Abstract: The experiment was conducted on Zhanhua jujube to study the changes of ZR, iPA and few nitrogen index during the development of flower and fruit. The result showed that ZR and iPA played an important role before blossom which advanced the build up of flower organs. The fruit development of Zhanhua jujube showed a trend of "slow-fast-slow-fast-slow" and the growth of vertical diameter was faster than transverse diameter. Nitrogen index and CTK (ZR+iPA) could be remarkably divided into three stage in the period of flower and fruit development. The level of these nitrogen index increased at first and reached a high peak from the floral bud appearing to petal flatting. Second, From petal flatting to 45 days after flowering, these index decreased gradually. Three, These nitrogen index had a slight increase before maturation and CTK (ZR+iPA) appeared a peak then decreased gradually.

Key words: Winter jujube, Flower, Fruit development, CTK, Nitrogen index
