Abstract:

In this study,by using Ziziphus jujuba‘Dongzao’as a model,the phenological phases of flower development were documented,the process of flower development and nectar secretion was tracked,and the quantity and sugar content of the nectar were assessed under the facility cultivation. The results showed that compared to the open field cultivation,facility cultivation significantly advanced the sprouting stage of jujube floral bud,extended the duration of individual flower blooming and peak flowering periods,and increased both the quantity and sugar content of nectar. Overall,under the facility cultivation,‘Dongzao’exhibited superior in phenological phases,flower development,as well as nectar composition and quantity,compared to those under the traditional open field cultivation.

Key words: jujube, facility cultivation, flower development, nectary, nectar secretion pattern, nectar composition
