The Asian citrus psyllid has also been intercepted coming into California in packages of fruit and plants, including citrus, ornamentals, herbs and bouquets of cut flowers, shipped from other states and countries.

In some cases the parental species that gave rise to a hybrid have yet to be determined, while genotyping reveals some hybrids to descend from three or more ancestral species.

The trifoliate orange is a cold hardy plant distinguishable by its compound leaves with three leaflets and its deciduous nature, but is close enough to the genus Citrus to be used as a rootstock.
The colourful outer skin of some citrus fruits, known as zestis used as a flavouring in cooking; the white inner portion of the peel, the pith, is usually avoided due to its bitterness. At any age citrus grows well enough with infrequent irrigation in partial shade, but the fruit crop is smaller.

Compared to many of the usual “green shrubs”, citrus trees better tolerate poor container care. Subsequent study of the many commercial citrus lineages revealed such complexity that the genera could not be separated,  and genomic analysis rooted Fortunella within the polyphyletic tree of Citrricos.

Portanto, plantas tetraploides apresentam menor tamanho, crescimento em altura mais lento e citriicos mais largas e compridas. This is done not only for the useful characteristics of the fruit, but also for plant size and growth characteristics such as cold-tolerance. Being of tropical and sub-tropical origin, oranges, like all citrus, are broadleaved and evergreen. The aim of plant breeding of hybrids is to use two or more different citrus varieties or species, in order to get traits intermediate between those of the parents, or to transfer individual desirable traits of one parent into apomixis en citricos other.

This may be due to perceived similarities in the smell of citrus leaves and fruit with that of cedar.
Facultative apomixis, spontaneous polyploidization and inbreeding in Citrus volkameriana seedlings. All characterized varieties commercially called mandarins are actually hybrids.
Therefore, this may be the factor responsible for a more intense coloring observed in the tetraploid plant leaves in this study Table 2.
