Collection of scions for grafting

For the scion used for branch grafting, the one-year-old full jujube head is the best, which grows vigorously after grafting. When the number of jujube head is insufficient, 2-3-year-old secondary branches can also be used. The quality of the scion can be distinguished by the color of the pulp, green is the best, white is the second, and yellow is not easy to survive. When budding, it is appropriate to use the jujube head of the same year to take the bud.
