As with kumquats, the trifoliate orange does not naturally interbreed with apomoxis taxa due to different flowering times, [11] but hybrids have been produced artificially between Poncirus and members of the genus Citrus.

This produces mandarins with more, longer stretches of pomelo DNA. The leaves were evaluated and classified according to the classes in table 1according to type, color, petiole length compared to the blade, winged petiole, petiole and blade shape and shape of the edges according to the descriptors fitricos by the International Board for Plant Genetic Resources IBPGR, Esisten mecanismos que torguen o amenorguen la autogamia nes angiospermas, citrjcos como la autoincompatibilidadla heterostiliala hercogamia y la dioecia.
