Abstract

The invention discloses a tissue culture and rapid propagation method for Acer rubrum 'Brandywine'. The Acer rubrum 'Brandywine' is an Aceraceae Acer tall deciduous tree, has the characteristics of high adaptability, drought resistance, temperature resistance, growth fastness and the like and is a fine tree species for landscaping. At present, the Acer rubrum 'Brandywine' mainly propagates seedlings with a seed sowing propagation method, but the seed fruiting rate is lower, so that supply of a large number of seedlings of the Acer rubrum 'Brandywine' is limited. According to the method, stems with buds are used as explants, tissue-cultured regenerated plants of the Acer rubrum 'Brandywine' are successfully obtained through steps of induction, multiplication, rooting, acclimatization, transplantation and the like, a systematic tissue-cultured plant regeneration system for the Acer rubrum 'Brandywine' is established, and a reference is provided for mass factory culture of the seedlings of the Acer rubrum 'Brandywine'.

Description

A kind of American red-maple tissue culture and rapid propagation method
Technical field
The present invention relates to the method for Plant Tissue Breeding in agricultural biotechnologies, specifically, relate to a kind of American red-maple tissue culture and rapid propagation method.
Background technology
American red-maple (Acer rubrum ' brandywine'), have another name called red maple, the red maple in North America, Canada Red maple, northern red maple, scarlet maple, scarlet maple, marsh maple etc., be the tall and big deciduous tree of Aceraceae Acer L, having the features such as strong adaptability, drought-enduring, heatproof, growing way are swift and violent, is the fine tree species of afforestation.Spring, young leaves was general red, mutually shone with the red flower of bunchiness; Summer, branches and leaves were lined: autumn, leaf was that azarin turns over yellow, to finally presenting cerise, heard long when continuing.Tree-like upright and on, tree crown is circular, grey bark.Annual various colors, spring blooms, monoecism, premium look, and fruit has wing, red.The transplanting survival rate of American red-maple is very high, and growth potential is strong, and have resistance, can adapt to the particular surroundings in street, cultivation management workload is little, and American red-maple damage by disease and insect is little, and after finding, process can not impact trees in time.American red-maple has many advantages of plane tree, very popular, and American red-maple gardening kind has become the outstanding Afforestation Landscape seeds of alternative fragrant camphor tree and Chinese parasol tree, is " king of street tree " of new generation.
Current American red-maple mainly carries out seedling breeding with planting seed modes of reproduction, but because of seed-setting rate lower, because which limit the supply of a large amount of seedling of American red-maple.Plant Tissue Breeding has that breeding is fast, cost less, growth coefficient high; the present invention take stem with bud as explant; through inducing, breed, to take root and the step such as acclimatization and transplants successfully obtains American red-maple Regenerated Plantlets; establishing the red mangrove tissue culture plants regenerating system of system, providing reference for realizing the nursery of American red-maple seedling scale factory.
