well, lets see...
The apple, Pyrus malus, also known as Malus pumila and Malus domestica, was probably first eaten, and later cultivated before the dawn of history in central asia, possibly Kazakhstan. It is a member of the rose family, Rosaceae, which includes blackberries, hawthorns, cinquefoils, strawberries, plums, cherries, and of course, roses. Most of the Rosaceae have showy flowers, and fruiting is benefited by cross pollination by insects, especially bees.
While oranges, (Citrus sinensis Osbeck) with numerous cultivated varieties, constitutes one of the world's most popular and recognizable fruit crops. These fruits are hesperidiums, because of their fleshiness and separable rind. Physically, citrus fruits consist of forty to fifty percent juice, twenty to forty percent rind and twenty to thirty-five percent pulp and seeds. Chemically, they contain eighty-six to ninety-two percent water, five to eight percent sugars and one to two percent pectin with lesser amounts of acids, protein, essential oils and minerals (Janick et. al. 1981).
Citrus fruits grow on small evergreen trees, many of which depend on root mycorrhizae (Janick et. al. 1981). Most of these C3 plants are cultivated as scions on rootstocks. All Citrus species have a diploid chromosome number of eighteen and are interfertile.
There; I knew I could compare them.
