Rose seedling raising method

Abstract

The invention provides a rose seedling raising method. The method is characterized by comprising steps as follows: selection of an explant material, soaking treatment, disinfection treatment, cutting culture, expanding propagation, rooting culture and transplanting to anutrition cup. According to the rose seedling raising method, the survival rate reaches 99.4% or higher, survival rate of transplanting after outplanting reaches 99.0% or higher, uniformity of the cultured rose seedlings is high, height difference of the seedlings is within 1.2 cm, the root-growing rate reaches 99.5% or higher, and during transplanting, the number of rooting of each rose seedling is 12-13, and the root length is 3.6-4 cm;by means of in-vitro self-breeding, the problem about the cutting branch source is solved, consumption of a large quantity of rose branches is not required, propagation efficiency and propagation coefficient are increased, and each rose plant is proliferated 9-12 times each time in terms of cutting of 3-4 young and tender stem segments; the utilization rate of maternal plantbreeding sections reaches 96% or higher.

Description

technical field [0001] The invention relates to a rose seedling raising method, which belongs to the technical field of seedling raising. Background technique [0002] The existing rose seedling raising method mainly adopts the cutting method, and the length of the cuttings is generally selected to be greater than 10cm. If the length of the cuttings is less than 10cm, the nutrients stored in the cuttings are less, and the cuttings die due to insufficient nutrient supply during the cutting process, resulting in The survival rate is low. [0003] CN102612971A discloses a rose cutting propagation method, in which the cutting paper strips collected are robust annual paper strips with a transverse diameter of not less than 1 cm and a length of 50-70 cm; [0004] CN103918535A discloses a method for raising seedlings of Rose Damascena, in which the length of cuttings collected is 10-15 cm. [0005] But the length selection of cuttings is too long, then need a certain amount of ...

AI Technical Summary

Problems solved by technology

[0005] However, if the length of the cuttings is selected too long, a certain amount of female plants are needed as the source of the scion, resulting in low reproduction coefficient, low utilization rate of the seed nodes of the female plants, and a small number of overall multiplication.

[0006] The conventional tissue culture rapid propagation technology has the advantages of high reproduction coefficient and high reproduction rate, but the disadvantages are: high technical content and the need for a variety of hormones to be used in conjunction. Generally, the callus is induced first, and then the bud differentiation is induced. There are many steps , The cultivation cycle is long, and when the cultured tissue culture seedlings are transplanted into cup seedlings, it takes a long time to harden the seedlings, and the survival rate is affected during the hardening process
