The evaluations have covered morphological, agronomical, cytological, palynological, nutritional, and reproductive biological traits, as well as biotic resistance and abiotic tolerance2,35,36,37. 2009BADA4B03), by the Chinese Ministry of Agriculture (Project No. Agr. Agric. The results of sensory tests and analyses with common consumers of different ages and origins are positive and encouraging14,152. Ser. should not be planted in the shade of other trees Soils: Jujubes tolerate many types of soils, but prefer a sandy, well-drained soils and do less well in heavy, poorly drained soil. Horticultur60, 16 (2017). The images or other third party material in this article are included in the articles Creative Commons license, unless indicated otherwise in a credit line to the material. Hebei Agricultural Universtiy, Baoding (2008). In recent years, the interploidy hybridization of jujube and the interspecific hybridization between jujube and sour jujube were successfully carried out20,84,85. J. Third, jujube fruit can satisfactorily meet the various needs of marketers. In the Book of Songs, published 3000 YA, it is clearly mentioned that jujubes were already widely cultivated in China. showed that the percentage of healthy fruit and the edible rate of Dongzao jujube stored at 2C for 100 days were 7.4% and 20.2% higher than those of jujube stored at 0C125. In: Ashton MS, Montagnini F (eds) The silvicultural basis for agroforestry systems. A large number of local cultivars, such as Zanhuangdazao, Linyilizao, Dongzao, Qiyuexian, Junzao, Huizao, etc. In this agroforestry system, the jujube trees are grown simultaneously with cotton for 180-200 days. Consequently, the costs of cultivation and management for jujube are significantly lower than those for other common fruit trees. Soc. Study on cAMP in branch and leaf of Chinese jujube and seedlings of wild jujube. A study on the classification of jujube and wild jujube by peroxidase isozyme. Liu, X., Chen, L., Wang, J., Li, L. & Peng, J. BMC Genomics18, 855 (2017). & Gao, Q. At the same time, traditional sparse planting systems with large crowns (row spacing and plant height above 5m) and intercropping jujubes with cereal crops (row spacing 12m) were replaced by dense dwarf planting (2m3m) and monoculture orchards. Zhang, L. et al. This work was supported by grants from the Significant Fund of Hebei Province Natural Science Foundation (grant number C2017204114), the National Science and Technology Support Plan of China (2019YFD1001605), the National Ten Thousand Talents Plan Leadership Project, and the Beijing Municipal Education Commission (CEFF-PXM2019_014207_000099). The specific objectives should include outstanding resistance to biotic and abiotic stresses, dwarfing, low branching ability, thornlessness, early bearing, high and stable yields, high quality, stonelessness, high nutrient levels, various ripening times, ease of transport and storage, and multiple-use cultivars.
