Problems solved by technology

At present, with the development of economy and Emei tourism, scientific research and collection of orchid lovers, while the ecological environment of this plant has been destroyed, it has also suffered from excessive excavation, which has caused a great threat to wild populations
[0004] In my country, there is a lack of research on the plants of G. emei. We only know the rough information about the narrow distribution area, the approximate distribution location, and the extremely rare number of g. emei. The research on the reproduction of g. Scientists failed to reproduce Emei grove tongue plant

Embodiment 1

[0025] a. Acquisition of capsules: After near-field protection and years of growth adaptability research, select plants with strong adaptability and vigorous growth. During the flowering period, select plants from different populations for artificial pollination. The seed setting rate is 100%. Obtained For healthy capsules, mark the hybrid combination and pollination time when pollinating, and the capsules are picked when they are not cracked 385 days after pollination;

[0026] b. Treatment of capsules: pick the uncracked capsules of Emei groves, rinse with tap water for 8 minutes, put them on the ultra-clean workbench for standby, and treat them with alcohol with a mass concentration of 75% for 35 seconds and a mass concentration of 0.1% under sterile conditions. Sterilize with mercuric chloride solution for 18 minutes, rinse with sterile water for 6 times, and then use sterile filter paper to absorb the water on the surface of the capsule; In a Petri dish, mix the seeds eve...

Embodiment 2

[0032] a. Acquisition of capsules: After near-field protection and years of growth adaptability research, select plants with strong adaptability and vigorous growth. During the flowering period, select plants from different populations for artificial pollination. The seed setting rate is 100%. Obtained Healthy capsules; mark the hybrid combination and pollination time when pollinating, and the capsules are picked when they are not cracked 520 days after pollination.

[0033] b. Treatment of capsules: pick the uncracked capsules of Glossia emeiensis, wash them with tap water for 8 minutes, and put them on the ultra-clean workbench for later use. Under aseptic conditions, they were treated with 75% alcohol for 35 seconds, sterilized with 0.1% mercuric chloride solution for 18 minutes, rinsed with sterile water for 6 times, and then blotted dry the water on the surface of the capsule with sterile filter paper. Cut open the sterile capsule with a sterilized knife;

[0039] a. Acquisition of capsules: After near-field protection and years of growth adaptability research, select plants with strong adaptability and vigorous growth. During the flowering period, select plants from different populations for artificial pollination. The seed setting rate is 100%. Obtained For healthy capsules, mark the hybrid combination and pollination time when pollinating, and the capsules are picked when they are not cracked 500 days after pollination;

[0040] b. Treatment of capsules: pick the uncracked capsules of Eucalyptus emei, rinse them with tap water for 5 minutes, put them on the ultra-clean workbench for later use, and treat them with alcohol with a mass concentration of 75% for 30 seconds and a mass concentration of 0.1% under sterile conditions. Sterilize with mercuric chloride solution for 15 minutes, and rinse with sterile water for 4 times respectively, and then use sterile filter paper to blot the water on the surface of the capsule; In a Pet...

Abstract

The invention discloses a method for obtaining capsules of Emei grouse and using its seeds to propagate and obtain seedlings, belonging to the technical field of plant propagation. The capsules are obtained by artificial pollination between plants with a certain genetic distance, and the seed setting rate is 100% %; Established a rapid propagation system for Emei gros. , providing resource base and technical support for its sustainable utilization, and actively promoting the industrialization of this plant resource, which has extremely important practical significance and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for obtaining capsules of Eurythia emei and a rapid seed propagation method thereof. Background technique [0002] Emei trough tongue ( Holcoglossum omeiense ) is a low-mountain plant type in the genus Gossamia. It is an endemic species in the Emeishan area of ​​my country and is only distributed in the middle and low mountain areas of this area. Due to its extremely narrow distribution area and extremely small population and individual numbers, the Emei grovegloss is a rare and endangered species, and has been included in the "Very Small Population (Narrow Distribution) Protected Species", "China Biodiversity Red List (Higher Plant Volume) )", "China Species Red List (Plant Parts)" and "China Rare and Endangered Plants Illustrated Handbook". At present, because of the extremely small population of wild plants in the country, the Emei Trough tongu...
