We can simulate the growth trend of the bearing jujube based on different length conditions and use L ( d) = l max 1 + e a - r d to calculate the length of the bearing jujube based on different growth days. It can be seen that jujube fruit can meet the marketers demand for profits and risk avoidance. Asian J. Chem.23, 39893992 (2011). Luo, Z. Qu, Z. Thank you for visiting nature.com. J. Hebei Agric.

With the breakthroughs in cross-breeding technology, the acquisition of a progeny population and the establishment of genetic maps, genetic research into important traits was also carried out. However, in addition to the storage conditions, the duration of fresh jujube storage and the percentage of fruit losses are also influenced by the preharvest cultivation technology and directly by the pathogen load on the fruit in the orchard14,100,113,127,128.

Dongzao. 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. On the other hand, the lignification of bearing shoots changes the deciduous habit of bearing shoots and increases the pruning labor costs. The cultivation of fresh jujubes in plastic shelters has resulted in great success in rainy southern China108; this method can greatly reduce the fruit cracking caused by rain at the maturity stage from 70 to <10%. What Makes a Root Produce a Sucker? BMC Plant Biol.19, 189 (2019). Acta Hortic. A set of new propagation approaches has been developed on the basis of traditional sucker division.

In the last 10 years, a high-efficiency hybrid breeding technology system combining male-sterile germplasm, embryo rescue, net control hybridization, and molecular identification was established. The novel field technique for homogeneous polyploidy induction has been successfully applied in sour jujube78 and in elm (data not shown).

The contents of sugar, vitamin C, and cyclic adenosine monophosphate (cAMP) are around 2, 100, and 1000 times those of apple, respectively. Since no new gene fusions or multiple trait combinations are available in autopolyploidization and it is difficult to make large breakthroughs via selection breeding, there is no substitute for cross-breeding, and its advantages are also incomparable.

The RLD of 6-year-old jujube intercropped with wheat at different soil depths was influenced by intercropping to a smaller extent than in other jujube/wheat intercropping combinations. There are many traditional processed jujube products, such as candied jujube, smoked jujube, stoneless sugared jujube, jujube liquor, liquor-saturated jujube, jujube jam, jujube paste, and so on103,148,149.
