested are efficient for conducting the germination test of algaroba seeds in the laboratory. |

Apesar da procura crescente por sementes e mudas desta espécie, pouco se conhece sobre a qualidade fisiológica de suas sementes. Diante disto, o objetivo deste trabalho foi caracterizar a biometria de frutos e sementes da espécie, além de determinar as temperaturas e substratos para a germinação e desenvolvimento inicial de plântulas. Foi determinada a quantidade de sementes por quilograma e o teor de água das sementes. Analisou-se o comprimento, o diâmetro, o peso, e o número de sementes em cada fruto e a espessura, a largura, o comprimento e o peso das sementes. No teste de germinação foram utilizadas três temperaturas (20, 30 e 20-30°C) sob o regime de 14 horas de luz branca e dois substratos (sobre papel e rolo de papel). Determinaram-se as curvas de embebição das sementes, a germinação, o índice de velocidade de germinação, o comprimento da parte aérea, o comprimento da raiz e a massa seca das plântulas. Os dados biométricos indicam ampla variabilidade para as características avaliadas para frutos, entretanto, as sementes apresentam menor variabilidade. As temperaturas de 30 e 20-30°C e ambos os substratos testados são eficientes para a condução do teste de germinação de sementes de algaroba em laboratório.Universidade Federal de Santa Maria2018-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3337910.5902/1980509833379Ciência Florestal; Vol. 28 No. 3 (2018); 1271-1281Ciência Florestal; v. 28 n. 3 (2018); 1271-12811980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/33379/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessPereira, Marcio DiasRomeiro, Taline Cristina Oliveira da SilvaFlores, Andressa VasconcelosSeveriano, Rogério Luciano2018-10-08T13:21:33Zoai:ojs.pkp.sfu.ca:article/33379Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-10-08T13:21:33Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
