Embodiment 1

[0036] The method for efficient breeding of a kind of Danish hibiscus excellent strain of the present embodiment comprises the following steps:

[0037] (1) Take materials

[0038] The leaves with petioles of the potted Danish hibiscus introduced from Denmark with excellent agronomic traits (one or more traits in high yield, large flowers, long flowering period, and good stress resistance) were selected as explants; wherein, The leaf with petiole is obtained as follows: the leaf with petiole is broken off from the joint between the Danish hibiscus stem and the petiole;

[0039] (2) Pretreatment of explants

[0040] The Danish hibiscus leaf with petiole in the step (1) is placed under running water and rinsed for 10 minutes, and then the surface is disinfected for 5 minutes by a potassium permanganate disinfection solution with a concentration of 0.5‰, and then dried in the shade after being pulled out, and set aside;

[0041] (3) Induction treatment of explant adventitious r...

Embodiment 2

[0048] The method for efficient breeding of a kind of Danish hibiscus excellent strain of the present embodiment comprises the following steps:

[0049] (1) Take materials

[0050]Select the stem section with leaves of the potted Danish hibiscus introduced from Denmark in the greenhouse with excellent agronomic traits (one or more of high yield, large flowers, long flowering period, and good stress resistance) as explants; , the stem section with leaves is drawn as follows: cut the stem section with scissors into micro-stem sections with 1 axillary bud and 1 leaf with a length of 1.0-3.0 cm;

[0051] (2) Pretreatment of explants

[0052] The stem section of Danish hibiscus leaves in step (1) is placed under running water and rinsed for 15 minutes, then the surface is disinfected for 10 minutes by a potassium permanganate disinfection solution with a concentration of 0.75 ‰, and then dried in the shade after being pulled out for subsequent use;

[0053] (3) Induction treatmen...

Embodiment 3

[0060] The method for efficient breeding of a kind of Danish hibiscus excellent strain of the present embodiment comprises the following steps:

[0061] (1) Take materials

[0062] Select the leaves with petioles and the stems with leaves of the potted Danish hibiscus introduced from Denmark in the greenhouse with excellent agronomic traits (one or more of high yield, large flowers, long flowering period, and good stress resistance) As an explant; Wherein, the method for drawing the leaves with petioles is: breaking off the leaves with petioles at the junction of the Danish hibiscus stem and the petiole; 1.0-3.0 cm long microstem segment with 1 axillary bud and 1 leaf;

[0063] (2) Pretreatment of explants

[0064] Put the leaves with petioles and the stems with leaves of the Danish hibiscus in step (1) under running water for rinsing for 20 minutes, then disinfect the surface with a potassium permanganate disinfection solution with a concentration of 1.0‰ for 15 minutes, ta...

Abstract

The invention discloses an efficient cultivation method for excellent strains of Danish hibiscus. The method comprises the following steps of material collecting, explant pretreatment, explant adventitious root induction treatment, explant field planting and explant seedling establishment management. The method has the advantages that material collecting is convenient, the materials are rich, and regeneration plants can keep the original excellent character of a maternal plant; operation is easy, the reproduction speed is high, and meanwhile the type and concentration of a rooting promotion solution are strictly optimized and controlled; type and concentration selection of disinfectant, nutritious fluid, nutritious substrates and the like is strictly matched with essential elements needed in the Danish hibiscus plant growing process, and introduction of harmful elements is avoided; explants are placed in a mixed nutritious substrate to directly root in a greenhouse, seedling establishment is achieved through one step, and influences and limits of natural factors such as seasons and territories are avoided; the cost is low, operation is easy, mastering is easy, reproduction expanding can be achieved, and the method is suitable for factory cultivation of the Danish hibiscus.

Description

technical field [0001] The invention relates to the field of hibiscus breeding, in particular to a method for efficient breeding of fine Danish hibiscus strains. Background technique [0002] Hibiscus is a perennial plant of the Malvaceae Hibiscus genus. Because of its long flowering period, various flower colors, strong adaptability, and easy cultivation and management, it is cultivated in all parts of my country's north and south. [0003] As a new improved variety of hibiscus, Danish hibiscus not only has dark green leaves, but also has rich flower colors, such as red, orange, yellow, pink, and white; it also has a long flowering period and many flower buds. Each pot can reach more than 30 flower buds. The longest period is about 3-5 days. After flowering, as long as sufficient vegetative growth is ensured, it can bloom year-round. In addition, Danish hibiscus has strong disease resistance and can be cultivated indoors and outdoors, with high ornamental value. [0004] I...
