tedious and relatively expensive. In Florida better methods have
developed and are used commercially. Chief among these are
grafting and chip-budding, xxxx Trees of the Philippine race xxxxx
xxxxx xxxxxxxxxx almost always produce fruit exactly like
that of the parent tree, and for this reason are extensively grown
in Mexico. This race is polyembryonic, which means that trees
usually do not develop from xxxxx fertilized ovules but from what
are known as nucellar buds arising from xxxxxxx vegetative
tissues surrounding the egg cell, hence they are xxxxxxx in most
respects similar to grafted plants. Most of the East Indian
varieties, on the other hand, are monoembryonic, which means
that young trees develop only from fertilized ovules and therefore
are subject to the variation common among seedlings of cultivated
plants in general.

Except with occasional dwarf varieties such as Julie, trees
in commercial plantings are spaced xxxxxx 35 to 45 feet apart.
The mango has a number of enemies, chief among which are xxx the
anthracnose fungus, mentioned above, and xxx larvae of several
fruit flies (principally species of the genus Anastrepha in
tropical America), the larvae of which infest the fruit and render
them unfit for human consumption. A few scale insects also are
serious in certain regions.
