Problems solved by technology

[0005] In order to solve the problem of narrow adaptability of existing tree rose cultivation, the judgment of affinity between rootstock and scion is based on experience, weak operability, low grafting survival rate, and long ornamental lifespan. The short technical problem is that the present invention provides a widely adaptable method for cultivating tree-like roses by using seed stock, which has the characteristics of strong operability, high survival rate, and long viewing life.

Embodiment 1

[0061] Embodiment 1 utilizes Sichuan-Yunnan rose to cultivate the tree-like rose of large flower type, medium flower type and small flower type

[0062] (1) Breeding of the rootstock of the rose genus: select the seeds of the Sichuan-Yunnan rose self-crossing in that year, and carry out the following operations to it:

[0063] 1) The seeds were refrigerated: on December 11, 2008, under the conditions of a constant temperature of 4°C and a humidity of 80%, the seeds were refrigerated in dark light for 60 days.

[0064] 2) Sterilize the seeds: On February 9 of the following year, soak them in a potassium permanganate solution with a concentration of 4‰w / w (mass percentage) for 20 minutes, and then rinse them with sterile water 3 times.

[0065] 3) Water absorption treatment for seeds: soak the sterilized seeds with sterile water at a high temperature of 97°C for 5 minutes, put the seeds into sterile water at room temperature, change the water every night, and soak for 5 days.

Abstract

The invention discloses a method for cultivating tree-shaped Chinese roses by using seedling stocks. The method comprises the following steps: selecting five pairs of SSR primers, accurately determining the affinity of scions and rootstocks by adopting an SSR molecular marker technology, and then selecting the scions with strong affinity to complete the cultivation of the tree-shaped Chinese rose. According to the method, domestic native rosa multiflora seedlings are used as rootstocks, so that damage behaviors to wild rosa multiflora can be effectively reduced, the grafting survival rate of the rootstocks and scions can be greatly increased, and meanwhile, the ornamental life of the tree-shaped Chinese roses can be scientifically prolonged.

Description

technical field [0001] The invention belongs to the technical field of landscaping application of woody flowers, and specifically relates to the breeding of seedlings, the determination of grafting affinity, and the methods of grafting and shaping. Background technique [0002] Rose (Rosa hybrida) is a plant of the genus Rosa in the family Rosaceae. Tree rose, also known as rose tree, rose tree, tree rose, lollipop rose, etc., is a rose rootstock with an upright main branch through horticultural means (cutting or sowing, root raising, stem growth, grafting, pruning, etc.) , shaping and other measures) to cultivate a new type of rose. The corolla of tree-like roses is higher off the ground than ordinary flowers, has better ventilation, and is less susceptible to pests and diseases. Its appearance is unique in shape, noble and elegant, with distinct layers, which is refreshing in visual effect. At present, with the continuous upgrading of consumers' aesthetic needs, tree ro...
