Abstract

The invention discloses a salix saposhnikovii tissue culture method. The salix saposhnikovii tissue culture method comprises the following steps of: (1) material selection and disinfection treatment; (2) cultivation of tube seedlings; (3) proliferation and rooting cultivation; and (4) acclimatization of seedlings and transplanting. The salix saposhnikovii tissue culture method provided by the invention is high in propagation efficiency and small in occupied space without being limited by seasons or outside environments, needs few parent materials, and can provide a large number of high-quality nursery stocks in a short term. In addition, the successful establishment of an efficient salix saposhnikovii tissue regeneration system has great significance for the development of work such as biological research, genetic improvement and multi-target molecular breeding of salix saposhnikovii.

Description

Technical field [0001] The invention relates to a method for breeding willows, in particular to a method for tissue culture of shrub willows. Background technique [0002] Willow is a generic term for Salix plants in the Salicaceae family. There are 526 species in the world, mainly distributed in the temperate regions of the northern hemisphere. There are 257 species, 120 varieties and 33 varieties in China, most of which are shrub willow. Shrub willow has a wide distribution, fast growth, high yield, high calorific value, strong stress resistance, easy renewal, and a wide range of wood uses. It is an important tree species for protection forests, water and soil conservation forests, landscape forests and timber forests, and is also an energy tree species that has attracted much attention . In particular, there are very rich genetic variation among shrub willow species and their hybrid families and clones. Therefore, the selection of fast-growing, high-biomass, salt-tolerant, a...
