Resumo: | Cereus jamacaru DC. has direct use for humans in the treatment of diseases and in diet; it can also be given to animals as forage and used as adornments. Their propagation from seeds is not yet known. The experiment was conducted at the Laboratory of Seed Analysis at the Center for Agrarian Sciences of UFPB, in Areia – Paraíba State, northeastern Brazil, with the objective of verifying the effects of different temperatures and substrates on the germination and vigor of C. jamacaru seeds. The experiment was conducted in an entirely randomized design, in a 3 x 3 factorial scheme: three temperatures (25, 30 and 20-30°C) and 3 substrates (paper roll, between and on-paper), with four repetitions of 25 seeds. The employed tests were: germination, germination speed index (GSI), length and dry mass of seedlings. Germination tests were carried out using transparent plastic boxes (gerbox) in BOD chambers, set in the temperatures of 25, 30 and 20-30°C; the substrates used were paper roll, between and on-paper. Vigor was evaluated through the germination speed index (GSI), length and dry mass of seedlings. The temperature of 25°C is not adequate for germination and vigor tests. The paper roll in constant temperature of 30°C substrate proved more appropriate for conducting germination and vigor tests in seeds of C. jamacaru. |

Sua propagação por sementes ainda não é conhecida. O experimento foi realizado no Laboratório de Análises de Sementes do Centro de Ciências Agrárias da UFPB, com o objetivo de verificar os efeitos de diferentes temperaturas e substratos sobre a germinação e o vigor das sementes de C. jamacaru. O experimento foi conduzido em delineamento inteiramente casualizado, em esquema fatorial 3x3, sendo três temperaturas (25, 30 e 20-30°C) e três substratos (rolo de papel, entre e sobre papel), com quatro repetições de 25 sementes. Os testes de germinação foram realizados em caixas plásticas transparentes (gerbox) em câmeras BOD, reguladas nas temperaturas de 25, 30 e 20-30°C, e os substratos utilizados foram rolo de papel, entre e sobre papel. Os testes empregados foram: germinação, índice de velocidade de germinação (IVG), comprimento e massa seca de plântulas. A temperatura de 25°C não é adequada para os testes de germinação e vigor. O substrato rolo de papel na temperatura de 30°C mostrou-se mais adequado para condução de testes de germinação e vigor em sementes de Cereus jamacaru DC.Universidade Estadual De Maringá2009-05-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/mswordhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/63510.4025/actascibiolsci.v31i2.635Acta Scientiarum.
