Abstract

The invention provides a method for enabling a woody plant material to form an adventitious root and grow into an own-rooted seedling. The method includes selecting a full annual lignified branch or a cryptophytic perennial branch of the woody plant, maintaining the humidity needed for the survival of the branch, keeping germinal shoots etiolation and delaying lignification through controlling light, and inducing lateral twigs to root. The method is convenient to operate, low-carbon, environment-friendly, low in cost, and capable of enabling tree species difficult to obtain own-rooted seedlings through existing methods to obtain own-rooted seedlings easily and increasing the material selecting range of own-rooted seedling of tree species easy to cut.

Description

technical field

[0001] The invention relates to a method for promoting woody plant materials to form adventitious roots and cultivate them into self-rooted seedlings, in particular to a method for promoting hard-to-root woody plant materials to form adventitious roots and cultivate them into self-rooted seedlings, belonging to the technical field of woody plant propagation. Background technique

[0002] Self-rooted seedlings have the irreplaceable advantages of grafted seedlings and seedlings in production and scientific research. They not only have the advantage of maintaining the excellent genetic traits of the female parent, but also have good consistency.

[0003] At present, the methods for producing self-rooted seedlings of woody plants mainly include cutting, layering, branching and tissue culture. The first three are widely circulated and ancient traditional methods, which have been used until now, while the latter is a new one that only appeared in the 20th century. ...
