Resumo
O canistel é uma fruteira originada no México e América Central, sendo introduzida no Brasil em 1986. As plantas apresentam porte médio, porém podem atingir até 15 metros de altura; as folhas medem cerca de 10 a 25 cm; as flores são completas e pequenas, e o fruto apresenta coloração amarela quando maduro, com polpa esbranquiçada e sabor doce. A propagação pode ser realizada por semente ou por enxertia. em vista da quase total ausência de informações sobre a cultura e a possibilidade de cultivo comercial, realizou-se o presente trabalho, no qual se avaliou o efeito da temperatura na porcentagem de germinação de sementes. Foi verificado que as melhores taxas foram obtidas à temperatura de 30ºC e as menores a 15ºC, 20ºC e 40ºC, sendo esta última a pior delas.

The plants present medium size, however it can reach up to 15 meters of height; the leaves measure about 10 to 25 cm; the flowers are complete and small and the fruit presents yellow coloration when ripe, with whitish pulp and sweet flavor. The propagation can be realized by seed or grafting. In view of almost total absence of information about the culture and the possibility to have a commercial cultivation, the present work, was live in which the effect of the temperature was evaluated in the percentage of germination of the seeds. It was checked that the best averages were obtained in temperature of 30ºC and the minor in 15ºC, 20ºC and 40ºC could be considerate the worst of them.
