Abstract

It takes Zizyphus jujuba 'Zhanshanpinguozao' as the test material. Changes of Ascorbic Acid content in four stages (young leaves, spreading leaves, mature leaves, senescent leaves) of jujube leaf development, jujube flowers and five periods of fruit development (Young fruit period, green mature period, white mature period, pre-mature period, mature period) were studied. The results showed that the change trends of AsA content in jujube leaves were similar at different stages, which showed that young leaves > spreading leaves > matured leaves > senescent leaves, and DHA content > AsA content after July 14th. While in jujube fruit, AsA content followed the fruit development, which performed first increased and then decreased, and the white mature period was the highest, and the AsA content was always higher than the DHA content. In the same period, the AsA content in the jujube fruit was greater than that of the leaf and the flower of jujube. Therefore, the accumulation rules of Ascorbic Acid in the fruits and leaves of Zizyphus jujuba 'Zhanshanpinguozao' were quite different, and the main forms of Ascorbic Acid in different tissues were different.
