Resumo: | The optimum temperature for germination of cacti vary with the species. With this work, we aimed to evaluate the seeds germination of pitaya genotypes under different temperatures. The used genotypes were: Hylocereus undatus (PB), H. polyrhizus (PV), Selenicereus megalanthus (PA), H. undatus x H. costaricensis (PH1) and H. costaricensis x H. undatus (PH2). For each genotype we used four replicates of 50 seeds, in a completely randomized design. The sowing was carried out on blotter paper in boxes type Gerbox ®, maintained at temperatures of 15, 20, 25, 30 and 35 oC constant and 15-25, 20-30 and 25-35 oC alternating with photoperiod 12 hours. The test lasted 30 days which were appraised the germination percentage, the germination speed index and the average time of germination. For seeds germination of PB, the result obtained in the temperature of 25 oC didn’t differ of the obtained to 30 and 20-30 oC, however it was superior to the others temperatures. In PV, the result at 25 oC didn’t differ of the obtained to 20 and 30 oC, being superior to the results of the others temperatures. For PA, the best result was obtained to 25 oC. In PH1, the temperatures of 25, 30 and 20-30 oC presented superiors results to the others. For PH2, the result obtained in 15-25oC didn’t differ of the obtained at 25 oC, however it was superior to the others temperatures. The constants temperatures of 25 and 30 °C and alternating 20-30 °C are suitable for germination of H. undatus and for the hybrid H. undatus x H. costaricensis. For H. polyrhizus, constant temperatures of 20, 25 to 30 °C are suitable for seed germination. The constant temperature of 25 °C is the most suitable for the germination of S. megalanthus. For the hybrid H. costaricensis x H. undatus, constant temperature of 25 °C and alternating 15-25°C are suitable for seed germination. |

Com esse trabalho, objetivou-se avaliar a germinação de sementes de genótipos de pitaya sob diferentes temperaturas. Os genótipos utilizados foram: Hylocereus undatus (PB), H. polyrhizus (PV), Selenicereus megalanthus (PA), H. undatus x H. costaricensis (PH1) e H. costaricensis x H. undatus (PH2). Para cada genótipo utilizou-se quatro repetições de 50 sementes, em delineamento experimental inteiramente casualizado. A semeadura foi realizada sobre papel mata-borrão, em caixas tipo Gerbox®, mantidas sob as temperaturas de 15, 20, 25, 30 e 35 oC constantes e 15-25, 20-30 e 25-35 oC alternadas, com fotoperíodo de 12 horas. O teste de germinação durou 30 dias, nos quais foram avaliados a porcentagem, o tempo médio e o índice de velocidade de germinação. Para a germinação de sementes de PB, o resultado obtido na temperatura de 25 oC não diferiu dos obtidos a 30 e 20-30 oC, no entanto foi superior às demais temperaturas. Em PV, o resultado a 25 oC não diferiu dos obtidos à 20 e 30 oC, sendo superior aos resultados das demais temperaturas. Para PA, o melhor resultado foi obtido a 25 oC. Em PH1, as temperaturas de 25, 30 e 20-30 oC apresentaram resultados superiores às demais. Para PH2, o resultado obtido em 15-25 oC não diferiu do obtido à 25 oC, no entanto foi superior aos das demais temperaturas. As temperaturas constantes de 25 e 30 ºC e a alternada de 20-30 ºC são adequadas para a germinação de sementes de H. undatus e para o híbrido H. undatus x H. costaricensis. Para H. polyrhizus, as temperaturas constantes de 20, 25 e 30 ºC são adequadas para a germinação das sementes. A temperatura constante de 25 ºC é a mais adequada para a germinação de sementes de S. megalanthus. Para o híbrido H. costaricensis x H. undatus, a temperatura constante de 25ºC e a alternada de 15-25 ºC são adequadas para a germinação das sementes.UEL2014-09-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo CientíficoArtigo Científicoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1079210.5433/1679-0359.2014v35n4Suplp2251Semina: Ciências Agrárias; Vol. 35 No. 4Supl (2014); 2251-2258Semina: Ciências Agrárias; v. 35 n. 4Supl (2014); 2251-22581679-03591676-546Xreponame:Semina.
