Abstract

The invention discloses a culture medium for persimmon tree tissue culture. The culture medium comprises a subculture medium and a rooting medium. By adding defined amount of longan juice in the processes of multiplication and rooting culture, the growing of adventitious buds of a persimmon tree can be promoted, the propagation coefficient is high, at the meantime of the multiplication, the rooting is inducted, and the cultivation period is shortened. The rooting percentage and transplanting survival rate are high, and the hereditary stability is good.

Description

technical field [0001] The invention relates to a tissue culture medium, in particular to a persimmon tissue culture medium. Background technique [0002] Persimmon is a temperate deciduous fruit tree of Persimmonaceae berry class. It is native to my country and has a planting history of more than one thousand years in my country. At present, my country has the largest planting area and the largest persimmon fruit output. Persimmons are tender and juicy, sweet and refreshing, and rich in nutrition. There are two kinds of sweet persimmons and astringent persimmons. Astringent persimmons cannot be eaten directly and need to be de-astringent. Sweet persimmons can be eaten fresh. Persimmon is very rich in nutrients, rich in sucrose, glucose, fructose, protein, carotene, vitamin C, citrulline, iodine, calcium, phosphorus, and iron. Fresh persimmon contains high iodine, which can prevent endemic goiter. Persimmon is cold in nature, sweet and astringent in taste, and belongs to...
