| Abstract:
Jujube (Ziziphus Mill.), the most important genus of family Rhamnaceae, consists of more than 170 species and distributes from the temperate to tropical regions. It is becoming increasingly popular because of its outstanding advantages including early bearing, rich in nutrition, multi-use, long flowering season, as well as high tolerance to drought and barren soils. China is one of the origin and distribution centers of Ziziphus and the only country having all the sub-genus taxa of Ziziphus. There are at least 14 species of genus Ziziphus in China, of which Chinese jujube (Z. jujuba Mill.) is the most important one, followed by Z. mauritiana Lam. (ber or Indian jujube) and Z. acidojujuba C.Y. Cheng et M.J. Liu (sour jujube or acid jujube) in terms of resource abundance and economical value. Chinese jujube is derived from sour jujube and distributed mostly in temperate zone with utilization and cultivation history over 7700 years. It has been introduced to more than 30 countries and has become commercially cultivated fruit tree in South Korea. In 2006, its total growing area in China was approximately 150 million ha with production of 3.05 million tons on a fresh weight basis, accounting for 99% of those in the world. Chinese jujube has about 750 cultivars, which are commonly grouped into table, dried, candied, multipurpose and ornamental jujube. The present status of propagation, cultural techniques, storage, as well as trade and developing trend were also briefly introduced. | |
