Light regime and temperature on seed germination in Salvia hispanica L. Agronomy
Paiva, Emanoela Pereira de; Torres, Salvador Barros; Sá, Francisco Vanies da Silva; Nogueira, Narjara Walessa; Freitas, Rômulo Magno Oliveira de; Leite, Moadir de Sousa.
This study evaluated the effects of different light regimes and temperatures on the germination of S. hispanica seeds and used a factorial scheme in a completely randomized experimental design, in which three light conditions were combined with six temperatures (constant 20, 25, 30 and 35°C and alternating 20-30 and 25-30°C), totaling 18 treatments with four 50-seed replications. The seeds were sown on blotting paper in transparent plastic boxes and then allowed to germinate in Biochemical Oxygen Demand germinators. The seeds were evaluated over a period of eight days with respect to the following variables: germination percentage, average germination time, shoot and root lengths, shoot and root dry weights and root-shoot ratio. The data were submitted to...

Different water volumes in the substrate and temperatures for germination of cabacinha seeds Horticultura Brasileira
Araújo,Paulo C; Alves,Edna U; Ursulino,Marina M; Araújo,Luciana R; Silva,Rosemere S.
Cabacinha (Luffa operculata) is a species that has been used empirically in folk medicine against sinusitis. The fruits have important pharmaceutical substances and studies related to its germination are not available, justifying the determination of the appropriate conditions that make possible the germination of its seeds. Thus, we evaluated the influence of different volumes of water in substrate and temperatures on germination and vigor of cabacinha. The treatments consisted of moistened substrate with water volumes equal to 2.0; 2.5; 3.0 and 3.5 times its weight of the dry paper and the seeds were kept in germination regulated at constant temperatures of 25, 30 and 35°C and 20-30°C alternating. The percentage and speed of germination, hypocotyl and...
