Fast propagation method for aquatic plant lotus flowers

Abstract

The invention relates to a fast propagation method for aquatic plant lotus flowers. According to the method, in vitro tissue culture is firstly adopted for obtaining tissue culture seedlings, and the in vitro tissue culture comprises the following steps that: (1) lotus flower seeds are used as initial raw materials, after the lotus flower seeds are subjected to sterilization and disinfection treatment, plumules are taken out under the aseptic condition and are inoculated into a basic culture medium to be cultured for 2 to 3 weeks, and aseptic seedlings are obtained; (2) the hypocotyl upper parts and cotyledons of the aseptic seedlings containing growth point parts are cut off and are inoculated into a propagation culture medium, the light illumination culture is carried out for 3 to 4 weeks, and tissue culture calluses are obtained; (3) buds with the length being 2 to 3cm in the tissue culture calluses obtained in the second step are cut off and are inoculated into a strong seedling culture medium to be cultured; and (4) after the seedlings in the third step grow to 4 to 6cm, the seedlings are transplanted onto a rooting culture medium for carrying out rooting culture, and the tissue culture seedlings are obtained. The fast propagation method provided by the invention solves the problems of few lotus root resources and long propagation period in the prior art, and a new path is provided for meeting the market requirements.

[0001] The invention relates to a rapid propagation method of aquatic plant lotus. Background technique

[0002] Lotus (Nelumbo nucifera) is a perennial aquatic perennial herb of the family Nymphaeaceae, also known as lotus, and is one of the top ten traditional famous flowers in China. The lotus varieties include about 3 strains, 6 groups, 14 categories, and 38 types, including 278 varieties, and there are more than 600 varieties of ornamental lotuses. Lotus is generally distributed in subtropical and temperate regions such as Central Asia, West Asia, North America, India, China, and Japan. my country has a long history of cultivating lotus, which was cultivated as early as more than 3,000 years ago. From Heilongjiang in the north, to Hainan in the south, from Jiangsu, Zhejiang, and Taiwan in the east, to the south of Tianshan Mountain in Xinjiang in the west, except for Tibet and Inner Mongolia, there are lotus flowers distributed in swamps, wetlands, lak...
