Oranges for Southern Arizona

Abstract

Sweet oranges (Citrus x sinensis (L.) Osbeck) (Fig. 1) are the most popular citrus variety in the world and are mainly commercially harvested for juice – 75% − rather than for fresh eating − 25%. There is nothing quite like peeling and eating a fruit from one’s own orange tree on a cool winter morning in the desert or enjoying a fresh- squeezed glass of orange juice that is far better than anything one can purchase at the supermarket. Sour oranges (Citrus x aurantium) and their subspecies are most often used as ornamental trees since their fruit are not often eaten fresh due to extreme bitterness. Sour orange oil is found in perfume and its peel is the preferred ingredient in marmalade. Whether you prefer sweet oranges or sour ones, choosing the proper variety is the most important first step.
