A kind of rapid propagation method of blue fruit tree

Abstract

The invention discloses a rapid propagation method of blue fruit trees, which comprises the following steps: a. explant inoculation; b. proliferation cultivation; c. root induction; d. seedling hardening and transplanting. The method of the invention is beneficial to preserve provenance and variation, and maintains the excellent character of the blue fruit tree and the consistency of seedlings. It has the advantages of rapid and large-scale propagation of superior varieties. The method of the invention can produce uniform blue fruit seedlings in large quantities within 6-7 months.

Description

technical field [0001] The invention relates to tree seedling cultivation and afforestation techniques, in particular to a method for tissue culture and asexual propagation of blue fruit trees. Background technique [0002] Nyssa sinensis (Nyssa sinensis), also known as purple tree, is a tall deciduous tree belonging to the genus Nyssa sinensis. It is named for its dark blue skin when the drupe is ripe. Blue fruit tree likes light and acidic soil, and has strong adaptability. The trunk is straight, the branches and leaves are dense, the leaves are broad and gorgeous, and the ripe fruit is beautiful dark blue. It is an excellent tree species integrating ornamental and practical. The propagation method of this nursery stock is mainly seed propagation at present.
