Problems solved by technology

[0003] However, the degeneration of Lilium longya species is very serious in production, and the diseases that endanger the rhizomes are increasing year by year, such as lily asymptomatic virus (LSV) and lily mottled virus (LMoV), which affect the output of lily longya and greatly restrict the lily longya industry. development of
In the prior art, the detoxification method of cultivars is mainly used to solve the degradation problem of Lilium argentina, but the detoxification effect of the stem apex is limited, so it is urgent to solve the problem of the degeneration of Lily aralia species

Embodiment 1

[0034] The present embodiment provides a kind of method that prevents lily of dragon tooth from degenerating, specifically comprises the following steps:

[0035] S1. Seed selection: look for the native species of Lilium longya in the wild, take its fruit as an explant, and carry out sterilization treatment: rinse the fruit with tap water, dry it, then soak it with 75% alcohol for 30 seconds, and then put it in dry on an alcohol lamp;

[0036] S2. Cultivation: Cut the treated fruit in step S1, peel off the embryo and inoculate it on the medium for primary culture, subculture and rooting culture, wherein the medium formula for the primary culture is MS+0.3mg / L6 -BA+sucrose 3%, the medium formula of the 2nd to 5th generations is MS+0.2mg / L 6-BA+3% sucrose, the medium formula of the 5th to 10th generations is MS+0.02mg / L 6-BA+3% sucrose;

[0037] S3. Seedling hardening and transplanting: the hardening process is carried out in a greenhouse at an altitude of 1000m. The hardening ...

Abstract

The invention discloses a method for preventing degeneration of longya lilium. The method comprises the steps of seed selection, embryo stripping culture, acclimatization and transplantation and scalecutting. Fruits of native species of wild longya lilium are used as explants, excellent sexual progenies are selected by a sexual recovery method, and excellent bulbs are bred in combination with a scale cutting method, so that the problem of degeneration of longya lilium varieties is effectively solved.

Description

technical field [0001] The invention relates to the technical field of lily breeding, and more particularly, relates to a method for preventing lily from degeneration. Background technique [0002] Longya lily is cultivated in South China, East China, and Central China, and is distributed in Hunan, Hubei, Zhejiang, Henan, Hebei, Shaanxi and other provinces at an altitude of 300-900 meters. It is mainly produced in Shaoyang, Longhui, Shaodong, Jiangxi Wanzai and other places in Hunan Province. It has the medicinal effects of nourishing the lungs and nourishing yin, clearing the heart and calming the nerves. Generally, the yield of fresh lilies per mu can reach 1000-2000kg, which has high economic benefits. [0003] However, the degeneration of Lilium longya species is very serious in production, and the diseases that endanger the rhizomes are increasing year by year, such as lily asymptomatic virus (LSV) and lily mottled virus (LMoV), which affect the output of lily longya an...
