Problems solved by technology

Sterile conditions are the main reason for the tedious and expensive tissue culture propagation
[0005] So far, there has not been a report on an inexpensive method that can take advantage of the characteristics of low lignification branches and easy rooting, and does not require high environmental conditions and is easy to operate.

Embodiment 1

[0031] On January 25, 2011, the dormant branches of Caryaillinoensis, a cultivated plant of the Juglandaceae family, were selected and cut into 20 stems with a length of 20 cm and a diameter of 10 to 15 mm. They were used as cuttings and placed in a plastic vest bag. Moss keeps moisture, and keep 2 / 3 of the space in the bag as air, and keep it away from light. Lateral buds began to germinate one after another in late March. At the beginning of April, the length of the young shoots reaches 3-5cm, and weak scattered light begins to penetrate at this time; remove too many new shoots, and only keep 2 new shoots on each cutting. On April 26, high-voltage electrostatic field (HVEF) treatment: the intensity was 45KV / cm, and the time was 2 hours; rooting powder was soaked, and the rooting powder was: 2 parts of α-naphthaleneacetic acid, 1 part of indole butyric acid, ABT7 rooting powder 0.5 parts of powder, 5 parts of potassium tetraborate, 3 parts of potassium dihydrogen phosphate, ...

Embodiment 2

[0034] On February 7th, 2012, the wild plants of the Rosaceae Rubuscoreanus stolons were selected, cut into 50 stems with a length of 15 cm, and placed in a plastic waistcoat bag as cuttings. Keep 2 / 3 of the space in the bag as air, and keep it away from light. Open the plastic vest bag once a week to check and ventilate once a week, spray moisture, and the lateral buds will start to germinate in late March. When the length of the young shoots reaches 3 cm, weak scattered light begins to penetrate; remove too many new shoots, and only keep 2 new shoots on each cutting. On April 3, the high-voltage electrostatic field (HVEF) treatment: the intensity was 45KV / cm, and the time was 2 hours; the rooting powder was soaked, and the rooting powder was: 2 parts of α-naphthaleneacetic acid, 1 part of indole butyric acid, ABT7 rooting powder 0.5 parts, 5 parts of potassium tetraborate, 3 parts of potassium dihydrogen phosphate, and 10.5 parts of vitamin B. Soak the lower part of the cut...

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. ...
