花卉组培（Floral tissue culture）

花卉组培（Floral tissue culture） Flower tissue culture techniques 1. The application value of flower tissue culture Tissue culture of flower, is to separate a part of flower plants, such as stems, stems, leaves, flowers, immature embryo, in sterile tubes, and with nutrition, hormones, temperature and light conditions, to produce a complete plant. Because its condition can be controlled strictly, the growth is rapid, 1-2 months is a cycle, therefore, it has important application value in the production of flowers and plants. Rapid propagation: for a few rare varieties of flowers that are difficult to reproduce and some flowers which need to be produced in a short period of time, they are widely used. Orchid, chrysanthemum, gladiolus flowers such as the use of axillary bud proliferation, short-term get a large number of plants. African violets can produce adventitious buds through leaves, daffodils, and ground scales to achieve mass reproduction. Flower Breeding: many flowers such as lily and iris can carry out distant hybridization. Because of physiological, metabolic and other reasons, hybrid embryos are often aborted early, and therefore hybrid plants can not be obtained. The embryo culture in the test tube can make it grow smoothly and get distant hybrids. In addition, a variety of methods, such as callus mutagenesis and pollen culture, can be used for flower breeding. Cultivation of virus-free seedling: chrysanthemum, gladiolus, daffodils, tulips, dahlia and a large number of flowers by asexual reproduction method virus propagation, generational transfer accumulation, serious harm. Whereas the flower plants grown at 0.1-0.5 mm in size, the growth spots were essentially virus-free seedlings. Therefore, this technique has been widely used in the cultivation of virus-free flower plants. 2. Requirements for laboratory and equipment for flower tissue culture Flower tissue culture is the cultivation of flowers under artificial control. It is a new production technology for
