Abstract

The invention discloses a tissue culture medium for phalaenopsis. The culture medium comprises an induction culture medium, a proliferation culture medium, a seedling strengthening culture medium and a rooting culture medium, the invention relates to a tissue culture propagation method of phalaenopsis amabilis, which comprises the following steps: 1) material disinfection, 2) explant inoculation, 3) propagation culture of tissue culture seedlings, 4) strong seedling culture, 5) rooting culture, 6) acclimatization and domestication, and 7) transplanting. The method has the advantages that the multiplication culture period is short, the propagation coefficient is high, the transplanting survival rate can reach 99% or above, and the method can efficiently and rapidly provide high-quality phalaenopsis seedlings. By the adoption of the method, a large number of seedlings capable of being planted out of bottles can be obtained, the method is not affected by factors such as seasons, high-quality phalaenopsis seedlings can be efficiently and rapidly provided, and the good variety popularization speed can be increased.

Description

technical field [0001] The invention relates to the technical field of plant tissue culture, in particular to a tissue culture medium of Phalaenopsis and a propagation method thereof. Background technique [0002] Phalaenopsis [phalaenopsis] is a plant of the genus Phalaenopsis in the family Orchidaceae. It is a tropical aerial orchid, commonly known as "ocean orchid". Phalaenopsis is butterfly-like in shape, beautiful in shape, rich in color and long in flowering period. It is known as the "Queen of Orchids" among tropical orchids. Phalaenopsis is rich in species and widely distributed, from the Philippines and New Guinea in the east to northern Australia in the south, Sumatra in the west, and Taiwan, Yunnan, and western Sichuan in the north. There are original species (wild Phalaenopsis> exist, about 50 kinds, Among them, there are 7 species in my country, all of which are epiphytic orchids. The large-scale commercial cultivation of Phalaenopsis is very successful, and ...
