Not available – first paragraph follows: Jujube, or Chinese date, is a deciduous nit tree of tropical and subtropical origin, now grown primarily in home gardens in California and Florida. Among problems that have limited development of jujube as a commercial crop in California are several factors related to harvesting and postharvest handling. These include variation in ripening time among fruits, failure of green fruits to ripen after harvest, and poor storageability of ripe fruits on the tree. To help overcome these limitations, we conducted studies on compositional changes associated with maturation and ripening and on optimum postharvest handling temperatures for transport and storage of these fruits.
